is the simplest and most recommended method for sending a transaction. Solflare submitting the transaction immediately after signing is safer for users and a simpler API for developers than relying on the application to do so.

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