# Curve JS
## Setup
Install from npm:
`npm install @curvefi/api`
## Init
```ts
import curve from "@curvefi/api";
(async () => {
// 1. Dev
await curve.init('JsonRpc', {url: 'http://localhost:8545/', privateKey: ''}, { gasPrice: 0, maxFeePerGas: 0, maxPriorityFeePerGas: 0, chainId: 1 });
// OR
await curve.init('JsonRpc', {}, {}); // In this case JsonRpc url, privateKey, fee data and chainId will be specified automatically
// 2. Infura
await curve.init("Infura", { network: "homestead", apiKey: }, { chainId: 1 });
// 3. Web3 provider
await curve.init('Web3', { externalProvider: }, { chainId: 1 });
// Fetch factory pools
await curve.factory.fetchPools();
await curve.crvUSDFactory.fetchPools();
await curve.EYWAFactory.fetchPools();
await curve.cryptoFactory.fetchPools();
await curve.twocryptoFactory.fetchPools();
await curve.tricryptoFactory.fetchPools();
await curve.stableNgFactory.fetchPools();
})()
```
**Note 1.** ```chainId``` parameter is optional, but you must specify it in the case you use Metamask on localhost network, because Metamask has that [bug](https://hardhat.org/metamask-issue.html)
**Note 2.** Web3 init requires the address. Therefore, it can be initialized only after receiving the address.
**Wrong ❌️**
```tsx
import type { FunctionComponent } from 'react'
import { useState, useMemo } from 'react'
import { providers } from 'ethers'
import Onboard from 'bnc-onboard'
import type { Wallet } from 'bnc-onboard/dist/src/interfaces'
import curve from '@curvefi/api'
...
const WalletProvider: FunctionComponent = ({ children }) => {
const [wallet, setWallet] = useState()
const [provider, setProvider] = useState()
const [address, setAddress] = useState()
const networkId = 1
const onboard = useMemo(
() =>
Onboard({
dappId: DAPP_ID,
networkId,
subscriptions: {
address: (address) => {
setAddress(address)
},
wallet: (wallet) => {
setWallet(wallet)
if (wallet.provider) {
curve.init("Web3", { externalProvider: wallet.provider }, { chainId: networkId })
}
},
},
walletSelect: {
wallets: wallets,
},
}),
[]
)
...
```
**Right ✔️**
```tsx
import type { FunctionComponent } from 'react'
import { useState, useMemo, useEffect } from 'react'
import { providers } from 'ethers'
import Onboard from 'bnc-onboard'
import type { Wallet } from 'bnc-onboard/dist/src/interfaces'
import curve from '@curvefi/api'
...
const WalletProvider: FunctionComponent = ({ children }) => {
const [wallet, setWallet] = useState()
const [provider, setProvider] = useState()
const [address, setAddress] = useState()
const networkId = 1
const onboard = useMemo(
() =>
Onboard({
dappId: DAPP_ID,
networkId,
subscriptions: {
address: (address) => {
setAddress(address)
},
wallet: (wallet) => {
setWallet(wallet)
},
},
walletSelect: {
wallets: wallets,
},
}),
[]
)
useEffect(() => {
if (address && wallet?.provider) {
curve.init("Web3", { externalProvider: wallet.provider }, { chainId: networkId })
}
}, [address, wallet?.provider]);
...
```
## Notes
- 1 Amounts can be passed in args either as numbers or strings.
- 2 depositOrWithdraw**Bonus** and swap**PriceImpact** methods return %, e. g. 0 < bonus/priceImpact <= 100
- 3 Slippage arg should be passed as %, e. g. 0 < slippage <= 100

## Gas estimation
Every non-constant method has corresponding gas estimation method. Rule: ```obj.method -> obj.estimateGas.method```
**Examples**
```ts
import curve from "@curvefi/api";
(async () => {
await curve.init('JsonRpc', {}, { gasPrice: 0, maxFeePerGas: 0, maxPriorityFeePerGas: 0 });
const spender = "0xbEbc44782C7dB0a1A60Cb6fe97d0b483032FF1C7" // 3pool swap address
await curve.estimateGas.ensureAllowance(["DAI", "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"], [1000, 1000], spender);
// 94523
const pool = curve.getPool('usdn');
await pool.estimateGas.depositApprove(["1000", "1000", "1000", "1000"]);
// 186042
await pool.estimateGas.deposit(["1000", "1000", "1000", "1000"]);
// 679238
await curve.router.estimateGas.swap('DAI', "WBTC", "1000");
// 476904
await curve.boosting.estimateGas.createLock('1000', 365);
// 324953
})()
```
## Gas estimation L2
**Only for OPTIMISM and BASE!**
Arbitrium is also L2 network, but for estimateGas should use default method `estimateGas`, which return `Number`.
For L2 networks `estimateGas` return array `[L2GasUsed, L1GasUsed]`, where `L2GasUsed` - gas estimate for execution transaction in current L2 network, and `L1GasUsed` - gas estimate for data storage in parent L1 network.
Gas Price in L1 is required to calculate the fee.
You can use `getGasPriceFromL1` for get Gas Price in L1.
````ts
const L1GasPrice = await curve.getGasPriceFromL1()
// 23348207475
````
**Calculate fee**
`fee = L2GasUsed*L2GasPrice + L1GasUsed*L1GasPrice`
For OP and Base networks you can get `L2GasPrice` from `curve.getGasPriceFromL2`
````ts
const L2GasPrice = await curve.getGasPriceFromL2()
// 13161051
````
## Factory
### Fetch new pools from blockchain
```ts
import curve from "@curvefi/api";
(async () => {
await curve.init('JsonRpc', {}, { gasPrice: 0 });

await curve.factory.fetchPools();
await curve.crvUSDFactory.fetchPools();

await curve.cryptoFactory.fetchPools();

await curve.tricryptoFactory.fetchPools();
await curve.stableNgFactory.fetchPools();
// Fetch very new pools (that haven't been added to api yet) from blockchain
await curve.factory.fetchNewPools();
// [ 'factory-v2-285' ]
await curve.cryptoFactory.fetchNewPools();
