# SignAndSendTransaction

Once an application is connected to Broearn Wallet, it can prompt the user for permission to send transactions on their behalf.

In order to send a transaction, an application must:

1\. Create an unsigned transaction.\
2.Have the transaction be signed and submitted to the network by the user's Broearn Wallet.\
3.Optionally await network confirmation using a PUT JSON RPC connection.
