# @ar.io/sdk
[](https://codecov.io/gh/ar-io/ar-io-sdk)
The Solana-native SDK for the AR.IO network. Provides typed
client classes (`ARIO`, `ANT`, `ANTRegistry`), PDA helpers,
deserializers, and escrow primitives for the AR.IO protocol on Solana.
Codama-generated instruction builders and account decoders are
supplied by [`@ar.io/solana-contracts`](https://www.npmjs.com/package/@ar.io/solana-contracts).

## Installation
Requires `node>=v18.0.0`.
```shell
npm install @ar.io/sdk
```
or
```shell
yarn add @ar.io/sdk
```
## Quick Start
```typescript
import { ARIO } from '@ar.io/sdk';
import { createSolanaRpc } from '@solana/kit';
const rpc = createSolanaRpc('https://api.mainnet-beta.solana.com');
const ario = ARIO.init({ rpc });
const gateways = await ario.getGateways();
```
Write operations need a `@solana/kit` signer plus an `rpcSubscriptions`
client (used by kit's `sendAndConfirmTransaction`):
```typescript
import { ARIO } from '@ar.io/sdk';
import {
createSolanaRpc,
createSolanaRpcSubscriptions,
createKeyPairSignerFromBytes,
} from '@solana/kit';
import { readFileSync } from 'node:fs';
const rpc = createSolanaRpc('https://api.mainnet-beta.solana.com');
const rpcSubscriptions = createSolanaRpcSubscriptions(
'wss://api.mainnet-beta.solana.com',
);
const signer = await createKeyPairSignerFromBytes(
new Uint8Array(JSON.parse(readFileSync('keypair.json', 'utf8'))),
);
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
await ario.buyRecord({
name: 'foo',
type: 'lease',
years: 1,
processId: '',
});
```

## Usage
The SDK is published as an ES module (`"type": "module"`) and is
compatible with modern bundlers such as Webpack, Rollup, ESbuild, and
Vite. CommonJS consumers should migrate to ESM (Node 18+ supports ESM
natively). Refer to the [examples] directory to see how to use the SDK
in various environments.
### Subpath exports
- `@ar.io/sdk` — main entry. `ARIO`, `ANT`, `ANTRegistry`, Solana
client classes, PDA helpers, deserializers, escrow primitives.
- `@ar.io/sdk/solana` — alias of the main entry (kept for one release
while consumers migrate from the previous subpath layout).
### Web
> [!WARNING]
> Polyfills are not provided by default for bundled web projects (Vite,
> ESBuild, Webpack, Rollup, etc.). Depending on your bundler config, you
> will need polyfills for `crypto`, `process` and `buffer`. Refer to
> [examples/webpack] and [examples/vite] for examples.
```javascript
import { ARIO } from '@ar.io/sdk';
import { createSolanaRpc } from '@solana/kit';
const ario = ARIO.init({
rpc: createSolanaRpc('https://api.mainnet-beta.solana.com'),
});
const gateways = await ario.getGateways();
```
### Browser bundle
```html
// replace <version> with a release version
import { ARIO } from 'https://github.com/ar-io/ar-io-sdk/releases/download/v<version>/web.bundle.min.js';
import { createSolanaRpc } from 'https://esm.sh/@solana/kit@6';
const ario = ARIO.init({
rpc: createSolanaRpc('https://api.mainnet-beta.solana.com'),
});
const gateways = await ario.getGateways();
```
### TypeScript
The SDK ships TypeScript types alongside the JS output. Types are
exported from `./lib/types/solana/index.d.ts` and resolve automatically
for ESM consumers.
> [!NOTE]
> TypeScript 5.3+ is recommended (the SDK uses `nodenext` module
> resolution with `.js` extensions in relative imports).
## ARIO Contract
### General
#### `init({ rpc, rpcSubscriptions?, signer? })`
Factory function that creates a read-only or writeable ARIO client.
Providing `signer` plus `rpcSubscriptions` enables write methods
(`joinNetwork`, `delegateStake`, `buyRecord`, etc.). Without a signer,
the client is read-only.
```typescript
import { ARIO } from '@ar.io/sdk';
import {
createSolanaRpc,
createSolanaRpcSubscriptions,
createKeyPairSignerFromBytes,
} from '@solana/kit';
const rpc = createSolanaRpc('https://api.mainnet-beta.solana.com');
// read-only client
const ario = ARIO.init({ rpc });
// read-write client (needs rpcSubscriptions for sendAndConfirm)
const rpcSubscriptions = createSolanaRpcSubscriptions(
'wss://api.mainnet-beta.solana.com',
);
const signer = await createKeyPairSignerFromBytes(/* 64-byte secret key */);
const arioWrite = ARIO.init({ rpc, rpcSubscriptions, signer });
```
#### `getInfo()`
Retrieves the information of the ARIO process.
```typescript
const ario = ARIO.init({ rpc });
const info = await ario.getInfo();
```
Output
```json
{
"Name": "AR.IO",
"Ticker": "ARIO",
"Logo": "",
"Denomination": 6,
"Handlers": [],
"LastCreatedEpochIndex": 0,
"LastDistributedEpochIndex": 0,
"totalSupply": 1000000000000000,
"protocolBalance": 0,
"epochSettings": {
"durationMs": 86400000,
"prescribedNameCount": 25,
"maxObservers": 50
}
}
```
> **Note**: `Handlers`, `LastCreatedEpochIndex`, and `LastDistributedEpochIndex`
> are placeholders on Solana (returned for backwards-compatible field shape
> with consumer code). `totalSupply` / `protocolBalance` are live reads from
> the `ArioConfig` PDA; `epochSettings` is live from the `EpochSettings`
> PDA. See `src/solana/io-readable.ts` for the exact projection.
#### `getTokenSupply()`
Retrieves the total supply of tokens, returned in mARIO. The total supply includes the following:
- `total` - the total supply of all tokens
- `circulating` - the total supply minus locked, withdrawn, delegated, and staked
- `locked` - tokens that are locked in the protocol (a.k.a. vaulted)
- `withdrawn` - tokens that have been withdrawn from the protocol by operators and delegators
- `delegated` - tokens that have been delegated to gateways
- `staked` - tokens that are staked in the protocol by gateway operators
- `protocolBalance` - tokens that are held in the protocol's treasury. This is included in the circulating supply.
