       description: If your module tracks nonces per signature (e.g., to prevent replay attacks), this is the unique nonce to use for the signature. It should be an unsigned 64-bit integer in big-endian format. It must be between 0 and 2^64-2, inclusive. If your module doesn't use nonces, we suggest setting this to 2^64-1 instead of 0 because 0 is a legal nonce and will cause complications with your module if you ever want to use a nonce in the future.
