Overview

A signer backed by an Ed25519 key pair, capable of signing both transaction messages and off-chain messages.

Mirrors TypeScript’s ‘KeyPairSigner<TAddress>`, which combines MessagePartialSigner and TransactionPartialSigner with a CryptoKeyPair reference.

In Ruby we keep it simple: the signer holds an RbNaCl::SigningKey (which contains the private key seed and can derive the public key) and exposes the signer’s address.