```typescript
const ario = ARIO.init({ rpc });
const supply = await ario.getTokenSupply();
```
Output
```json
{
"total": 1000000000000000000,
"circulating": 998094653842520,
"locked": 0,
"withdrawn": 560563387278,
"delegated": 1750000000,
"staked": 1343032770199,
"protocolBalance": 46317263683761
}
```
#### `getBalance({ address })`
Retrieves the balance of the specified wallet address.
```typescript
const ario = ARIO.init({ rpc });
// the balance will be returned in mARIO as a value
const balance = await ario
.getBalance({
address: "QGWqtJdLLgm2ehFWiiPzMaoFLD50CnGuzZIPEdoDRGQ",
})
.then((balance: number) => new mARIOToken(balance).toARIO()); // convert it to ARIO for readability
```
Output
```json
100000
```
#### `getBalances({ cursor, limit, sortBy, sortOrder })`
Retrieves the balances of the ARIO process in `mARIO`, paginated and sorted by the specified criteria. The `cursor` used for pagination is the last wallet address from the previous request.
```typescript
const ario = ARIO.init({ rpc });
const balances = await ario.getBalances({
cursor: "-4xgjroXENKYhTWqrBo57HQwvDL51mMdfsdsxJy6Y2Z_sA",
limit: 100,
sortBy: "balance",
sortOrder: "desc",
});
```
Output
```json
{
"items": [
{
"address": "-4xgjroXENKYhTWqrBo57HQwvDL51mMvSxJy6Y2Z_sA",
"balance": 1000000
},
{
"address": "-7vXsQZQDk8TMDlpiSLy3CnLi5PDPlAaN2DaynORpck",
"balance": 1000000
}
// ...98 other balances
],
"hasMore": true,
"nextCursor": "-7vXsQZQDk8TMDlpiSLy3CnLi5PDPlAaN2DaynORpck",
"totalItems": 1789,
"sortBy": "balance",
"sortOrder": "desc"
}
```
#### `transfer({ target, qty })`
Transfers `mARIO` to the designated `target` recipient address. Requires `signer` to be provided on `ARIO.init` to sign the transaction.
_Note: Requires `signer` to be provided on `ARIO.init` to sign the transaction._
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.transfer({
target: 'RecipientSolanaPubkeyBase58',
qty: new ARIOToken(1000).toMARIO(),
});
```
### Networks
The SDK talks to whatever cluster your `@solana/kit` RPC client points
at — mainnet-beta by default. For devnet or a local validator, override
the RPC URL and (on any non-mainnet cluster) the per-program addresses:
```typescript
import { ARIO } from '@ar.io/sdk';
import { createSolanaRpc, address } from '@solana/kit';
const ario = ARIO.init({
rpc: createSolanaRpc('https://api.devnet.solana.com'),
coreProgramId: address(''),
garProgramId: address(''),
arnsProgramId: address(''),
antProgramId: address(''),
});
```
On localnet (Surfpool) source program IDs from
`migration/localnet/out/localnet.env` in the `solana-ar-io` monorepo.
### Vaults
#### `getVault({ address, vaultId })`
Retrieves the locked-balance user vault of the ARIO process by the specified wallet address and vault ID.
```typescript
const ario = ARIO.init({ rpc });
const vault = await ario.getVault({
address: "QGWqtJdLLgm2ehFWiiPzMaoFLD50CnGuzZIPEdoDRGQ",
vaultId: "vaultIdOne",
});
```
Output
```json
{
"balance": 1000000,
"startTimestamp": 123,
"endTimestamp": 4567
}
```
#### `getVaults({ cursor, limit, sortBy, sortOrder })`
Retrieves all locked-balance user vaults of the ARIO process, paginated and sorted by the specified criteria. The `cursor` used for pagination is the last wallet address from the previous request.
```typescript
const ario = ARIO.init({ rpc });
const vaults = await ario.getVaults({
cursor: "0",
limit: 100,
sortBy: "balance",
sortOrder: "desc",
});
```
Output
```json
{
"items": [
{
"address": "QGWqtJdLLgm2ehFWiiPzMaoFLD50CnGuzZIPEdoDRGQ",
"vaultId": "vaultIdOne",
"balance": 1000000,
"startTimestamp": 123,
"endTimestamp": 4567
},
{
"address": "QGWqtJdLLgm2ehFWiiPzMaoFLD50CnGuzZIPEdoDRGQ",
"vaultId": "vaultIdTwo",
"balance": 1000000,
"startTimestamp": 123,
"endTimestamp": 4567
}
// ...98 other addresses with vaults
],
"hasMore": true,
"nextCursor": "QGWqtJdLLgm2ehFWiiPzMaoFLD50CnGuzZIPEdoDRGQ",
"totalItems": 1789,
"sortBy": "balance",
"sortOrder": "desc"
}
```
#### `vaultedTransfer({ recipient, quantity, lockLengthMs, revokable })`
Transfers `mARIO` to the designated `recipient` address and locks the balance for the specified `lockLengthMs` milliseconds. The `revokable` flag determines if the vaulted transfer can be revoked by the sender.
_Note: Requires `signer` to be provided on `ARIO.init` to sign the transaction._
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.vaultedTransfer(
{
recipient: "-5dV7nk7waR8v4STuwPnTck1zFVkQqJh5K9q9Zik4Y5",
quantity: new ARIOToken(1000).toMARIO(),
lockLengthMs: 1000 * 60 * 60 * 24 * 365, // 1 year
revokable: true,
},
// optional additional tags
{ tags: [{ name: "App-Name", value: "My-Awesome-App" }] },
);
```
#### `revokeVault({ recipient, vaultId })`
Revokes a vaulted transfer by the recipient address and vault ID. Only the sender of the vaulted transfer can revoke it.
_Note: Requires `signer` to be provided on `ARIO.init` to sign the transaction._
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.revokeVault({
recipient: "-5dV7nk7waR8v4STuwPnTck1zFVkQqJh5K9q9Zik4Y5",
vaultId: "IPdwa3Mb_9pDD8c2IaJx6aad51Ss-_TfStVwBuhtXMs",
});
```
#### `createVault({ lockLengthMs, quantity })`
Creates a vault for the specified `quantity` of mARIO from the signer's balance and locks it for the specified `lockLengthMs` milliseconds.
