Step 3: Set up automatic transaction signing

Once a transaction is successfully verified and accepted, a final signature is required before broadcasting it to the blockchain.

During the initial setup, run this API with the action parameter set to start to enable automatic signing and execution of approved transactions. After setup, the system will automatically process future transactions for signing and broadcasting.
