Building the transactions and wallet flow

I have created the wallets and transasction flow signs a message built from the transaction’s own contents using the sender’s private key. Basically newtransaction part of the code. Verify checks that signature against the sender’s public key. Change any field amount, recipient after signing, and Verify returns false, because the signature no longer matches the (now different) message.