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.createVault({
lockLengthMs: 1000 * 60 * 60 * 24 * 365, // 1 year
quantity: new ARIOToken(1000).toMARIO(),
});
```
#### `extendVault({ vaultId, extendLengthMs })`
Extends the lock length of a signer's vault by the specified `extendLengthMs` milliseconds.
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.extendVault({
vaultId: "vaultIdOne",
extendLengthMs: 1000 * 60 * 60 * 24 * 365, // 1 year
});
```
#### `increaseVault({ vaultId, quantity })`
Increases the balance of a signer's vault by the specified `quantity` of mARIO.
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.increaseVault({
vaultId: "vaultIdOne",
quantity: new ARIOToken(1000).toMARIO(),
});
```
### Gateways
#### `getGateway({ address })`
Retrieves a gateway's info by its staking wallet address.
```typescript
const ario = ARIO.init({ rpc });
const gateway = await ario.getGateway({
address: "-7vXsQZQDk8TMDlpiSLy3CnLi5PDPlAaN2DaynORpck",
});
```
Output

```
#### `getGateways({ cursor, limit, sortBy, sortOrder })`
Retrieves registered gateways of the ARIO process, using pagination and sorting by the specified criteria. The `cursor` used for pagination is the last gateway address from the previous request.
```typescript
const ario = ARIO.init({ rpc });
const gateways = await ario.getGateways({
limit: 100,
sortOrder: "desc",
sortBy: "operatorStake",
});
```
Available `sortBy` options are any of the keys on the gateway object, e.g. `operatorStake`, `start`, `status`, `settings.fqdn`, `settings.label`, `settings.note`, `settings.port`, `settings.protocol`, `stats.failedConsecutiveEpochs`, `stats.passedConsecutiveEpochs`, etc.

```
#### `joinNetwork(params)`
Joins a gateway to the ar.io network via its associated wallet.
_Note: Requires `signer` to be provided on `ARIO.init` to sign the transaction._
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.joinNetwork(
{
qty: new ARIOToken(10_000).toMARIO(), // minimum operator stake allowed
autoStake: true, // auto-stake operator rewards to the gateway
allowDelegatedStaking: true, // allows delegated staking
minDelegatedStake: new ARIOToken(100).toMARIO(), // minimum delegated stake allowed
delegateRewardShareRatio: 10, // percentage of rewards to share with delegates (e.g. 10%)
label: "john smith", // min 1, max 64 characters
note: "The example gateway", // max 256 characters
properties: "FH1aVetOoulPGqgYukj0VE0wIhDy90WiQoV3U2PeY44", // Arweave transaction ID containing additional properties of the Gateway
observerWallet: "0VE0wIhDy90WiQoV3U2PeY44FH1aVetOoulPGqgYukj", // wallet address of the observer, must match OBSERVER_WALLET on the observer
fqdn: "example.com", // fully qualified domain name - note: you must own the domain and set the OBSERVER_WALLET on your gateway to match `observerWallet`
port: 443, // port number
protocol: "https", // only 'https' is supported
},
// optional additional tags
{ tags: [{ name: "App-Name", value: "My-Awesome-App" }] },
);
```
#### `leaveNetwork()`
Sets the gateway as `leaving` on the ar.io network. Requires `signer` to be provided on `ARIO.init` to sign the transaction. The gateways operator and delegate stakes are vaulted and will be returned after leave periods. The gateway will be removed from the network after the leave period.
_Note: Requires `signer` to be provided on `ARIO.init` to sign the transaction._
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.leaveNetwork(
// optional additional tags
{ tags: [{ name: "App-Name", value: "My-Awesome-App" }] },
);
```
#### `updateGatewaySettings({ ...settings })`
Writes new gateway settings to the callers gateway configuration.
_Note: Requires `signer` to be provided on `ARIO.init` to sign the transaction._
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.updateGatewaySettings(
{
// any other settings you want to update
minDelegatedStake: new ARIOToken(100).toMARIO(),
},
// optional additional tags

```
#### `getWithdrawals({ address, cursor, limit, sortBy, sortOrder })`
Returns every pending stake withdrawal owned by `address` — covering both operator-stake decreases (`isDelegate: false`) and delegate-stake decreases (`isDelegate: true`). A withdrawal is claimable when `Date.now() >= endTimestamp`; call `claimWithdrawal({ withdrawalId: item.vaultId })` to release the tokens.
This is the per-owner read needed to drive "you have X claimable withdrawals" UIs without fanning out across every gateway the wallet has interacted with.
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const withdrawals = await ario.getWithdrawals({
address: "9xQeWvG816bUx9EPjHmaT23yvVM2ZWbrrpZb9PusVFin",
});
const claimable = withdrawals.items.filter(
(w) => Date.now() >= w.endTimestamp,
);
```
Output

}
```
#### `increaseOperatorStake({ qty })`
Increases the callers operator stake. Must be executed with a wallet registered as a gateway operator.
_Note: Requires `signer` to be provided on `ARIO.init` to sign the transaction._
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.increaseOperatorStake(
{
qty: new ARIOToken(100).toMARIO(),
},
{
tags: [{ name: "App-Name", value: "My-Awesome-App" }],
},
);
```
#### `decreaseOperatorStake({ qty })`
Decreases the callers operator stake. Must be executed with a wallet registered as a gateway operator. Requires `signer` to be provided on `ARIO.init` to sign the transaction.
_Note: Requires `signer` to be provided on `ARIO.init` to sign the transaction._
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.decreaseOperatorStake(
{
qty: new ARIOToken(100).toMARIO(),
},
{
tags: [{ name: "App-Name", value: "My-Awesome-App" }],
},
);
```
#### `redelegateStake({ target, source, stakeQty, vaultId })`
Redelegates the stake of a specific address to a new gateway. Vault ID may be optionally included in order to redelegate from an existing withdrawal vault. The redelegation fee is calculated based on the fee rate and the stake amount. Users are allowed one free redelegation every seven epochs. Each additional redelegation beyond the free redelegation will increase the fee by 10%, capping at a 60% redelegation fee.
e.g: If 1000 mARIO is redelegated and the fee rate is 10%, the fee will be 100 mARIO. Resulting in 900 mARIO being redelegated to the new gateway and 100 mARIO being deducted back to the protocol balance.
