deno-eth-create2-calculator

Deno port of eth-create2-calculator

This library calculates the create2 address of any given deploy code and from address. It works similar to [ethers.utils.getCreate2Address], but allows to pass in the full byte code and constructor arguments seperately.

This library is a stripped down version from thegostep/solidity-create2-deployer

API

import { calculateCreate2 } from 'npm:[email protected]'

calculateCreate2(from, salt, byteCode [, constructorArguments]) // constructorArguments is optional, byteCode can have already the constructor arguments attached
> '0x12345...' // calculated contract address

Examples

Dummy data

// example contract data for deployment
