Thanks, I’ve seen these topics already. I think, you directed me to this piece of code on https://docs.moralis.io/web3
const web3 = await Moralis.Web3.enable(); const contract = new web3.eth.Contract(contractAbi, contractAddress);
It’s not actually what I want to invoke, but later I will try to call a smart contract method too (the way shown in the Moralis Web3 docs).
Well, I hope that after the crypto login with Metamask the logined EthAddress becomes unlocked, so I will be able to use the web3.eth.signTransaction => web3.eth.sendSignedTransaction. Will give that a try.