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.redelegateStake({
target: "t4Xr0_J4Iurt7caNST02cMotaz2FIbWQ4Kbj616RHl3",
source: "HwFceQaMQnOBgKDpnFqCqgwKwEU5LBme1oXRuQOWSRA",

vaultId: "fDrr0_J4Iurt7caNST02cMotaz2FIbWQ4Kcj616RHl3",
});
```
#### `getRedelegationFee({ address })`
Retrieves the fee rate as percentage required to redelegate the stake of a specific address. Fee rate ranges from 0% to 60% based on the number of redelegations since the last fee reset.
```typescript
const ario = ARIO.init({ rpc });
const fee = await ario.getRedelegationFee({
address: "t4Xr0_J4Iurt7caNST02cMotaz2FIbWQ4Kbj616RHl3",
});
```
Output
```json
{
"redelegationFeeRate": 10,
"feeResetTimestamp": 1730996691117
}
```
#### `getAllDelegates({ cursor, limit, sortBy, sortOrder })`
Retrieves all delegates across all gateways, paginated and sorted by the specified criteria. The `cursor` used for pagination is a `cursorId` derived from delegate address and the gatewayAddress from the previous request. e.g `address_gatewayAddress`.
```typescript
const ario = ARIO.init({ rpc });
const delegates = await ario.getAllDelegates({
limit: 2,
sortBy: "startTimestamp",
sortOrder: "desc",

#### `getCostDetails({ intent, fromAddress, fundFrom, ...args})`
Calculates the expanded cost details for the interaction in question, e.g a 'Buy-Name' interaction, where args are the specific params for that interaction. The fromAddress is the address that would be charged for the interaction, and fundFrom is where the funds would be taken from, either `balance`, `stakes`, or `any`.
On Solana, the result also includes a `gasEstimate` — the total SOL (in lamports) the wallet needs to execute the intent: transaction fees (quoted from recent on-chain prioritization fees) plus rent-exempt deposits for the accounts the flow creates. For `Buy-Name` that covers both transactions (ANT spawn + buy) and the rent for the spawned asset/PDAs and the ArNS record; first-time buyers with no ACL accounts yet are quoted the ACL bootstrap rent as well (pass `fromAddress` so that check can be made). The fee side is a conservative upper bound: the write path tightens the compute-unit limit from a pre-send simulation, so the landed fee is usually lower.
```typescript
const costDetails = await ario.getCostDetails({
intent: "Buy-Name",
fromAddress: "t4Xr0_J4Iurt7caNST02cMotaz2FIbWQ4Kbj616RHl3",
fundFrom: "stakes",

```
#### `crankEpochStep(options?)`
High-level, permissionless epoch crank. Advances the epoch lifecycle by **one
step per call** and returns the action it took — run it on a loop (this is what
the standalone cranker and the observer-embedded cranker do). It owns the whole
sequence so you don't orchestrate the individual instructions yourself:
`create` → `tally` → `prescribe` → `distribute` → `close` — closing an epoch's
observation PDAs first (`close_observation`) so `close_epoch` doesn't revert —
plus an idle-tail of permissionless maintenance: `compound` delegate rewards,
`update_demand_factor`, and `prune_returned_names`. The close path is
non-wedging: a cleanup failure never blocks creation of the next epoch.
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
// one step
const result = await ario.crankEpochStep();
// → { action, epochIndex?, txId?, progress? }
// action ∈ create | tally | prescribe | distribute | close
// | close_observation | compound | update_demand_factor
// | prune_returned_names | idle
// or drive it on an interval
setInterval(async () => {
const r = await ario.crankEpochStep();
if (r.action !== 'idle') console.log(r.action, r.epochIndex, r.txId);
}, 60_000);
```
All options are optional: `batchSize`, `enableClose`, `epochRetention`,
`enableCompound`, `compoundMinPendingRewards`, `enableDemandFactorRoll`,
`enablePrune`, `pruneBatchSize`, `nameRegistryAccount`.
### Primary Names
#### `getPrimaryNames({ cursor, limit, sortBy, sortOrder })`
Retrieves all primary names paginated and sorted by the specified criteria. The `cursor` used for pagination is the last name from the previous request.
```typescript
const ario = ARIO.init({ rpc });
const names = await ario.getPrimaryNames({
cursor: "ao", // this is the last name from the previous request
limit: 1,
sortBy: "startTimestamp",
sortOrder: "desc",
});
```
Output
```json
{
"sortOrder": "desc",
"hasMore": true,
"totalItems": 100,
"limit": 1,
"sortBy": "startTimestamp",
"nextCursor": "arns",
"items": [

```typescript
const ario = ARIO.init({ rpc });
const name = await ario.getPrimaryName({
name: "arns",
});
// or
const name = await ario.getPrimaryName({
address: "t4Xr0_J4Iurt7caNST02cMotaz2FIbWQ4Kbj616RHl3",
});
```
Output
```json
{
"name": "arns",

"processId": "bh9l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM",
"startTimestamp": 1719356032297
}
```
#### `setPrimaryName({ name })`
Sets an ArNS name already owned by the `signer` as their primary name. Note: `signer` must be the owner of the `processId` that is assigned to the name. If not, the transaction will fail.
_Note: Requires `signer` to be provided on `ARIO.init` to sign the transaction._
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
await ario.setPrimaryName({ name: 'my-arns-name' });
```
#### `requestPrimaryName({ name })`
Requests a primary name for the `signer`'s address. The request must be approved by the new owner of the requested name via the `approvePrimaryNameRequest`[#approveprimarynamerequest-name-address-] API.
_Note: Requires `signer` to be provided on `ARIO.init` to sign the transaction._
```typescript
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
const { id: txId } = await ario.requestPrimaryName({
name: "arns",
});
```
#### `getPrimaryNameRequest({ initiator })`
Retrieves the primary name request for a a wallet address.
