eth-deploy-crosschain

eth-deploy-crosschain

This library create a raw transaction to deploy contracts at the same address on different EVM chains. This method is known as Nick's method.

1. We generate a transaction from a new random account. This transaction MUST NOT use EIP-155 in order to work on any chain. This transaction MUST have a relatively high gas price to be deployed on any chain. Default is 200 GWEI. The gas limit should be chosen, to be just enough to deploy the contract, otherwise you would need to over-fund the deployer address.
2. We replace the r, s values with 0x1234... and v with 27. This signs by a random address of which nobody knows the private key.
3. We recover the signer from the raw transaction to get the deployer address.
4. We send sufficient native coins of the blockchain to the account, and send the raw transaction (e.g. using web3.eth.sendSignedTransaction(rawTx))
5. The contract deploys at the fixed address, and the same rawTransaction can be used on other EVM blockchains, by repeating step 4.

NOTE: The gas limit should be chosen, to be just enough to deploy the contract, otherwise you would need to over-fund the deployer address.

Other useful tools by me:

• eth-create2-calculator

Usage

npm

$ npm install eth-deploy-crosschain

API

import { generateCrossChainTransaction } from 'eth-deploy-crosschain'

generateCrossChainTransaction(byteCode [, options])
> {
    deployerAddress: '0xaccountToFund',
    contractAddress: '0xcontractAddress', // this contract address can be deployed on many EVM chains
    rawTransaction: '0xrawTransaction...'
}

The optional options object structure:

options = {
    gas: Number, // default: 4000000 // Set this yourself!! The gas limit should be chosen, to be just enough to deploy the contract, otherwise you would need to over-fund the deployer address.
    gasPrice: String, // default: 200 GWEI (200000000000) // gas price in WEI, should be choosen high enough, as this transaction might not be able to be used in with future gasprices, and on other chains.
    constructorArgs: {
        params: [value],
        types: [type] // can be a solidty type (`address`, `bytes32`, `string`, `uint256`, etc)
    },
}
