domain_account_abstraction_ed25519_hex - [mainnet]

Domain account abstraction using ed25519 hex for signing.

Authentication takes digest, converts to hex (prefixed with 0x, with lowercase letters), and then expects that to be signed. authenticator is expected to be signature: vector account_identity is raw public_key.
