如何在 Web3j 中的 infura 上使用凭证钱包路径和元掩码帐户

Question

Web3j web3 = Web3j.build(new HttpService()); // defaults to http://localhost:8545/ Credentials credentials = WalletUtils.loadCredentials("password", "/path/to/walletfile");

1. How to connect rinkeby network using Web3j.

2. I try to change "/path/to/walletfile" by a private key of metamask account. Without success.

How can I make it works? Thx.

Answer 1

An easy way to do this is using your private key. In metamask click "account details" and "export private key".

Then use Credentials.create("YourPrivateKey")