```typescript
const ario = ARIO.init({ rpc });
const request = await ario.getPrimaryNameRequest({
initiator: "t4Xr0_J4Iurt7caNST02cMotaz2FIbWQ4Kbj616RHl3",
});
```
Output
```json
{
"initiator": "t4Xr0_J4Iurt7caNST02cMotaz2FIbWQ4Kbj616RHl3",
"name": "arns",
"startTimestamp": 1728067635857,
"endTimestamp": 1735843635857
}
```
### Configuration
`ARIO.init` accepts a `@solana/kit` RPC client plus optional program ID
overrides for non-mainnet clusters. See [Networks](#networks) above for
the full shape.
## ANT Contracts
The ANT client class exposes APIs for Arweave Name Tokens. On Solana an
ANT is a Metaplex Core asset; its `processId` is the asset's mint
pubkey. The `ario-ant` program owns the on-chain records / controllers
state attached to the asset.
### Initialize
#### `init({ processId, rpc, rpcSubscriptions?, signer? })`
Factory that creates a read-only or writeable ANT client. Providing
`signer` and `rpcSubscriptions` enables write methods (`setRecord`,
`transfer`, `addController`, etc.).
```typescript
import { ANT } from '@ar.io/sdk';
import {
createSolanaRpc,
createSolanaRpcSubscriptions,
} from '@solana/kit';
const rpc = createSolanaRpc('https://api.mainnet-beta.solana.com');
// Read-only
const ant = await ANT.init({
processId: '',
rpc,
});
// Read + write
const antWrite = await ANT.init({
processId: '',
rpc,
rpcSubscriptions: createSolanaRpcSubscriptions(
'wss://api.mainnet-beta.solana.com',
),
signer,
});
```
### Spawn
#### `ANT.spawn({ rpc, rpcSubscriptions, signer, state })`
Static factory that mints a new MPL Core asset and initializes the
`ario-ant` PDAs in a single transaction. Returns
`{ processId, mint, signature }`.
```typescript
import { ANT } from '@ar.io/sdk';
const { processId, signature } = await ANT.spawn({
rpc,
rpcSubscriptions,
signer,
state: {
name: 'My ANT',
ticker: 'MYANT',
description: 'My ANT token',
uri: 'ar://',
},
});
```
**CLI Usage:**
```bash
ar.io spawn-ant \
--wallet-file wallet.json \
--name "My ANT" \
--ticker "MYANT" \
--metadata-uri "ar://"
```
**Parameters:**
- `state.name: string` — display name of the ANT
- `state.ticker?: string` — ticker symbol
- `state.description?: string` — short description
- `state.uri: string` — `ar://` URI of the Metaplex Core asset's JSON
metadata. Build via `buildAntMetadata` from `@ar.io/sdk` and upload
to Arweave (e.g. via `@ardrive/turbo-sdk`).
- `state.keywords?: string[]`
- `state.logo?: string` — Arweave TX ID of the logo
- `state.transactionId?: string` — initial `@` record target
**Returns:**
```ts
{
processId: string; // the MPL Core asset mint pubkey
mint: Address;
signature: string; // the Solana tx signature
}
```
### Versions
#### `getModuleId({ graphqlUrl?, retries? })`
Gets the module ID of the current ANT process by querying its spawn transaction tags. Results are cached after the first successful fetch.
```typescript
const moduleId = await ant.getModuleId();
console.log(`ANT was spawned with module: ${moduleId}`);
// With custom GraphQL URL and retries
const moduleId = await ant.getModuleId({
graphqlUrl: "https://turbo-gateway.com/graphql",
retries: 5,
});
```
Output
```json
"FKtQtOOtlcWCW2pXrwWFiCSlnuewMZOHCzhulVkyqBE"
```
#### `getVersion({ antRegistryId?, graphqlUrl?, retries? })`
Gets the version string of the current ANT by matching its module ID with versions from the ANT registry.
```typescript
const version = await ant.getVersion();
console.log(`ANT is running version: ${version}`);
// With custom ANT registry
const version = await ant.getVersion({
antRegistryId: "custom-ant-registry-id",
});
```
Output
```json
"23"
```
#### `isLatestVersion({ antRegistryId?, graphqlUrl?, retries? })`
Checks if the current ANT version is the latest according to the ANT registry.
```typescript
const isLatest = await ant.isLatestVersion();
if (!isLatest) {
console.log("ANT can be upgraded to the latest version");
}
```
Output
```json
true

_Note: Requires `signer` to be provided on `ANT.init` to sign the transaction._
```typescript
const { id: txId } = await ant.addController(
{ controller: "aGzM_yjralacHIUo8_nQXMbh9l1cy0aksiL_x9M359f" },
// optional additional tags
{ tags: [{ name: "App-Name", value: "My-Awesome-App" }] },
);
```
#### `removeController({ controller })`
Removes a controller from the list of approved controllers on the ANT.
_Note: Requires `signer` to be provided on `ANT.init` to sign the transaction._
```typescript
const { id: txId } = await ant.removeController(
{ controller: "aGzM_yjralacHIUo8_nQXMbh9l1cy0aksiL_x9M359f" },
// optional additional tags

);
```
### Records
#### `setBaseNameRecord({ transactionId, ttlSeconds, owner?, displayName?, logo?, description?, keywords? })`

_Note: Requires `signer` to be provided on `ANT.init` to sign the transaction._
```typescript
// get the ant for the base name
const arnsRecord = await ario.getArNSRecord({ name: "ardrive" });
const ant = await ANT.init({ processId: arnsName.processId });
// Basic usage
const { id: txId } = await ant.setBaseNameRecord({
transactionId: "432l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM",
ttlSeconds: 3600,
});
// With ownership delegation and metadata
const { id: txId } = await ant.setBaseNameRecord({
transactionId: "432l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM",
ttlSeconds: 3600,
owner: "user-wallet-address-123...", // delegate ownership to another address
displayName: "ArDrive", // display name
logo: "logo-tx-id-123...", // logo transaction ID
description: "Decentralized storage application",
keywords: ["storage", "decentralized", "web3"],
});
// ardrive.ar.io will now resolve to the provided transaction id and include metadata
```
#### `setUndernameRecord({ undername, transactionId, ttlSeconds, owner?, displayName?, logo?, description?, keywords? })`
Adds or updates an undername record for the ANT. An undername is appended to the base name of the ANT (e.g. dapp_ardrive.ar.io). Supports undername ownership delegation and metadata.
