I'd like to generate and sign a transaction offline and then send that transaction with a different account. I've found a few web3js sources and I've read the web3 documentation, but I haven't found any clear solutions for doing this in Java with web3j. Thanks for the help.
I think something like this should work
// Create the Transaction RawTransaction rawTransaction = RawTransaction.createEtherTransaction(<nonce>, <gasPrice>, <gasLimit>, <to>, <value>); // Sign the Transaction byte signedMessage = TransactionEncoder.signMessage(rawTransaction, <your-Credentials>); String hexValue = Numeric.toHexString(signedMessage);
and then give the hexValue to the third-party to broadcast it to the network
