ethers-multicall
⚡🚀 Call multiple view functions, from multiple Smart Contracts, in a single RPC query!
Querying an RPC endpoint can be very costly (100+ queries) when loading data from multiple smart contracts.
With multicall, batch these queries into a single, on-chain query, without additional over-head!
This is the standalone package of the library formerly created & used by Zapper.
Install
npm install ethers-multicall
yarn add ethers-multicall
Usage
import { ethers } from "ethers";
import { EthersMulticall } from "@morpho-labs/ethers-multicall";
const provider = new ethers.providers.JsonRpcBatchProvider("...");
const multicall = new EthersMulticall(provider);
const uni = multicall.wrap(
new ethers.Contract("0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984", UniswapAbi)
);
Promise.all([uni.name(), uni.symbol(), uni.decimals()]).then(console.log);