_Note: Requires `signer` to be provided on `ANT.init` to sign the transaction._
> Records, or `undernames` are configured with the `transactionId` - the arweave transaction id the record resolves - and `ttlSeconds`, the Time To Live in the cache of client applications.
```typescript
const arnsRecord = await ario.getArNSRecord({ name: "ardrive" });
const ant = await ANT.init({ processId: arnsName.processId });
// Basic usage
const { id: txId } = await ant.setUndernameRecord(
{
undername: "dapp",
transactionId: "432l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM",
ttlSeconds: 900,
},
// optional additional tags
{ tags: [{ name: "App-Name", value: "My-Awesome-App" }] },
);
// With ownership delegation and metadata

{
undername: "alice",
transactionId: "432l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM",
ttlSeconds: 900,
owner: "alice-wallet-address-123...", // delegate ownership to Alice
displayName: "Alice's Site", // display name
logo: "avatar-tx-id-123...", // avatar/logo transaction ID
description: "Personal portfolio and blog",
keywords: ["portfolio", "personal", "blog"],
},
{ tags: [{ name: "App-Name", value: "My-Awesome-App" }] },
);
// dapp_ardrive.ar.io will now resolve to the provided transaction id
// alice_ardrive.ar.io will be owned by Alice and include metadata
```
#### `removeUndernameRecord({ undername })`
Removes an undername record from the ANT process.
_Note: Requires `signer` to be provided on `ANT.init` to sign the transaction._
```typescript
const { id: txId } = await ant.removeUndernameRecord(
{ undername: "dapp" },
// optional additional tags
{ tags: [{ name: "App-Name", value: "My-Awesome-App" }] },
);
// dapp_ardrive.ar.io will no longer resolve to the provided transaction id
```
#### `setRecord({ undername, transactionId, ttlSeconds })`
> [!WARNING]
> Deprecated: Use `setBaseNameRecord` or `setUndernameRecord` instead.
Adds or updates a record for the ANT process. The `undername` parameter is used to specify the record name. Use `@` for the base name record.

);
// dapp_ardrive.ar.io will no longer resolve to the provided transaction id
```
### Metadata
#### `setName({ name })`

{ name: "My ANT" },
// optional additional tags
{ tags: [{ name: "App-Name", value: "My-Awesome-App" }] },
);
```
#### `setTicker({ ticker })`
Sets the ticker of the ANT process.
_Note: Requires `signer` to be provided on `ANT.init` to sign the transaction._
```typescript
const { id: txId } = await ant.setTicker(
{ ticker: "ANT-NEW-TICKER" },
// optional tags
{ tags: [{ name: "App-Name", value: "My-Awesome-App" }] },
);
```
#### `setDescription({ description })`

{ description: "A friendly description of this ANT" },
// optional tags
{ tags: [{ name: "App-Name", value: "My-Awesome-App" }] },
);
```
#### `setKeywords({ keywords })`

```
#### `getLogo()`
Returns the TX ID of the logo set for the ANT.
```typescript
const logoTxId = await ant.getLogo();
```
#### `setLogo({ txId })`
Sets the Logo of the ANT - logo should be an Arweave transaction ID.
_Note: Requires `signer` to be provided on `ANT.init` to sign the transaction._
```typescript
const { id: txId } = await ant.setLogo(
{ txId: "U7RXcpaVShG4u9nIcPVmm2FJSM5Gru9gQCIiRaIPV7f" },
// optional tags
{ tags: [{ name: "App-Name", value: "My-Awesome-App" }] },
);
```
### ARIO Integrations
`releaseName`, `reassignName`, `approvePrimaryNameRequest`, and
`removePrimaryNames` were AO-only orchestration helpers and have been
removed. Their on-chain equivalents on Solana live on the `ario-arns`
program and are exposed through the `ARIO` write client
(`upgradeRecord`, `setPrimaryName`, etc.) or — for permissionless
maintenance — through `SolanaARIOWriteable`'s prune helpers.
### Upgrade
#### `upgrade()`
Migrates this ANT's on-chain state to the latest schema version (per-
ANT data migration on Solana — no process forking, no name
reassignment). Returns `{ id, needsMigration }`.
```typescript
const result = await ant.upgrade();
if (result.needsMigration) {
console.log(`Migrated: ${result.id}`);
}
```
### Undername Ownership
NTs support ownership of undernames:
1. **ANT Owner** - Has full control over the ANT and all records
2. **Controllers** - Can manage records but cannot transfer ANT ownership
3. **Record Owners** - Can only update their specific delegated records
> [!WARNING]
> When a record owner updates their own record, they **MUST** include their own address in the `owner` field. If the `owner` field is omitted or set to a different address, the record ownership will be transferred or renounced.
#### `transferRecord({ undername, recipient })`
Transfers ownership of a specific record (undername) to another address. This enables delegation of control for individual records within an ANT while maintaining the ANT owner's ultimate authority. The current record owner or ANT owner/controllers can transfer ownership.
_Note: Requires `signer` to be provided on `ANT.init` to sign the transaction._
```typescript
const { id: txId } = await ant.transferRecord({
undername: "alice", // the subdomain/record to transfer
recipient: "new-owner-address-123...", // address of the new owner
});
// alice_ardrive.ar.io is now owned by the new owner address
// The new owner can update the record but not other records in the ANT
```
**CLI Usage:**
```bash
# Transfer ownership of a record using the CLI
ar.io transfer-record \
--process-id "ANT_PROCESS_ID" \
--undername "alice" \
--recipient "new-owner-address-123..." \
--wallet-file "path/to/wallet.json"
```
#### Record Owner Workflow Examples
**Checking Record Ownership:**
```typescript
const record = await ant.getRecord({ undername: "alice" });
console.log(`Record owner: ${record.owner}`);
console.log(`Transaction ID: ${record.transactionId}`);
```
**Record Owner Updating Their Own Record:**
```typescript
// Alice (record owner) updating her own record
const aliceAnt = await ANT.init({
processId: 'ANT_MINT_PUBKEY',
rpc,
rpcSubscriptions,
signer: aliceSigner, // Alice's @solana/kit signer
});
// ✅ CORRECT: Alice includes her own address as owner
const { id: txId } = await aliceAnt.setUndernameRecord({
undername: "alice",
transactionId: "new-content-tx-id-456...",
ttlSeconds: 1800,
owner: "alice-wallet-address-123...", // MUST be Alice's own address
displayName: "Alice Updated Portfolio",
description: "Updated personal portfolio and blog",
});
// ❌ WRONG: Omitting owner field will renounce ownership
const badUpdate = await aliceAnt.setUndernameRecord({
undername: "alice",
transactionId: "new-content-tx-id-456...",
ttlSeconds: 1800,
// Missing owner field - this will renounce ownership!
