xxjjyy 基于区块链的毕业设计Etherplex – 以太丛
本文提供基于区块链的毕业设计国外最新区块链项目源码下载，包括solidity,eth,fabric等blockchain区块链,基于区块链的毕业设计Etherplex – 以太丛 是一篇很好的国外资料
Etherplex
Ethers.js + Multicall
Batch multiple Ethereum JSON RPC calls into a single RPC call.
Features:
- Uses the Multicall contract when available
- Falls back to individual RPC requests when not available
Setup
$ yarn add @pooltogether/etherplex
Usage
- First create a contract wrapper using the
contractfunction - Chain calls on the contract and pass the results into the
batchfunction
import { ethers } from 'ethers' import { batch, contract } from '@pooltogether/etherplex' // Assuming ERC20Abi is an ABI // Assume the DAI_ADDRESS and USDC_ADDRESS constants are Ethereum addresses let daiContract = contract('Dai', ERC20Abi, DAI_ADDRESS) // Alternatively, you can just pass in an ethers.Contract instance let ethersContract = new ethers.Contract(USDC_ADDRESS, ERC20Abi, provider) let usdcContract = contract('Usdc', ethersContract) let results = await batch( ethers.getDefaultProvider(), daiContract .balanceOf(address) .totalSupply(), usdcContract .balanceOf(address) .totalSupply() ) /* Will yield: { Dai: { 'balanceOf(address)': [BigNumber], balanceOf: [BigNumber], }, Usdc: { 'balanceOf(address)': [BigNumber], balanceOf: [BigNumber], } } */
* add mumbai multicall address to etherplex
