1. How to get web3WalletAccountKey and web3WalletEVMAddress ?

Please open Safeheron Web Console, choose an Web3 wallet which you want to use, click to go to wallet detail page, then you will see a link like https://www.safeheron.com/console/wallet/account58xxxxcbf34_web3 in your browser address bar, the account58xxxxcbf34 string without _web3 suffix is your web3 account key. And you can also copy your Web3 EVM address at the top of this page.