});
// ❌ WRONG: Setting different owner will transfer ownership
const badTransfer = await aliceAnt.setUndernameRecord({
undername: "alice",
transactionId: "new-content-tx-id-456...",
ttlSeconds: 1800,
owner: "someone-else-address-789...", // This transfers ownership to someone else!
});
```
**What Happens When Record Ownership is Renounced:**
If a record owner updates their record without including the `owner` field, the record becomes owned by the ANT owner/controllers again:
```typescript
// Before: alice record is owned by alice-wallet-address-123...
const recordBefore = await ant.getRecord({ undername: "alice" });
console.log(recordBefore.owner); // "alice-wallet-address-123..."
// Alice updates without owner field
await aliceAnt.setUndernameRecord({
undername: "alice",
transactionId: "new-tx-id...",
ttlSeconds: 900,
// No owner field = renounces ownership
});
// After: record ownership reverts to ANT owner
const recordAfter = await ant.getRecord({ undername: "alice" });
console.log(recordAfter.owner); // undefined (controlled by ANT owner again)
```
### Static Methods
`ANT.fork()` and the static `ANT.upgrade()` were AO-only (process
forking + name reassignment). On Solana, schema migration is a
per-asset CPI exposed as the instance method `ant.upgrade()` documented
above; new ANTs are created with `ANT.spawn()`.
## Escrow
Trustless, multi-protocol escrow for handing an asset to a recipient identified by
an **Arweave** or **Ethereum** address, claimable once they hold a Solana wallet.
Backed by the `ario-ant-escrow` program. Two clients:
- `TokenEscrow` — escrow liquid **ARIO** (SPL) or a **time-locked vault**.
- `ANTEscrow` — escrow an **ANT** (Metaplex Core NFT).
Each supports **deposit → claim → cancel/refund → update-recipient**. Claims work
three ways: **Arweave-attested** (an off-chain attestor re-signs the canonical
claim with Ed25519, verified on-chain), **Ethereum** (on-chain `secp256k1_recover`
+ EIP-191), and **vault** (instruction introspection that preserves the remaining
lock).
```typescript
import { TokenEscrow, canonicalMessageV2 } from '@ar.io/sdk';
const escrow = new TokenEscrow({
rpc,
rpcSubscriptions,
signer,
programId,
coreProgram,
});
// deposit 50 ARIO to an Ethereum recipient
await escrow.depositTokens({
assetId, // 32-byte client-supplied id
amount: 50_000_000n,
arioMint,
depositorTokenAccount,
recipient: { protocol: 'ethereum', publicKey: ethAddress20 },
});
// the recipient claims (Ethereum path) once they have a Solana wallet
await escrow.claimTokensEthereum({
depositor,
assetId,
claimant,
claimantTokenAccount,
escrowTokenAccount,
signature, // recipient's EIP-191 signature over canonicalMessageV2(...)
});
```
Build the exact bytes a recipient signs with `canonicalMessage` /
`canonicalMessageV2` — byte-identical to the on-chain program (and the off-chain
attestor). See the contracts repo's escrow design + protocol spec for the full
flow and the cross-language canonical-message vectors.
## Token Conversion
The ARIO process stores all values as mARIO (micro-ARIO) to avoid floating-point arithmetic issues. The SDK provides an `ARIOToken` and `mARIOToken` classes to handle the conversion between ARIO and mARIO, along with rounding logic for precision.
**All process interactions expect values in mARIO. If numbers are provided as inputs, they are assumed to be in raw mARIO values.**
#### Converting ARIO to mARIO
```typescript
import { ARIOToken, mARIOToken } from "@ar.io/sdk";
const arioValue = 1;
const mARIOValue = new ARIOToken(arioValue).toMARIO();
const mARIOValue = 1_000_000;
const arioValue = new mARIOToken(mARIOValue).toARIO();
```
## Logging
The library uses a lightweight console logger by default for both Node.js and web environments. The logger outputs structured JSON logs with timestamps. You can configure the log level via `setLogLevel()` API or provide a custom logger that satisfies the `ILogger` interface.
#### Default Logger
```typescript
import { Logger } from "@ar.io/sdk";
// set the log level
Logger.default.setLogLevel("debug");
// Create a new logger instance with a specific level
const logger = new Logger({ level: "debug" });
```
#### Custom Logger Implementation
You can provide any custom logger that implements the `ILogger` interface:
```typescript
import { ARIO, ILogger } from "@ar.io/sdk";
// Custom logger example
const customLogger: ILogger = {
info: (message, ...args) => console.log(`[INFO] ${message}`, ...args),
warn: (message, ...args) => console.warn(`[WARN] ${message}`, ...args),
error: (message, ...args) => console.error(`[ERROR] ${message}`, ...args),
debug: (message, ...args) => console.debug(`[DEBUG] ${message}`, ...args),
setLogLevel: (level) => {
/* implement level filtering */
},
};
// Set it as the default logger across the entire SDK — every class
// (ARIO, ANT, ANTRegistry, etc.) will route logs through it. `ARIO.init`
// does not accept a per-instance logger.
Logger.default = customLogger;
```
## Pagination
#### Overview
Certain APIs that could return a large amount of data are paginated using cursors. The SDK uses the `cursor` pattern (as opposed to pages) to better protect against changing data while paginating through a list of items. For more information on pagination strategies refer to [this article](https://www.getknit.dev/blog/api-pagination-best-practices#api-pagination-techniques-).
Paginated results include the following properties:
- `items`: the list of items on the current request, defaulted to 100 items.
- `nextCursor`: the cursor to use for the next batch of items. This is `undefined` if there are no more items to fetch.
