There’s a number of questions and answers about calling contract methods via web3, but they are either outdated (i.e. for web3 0.x while 1.x has many breaking changes) and/or don’t include signing (1, 2, 3). The first steps, as far as I understand, should be these:
import Web3 from "web3" import { AbiItem } from "web3-utils" ;(async() => { const provider = new Web3.providers.HttpProvider(...) const web3 = new Web3(provider) // see https://ethereum.stackexchange.com/a/98149/40080 and https://github.com/ChainSafe/web3.js/issues/3310#issuecomment-997396686 const abi = ... as AbiItem[] // imported from a file const methodName = ... const callParameters = [ ... ] const contractAddress = ... const universeContract = new web3.eth.Contract(abi, contractAddress) const call = universeContract.methods[methodName](callParameters) })() but then I also have to sign this with private key and send, and this is what I haven’t achieved yet. According to this answer, I should be using eth.accounts.sign(data, privateKey) (since I have to do this without a node), but I have no idea what data I should extract from call and how (and how to further send it). Can somebody show how to do this or at least give some pointers?
