# Aurora Relayer v2
[](https://creativecommons.org/publicdomain/zero/1.0/)
[](https://discord.gg/jNjHYUF8vw)
Web3-compatible relayer server for Aurora, implements;
* a JSON-RPC server compatible with Ethereum's [Web3 API] for [Aurora Engine] instances deployed on the NEAR Protocol.
* an indexer which continuously reads JSON files generated by [Aurora Refiner] and populate local embedded storage
**This document is useful for developers, contributors and those who would like to build, run and experiment Aurora Relayer v2 natively.
For packaged releases please see the distribution project [Standalone Aurora Relayer and Refiner] which containerizes and packs [Aurora Relayer v2] and [Aurora Refiner] for end users**
## Prerequisites and Dependencies
* requires [Go] and [Make] to build from source
* requires a NEAR account and signing key to start relayer, see [Configuration]
* requires JSON files, generated by [Aurora Refiner], to index blocks
* depends on [Aurora Relayer v2 Base] library which provides common functionality for public and private Aurora Relayer implementations
## How To Build
```bash
git clone https://github.com/aurora-is-near/relayer2-public.git
cd relayer2-public
make
```
build artifacts are placed in `out` directory
* relayer executable
* config directory
* build.info file
## How To Use
Relayer requires a set of configuration files to start (see [Configuration] for details), and default configuration files for `mainnet` and `testnet` are
provided under `config` directory after build process. If config file path is not specified, Relayer starts with `config/testnet.yaml`
by default.
### Configuring a signing key
To be able to call `eth_sendRawTransaction`, you must have a NEAR account and
signing key on the network you are relaying to, and said NEAR account must have
a sufficient Ⓝ balance to be able to send transactions.
For those who prefer not to use personal accounts, a new signing key can be generated.
#### Setting the Signer Key Location
Ensure the signer key location is defined in the configuration file:
Ex. :
```yaml
endpoint:
...
engine:
...
signerKey: config/relayer.json
```
#### Generating the Signer Key
Execute the following command to generate a new signer key:
```bash
./relayer generate-key
```
> Note: The default configuration file used is config/testnet.yaml.
Upon successful execution, a `relayer.json` file will be generated. An example of its structure is as follows:
```json
{
"account_id": "703f78e5355ae6fedf6384257a18e4cfb55bada321f6e7a35b1e21a3803b03e0",
"public_key": "ed25519:8ZAoFCzzj7FwADapMyRCctau295MpvKT5Y1z6cPySCko",
"secret_key": "ed25519:3j8Rxcnx6BcVvphxJpxKMJGWDfjTrSZTvDx7EdWm7L223dwkK8ZgebXieiadAZ3v5Xfg9AKx4XYsaPPcfmncFNo1"
}
```
Update the configuration file's `signer` field with the `account_id` value from the generated `relayer.json` file:
```yaml
endpoint:
...
engine:
...
signer: 703f78e5355ae6fedf6384257a18e4cfb55bada321f6e7a35b1e21a3803b03e0
signerKey: config/relayer.json
```
#### Activating implicit account
In the NEAR Protocol, implicit accounts require activation. This is achieved when a contract-based account or an externally-owned account transfers funds to the implicit account. This step is crucial as the signer account balance is utilized to cover the costs for `eth_sendRawTransaction`. Utilize any NEAR-compatible wallet or the [near send] command. Below is an example that transfers 0.5 NEAR to the generated account:
```bash
near send myaccount.near 703f78e5355ae6fedf6384257a18e4cfb55bada321f6e7a35b1e21a3803b03e0 0.5
```
### Handling Multiple Access Keys
When dispatching multiple transactions concurrently, each signed by a different EOA, you may encounter the `ERR_INCORRECT_NONCE` error. The solution is for the relayer to use multiple access keys, signing each transaction with a distinct key.
#### Generating Multiple Keys
After [configuring and activating the access key](#configuring-a-signing-key), execute the following:
```bash
./relayer add-keys --config config/mainnet.yaml -n 100
```
This command generates 100 keys, storing them in the same directory as the `config/relayer.json` file. Upon restarting, the relayer will leverage these access keys for transaction signing.
#### Removing Keys
To delete these keys from the account, run:
```bash
./relayer delete-keys --config config/mainnet.yaml
```
You can also use ENV variables to configure the signing account and private key:
#### Mainnet
```bash
export AURORA_RELAYER_ENDPOINT_ENGINE_SIGNER= # or set in config/mainnet.yaml
export AURORA_RELAYER_ENDPOINT_ENGINE_SIGNERKEY= # or set in config/mainnet.yaml
./relayer start --config config/mainnet.yaml
```
#### Testnet
```bash
export AURORA_RELAYER_ENDPOINT_ENGINE_SIGNER= # or set in config/testnet.yaml
export AURORA_RELAYER_ENDPOINT_ENGINE_SIGNERKEY= # or set in config/testnet.yaml
./relayer start # default config file is config/testnet.yaml
```
If you're using the [NEAR CLI], you will find your signing keys stored as JSON
key files under your `$HOME/.near-credentials/` directory.

## Versioning
* `2.0.0` is the initial version of [Aurora Relayer v2]
* [Aurora Relayer v1] is being deprecated, and not source code compatible with this version.
* We are following Go lang's practices and applying semantic versioning `vMAJOR[.MINOR[.PATCH[-PRERELEASE][+BUILD]]]`
* `MAJOR` indicates backward incompatibility
* `MINOR` backward compatible and stable release with new features and/or bug fixes
* `PATCH` backward compatible and stable release for hot-fixes published out of planned release cycle
* `PRERELEASE` does not guarantees stability, mostly used for QA cycles, e.g.: `alpha`, `beta` with optional build number
## Migration
### from v2.0.x to v2.1.x
Relayer2-Public v2.1.0 introduces a new JSON-RPC server. Therefore, for those who already have a native Relayer2-Public with version
`v2.0.x` should update the configuration .yaml file accordingly.
#### sample v2.0.x config.yaml
```shell
rpcNode:
geth: # -> deprecated
HTTPHost: localhost
HTTPPort: 8545
HTTPPathPrefix: ""
HTTPCors:
- "*"
HTTPVirtualHosts: # -> deprecated
- "*"
HTTPModules: # -> deprecated
- "net"
- "web3"
- "eth"
- "parity"
WSHost: localhost
WSPort: 8545
WSPathPrefix: ""
WSModules: # -> deprecated
- "net"
- "web3"
- "eth"
- "parity"
```
#### sample v2.1. config.yaml
```shell
rpcNode:
httpHost: localhost
httpPort: 8545
httpPathPrefix: "*"
httpCors:
- "*"
httpCompress: true # -> new subfield
httpTimeout: 300 # -> new subfield
wsHost: localhost
wsPort: 8545
wsPathPrefix: "*"
wsHandshakeTimeout: 10 # -> new subfield
maxBatchRequests: 1000 # -> new subfield
```
**IMPORTANT** Please note that configuration update step is automatically done if you are
using distribution project [Standalone Aurora Relayer and Refiner].