- `hasMore`: a boolean indicating if there are more items to fetch. This is `false` if there are no more items to fetch.
- `totalItems`: the total number of items available. This may change as new items are added to the list, only use this for informational purposes.
- `sortBy`: the field used to sort the items, by default this is `startTimestamp`.
- `sortOrder`: the order used to sort the items, by default this is `desc`.
To request all the items in a list, you can iterate through the list using the `nextCursor` until `hasMore` is `false`.
```typescript
let hasMore = true;
let cursor: string | undefined;
const gateaways = [];
while (hasMore) {
const page = await ario.getGateways({ limit: 100, cursor });
gateaways.push(...items);
cursor = page.nextCursor;
hasMore = page.hasMore;
}
```
#### Filtering
Paginated APIs also support filtering by providing a `filters` parameter. Filters can be applied to any field in the response. When multiple keys are provided, they are treated as AND conditions (all conditions must match). When multiple values are provided for a single key (as an array), they are treated as OR conditions (any value can match).
Example:
```typescript
const records = await ario.getArNSRecords({
filters: {
type: "lease",
processId: [
"ZkgLfyHALs5koxzojpcsEFAKA8fbpzP7l-tbM7wmQNM",
"r61rbOjyXx3u644nGl9bkwLWlWmArMEzQgxBo2R-Vu0",
],
},
});
```
In the example above, the query will return ArNS records where:
- The type is "lease" AND
- The processId is EITHER "ZkgLfyHALs5koxzojpcsEFAKA8fbpzP7l-tbM7wmQNM" OR "r61rbOjyXx3u644nGl9bkwLWlWmArMEzQgxBo2R-Vu0"
## Advanced
### RPC Configuration
The SDK accepts any `@solana/kit` RPC client. For read-only usage, only
`rpc` is required. Write operations additionally need `rpcSubscriptions`
(WebSocket) for transaction confirmation and a `signer`.
#### Basic (read-only)
```ts
import { ARIO } from '@ar.io/sdk';
import { createSolanaRpc } from '@solana/kit';
const rpc = createSolanaRpc('https://api.mainnet-beta.solana.com');
const ario = ARIO.init({ rpc });
```
#### With writes (signer + WebSocket subscriptions)
```ts
import { ARIO } from '@ar.io/sdk';
import {
createSolanaRpc,
createSolanaRpcSubscriptions,
createKeyPairSignerFromBytes,
} from '@solana/kit';
const rpc = createSolanaRpc('https://api.mainnet-beta.solana.com');
const rpcSubscriptions = createSolanaRpcSubscriptions(
'wss://api.mainnet-beta.solana.com',
);
const signer = await createKeyPairSignerFromBytes(/* ... */);
const ario = ARIO.init({ rpc, rpcSubscriptions, signer });
```
> **Note:** `rpcSubscriptions` opens a WebSocket connection and is only
> needed for writes. If your RPC provider doesn't expose a WebSocket
> endpoint, omit it and use the SDK in read-only mode.
### Circuit Breaker
The SDK ships an [opossum]-backed circuit breaker that wraps the RPC
transport. When the primary endpoint starts failing (429 rate-limits,
5xx errors, network timeouts) the circuit opens and subsequent calls
route transparently to a fallback RPC until the primary recovers.
```ts
import { ARIO, createCircuitBreakerRpc } from '@ar.io/sdk';
const rpc = createCircuitBreakerRpc({
primaryUrl: 'https://my-premium-rpc.example.com',
fallbackUrl: 'https://api.mainnet-beta.solana.com',
});
const ario = ARIO.init({ rpc });
```
Use `defaultFallbackUrl()` to auto-pick mainnet or devnet based on the
primary URL:
```ts
import {
createCircuitBreakerRpc,
defaultFallbackUrl,
} from '@ar.io/sdk';
const primaryUrl = 'https://my-premium-rpc.example.com';
const rpc = createCircuitBreakerRpc({
primaryUrl,
fallbackUrl: defaultFallbackUrl(primaryUrl), // → mainnet public RPC
});
```
Tuning knobs (all optional):
| Option | Default | Description |
|---|---|---|
| `timeout` | `10000` | ms before a single request is timed out (`false` to disable) |
| `errorThresholdPercentage` | `50` | error % at which to open the circuit |
| `resetTimeout` | `30000` | ms to wait before probing the primary again (half-open) |
| `volumeThreshold` | `5` | minimum requests in the rolling window before the circuit can trip |
### Automatic Retries
All RPC **read** calls (account fetches, `getProgramAccounts`, etc.)
automatically retry on transient transport errors with exponential
back-off. Writes are **not** retried (to avoid double-sends).
Retried errors: HTTP 429/5xx, `fetch failed`, `ECONNRESET`,
`ETIMEDOUT`, `AbortError` / timeouts. Non-retryable errors (account
not found, invalid params, deserialization) throw immediately.
Defaults: **6 attempts**, 500 ms base delay, 5 s max delay. Override
per-call with the exported `withRetry` helper:
```ts
import { withRetry } from '@ar.io/sdk';
const result = await withRetry(() => rpc.getAccountInfo(addr).send(), {
maxAttempts: 3,
baseDelayMs: 1000,
});
```
### Generated instruction builders
For custom transaction building, import Codama-generated typed clients
from [`@ar.io/solana-contracts`](https://www.npmjs.com/package/@ar.io/solana-contracts):
```ts
import {
getBuyNameInstructionAsync,
ARIO_ARNS_PROGRAM_ADDRESS,
} from '@ar.io/solana-contracts/arns';
```
### Networks
| Network | RPC | Programs |
|---|---|---|
| Mainnet | `https://api.mainnet-beta.solana.com` (mainnet-beta, default) | Not yet deployed — placeholder IDs in `src/solana/constants.ts` |
| Devnet | `https://api.devnet.solana.com` | See `src/solana/constants.ts` for current devnet program IDs |
| Localnet | Surfpool — `https://github.com/solana-foundation/surfpool` | Localnet harness in `solana-ar-io` monorepo |
The migration tooling (snapshot exporter, batch importer, claim app)
lives in the [`solana-ar-io`](https://github.com/ar-io/solana-ar-io)
monorepo until cutover.
## Resources
### Bundling
