MultiCall
A React + Redux library for fetching, batching, and caching chain state via the MultiCall contract.
Setup
yarn add @uniswap/redux-multicall
or npm install @uniswap/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 Uniswap Multicall2 contract:
import { abi as MulticallABI } from '@uniswap/v3-periphery/artifacts/contracts/lens/UniswapInterfaceMulticall.sol/UniswapInterfaceMulticall.json'
import { Contract } from '@ethersproject/contracts'
import { UniswapInterfaceMulticall } from './abi/types'
const multicall2Contract = new Contract(address, MulticallABI, provider) as UniswapInterfaceMulticall
For a more detailed example, see basic example app in ./integration-tests
