MultiCall

A React + Redux library for fetching, batching, and caching chain state via the MultiCall contract.

Setup

yarn add @moraswap/redux-multicall or npm install @moraswap/redux-multicall

Usage

The usage of this library is similar to RTK Query.

// Somewhere in your app
export const multicall = createMulticall({ reducerPath: 'multicall' })

// In your store's root reducer
export const rootReducer = combineReducers({
  // Other reducers
  [multicall.reducerPath]: multicall.reducer
})

To use the updater, you'll need an instance of the Moraswap Multicall2 contract:

import { abi as MulticallABI } from '@moraswap/v3-core/artifacts/contracts/lens/MoraswapInterfaceMulticall.sol/MoraswapInterfaceMulticall.json'
import { Contract } from '@ethersproject/contracts'
import { MoraswapInterfaceMulticall } from './abi/types'

const multicall2Contract = new Contract(address, MulticallABI, provider) as MoraswapInterfaceMulticall

For a more detailed example, see basic example app in ./integration-tests
