A React ̶+̶ ̶R̶e̶d̶u̶x̶ library for fetching, batching, and caching chain state via the MultiCall contract.
yarn add @nftearth/uniswap-multicall or npm install @nftearth/uniswap-multicall
The usage of this library is similar to RTK Query.
import { MulticallProvider } from '@nftearth/uniswap-multicall'
reactDOM.render(
<MulticallProvider />
)To use the provider, 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 UniswapInterfaceMulticallFor a more detailed example, see basic example app in ./integration-tests
The latest version of the SDK is used in production in the Uniswap Interface,
but it is considered Alpha software and may contain bugs or change significantly between patch versions.
