The easiest and most recommended way to send a transaction is via SignAndSendTransaction. It is safer for users, and a simpler API for developers, for Broearn Wallet to submit the transaction immediately after signing it instead of relying on the application to do so.

However, it is also possible for an app to request just the signature from Broearn Wallet. Once signed, an app can submit the transaction itself .
