Keystore

The relay features built-in keystore functionality. This allows the relay to sign transactions and messages without the need for an external keystore. The relay keystore is encrypted using a password and stored in a file.

The passowrd is stored and encrypted using AWS KMS.

The KMS guide can be found on KMS section.
