The rpc wrapper is a wrapper around evm based rpc. It allows you as an developer not to handle retrying, logging and performance monitoring of your rpcs.

Getting started

The package is available as an NPM package

You can install the package by running

> yarn add @lifi/rpc-wrapper

or if you use npm

> npm install @lifi/rpc-wrapper

Since the RPCProvider extends the ethersproject Fallbackprovider you can easily swap out your rpc handling with the RPCProvider.

// specify your rpc providers for your specific chain
const myRpcProviders = ['https://rpc1.com', 'https://rpc2.com']
// initialize the rpc provider
const provider = new RPCProvider(myRpcProviders)

const blockNumber = provider.getBlockNumber()
console.log('This is a block number ', blockNumber)
