can
Returns whether this adapter can produce an Ed25519 signature for the given verifier-contract address and public-key pair.
Called before the in-memory keypair registry is consulted. When this method returns true, the adapter must be able to fulfil a subsequent signAuthDigest call for the same key without error.
Return
true when the adapter can sign for this (verifierAddress, publicKey) pair.
Parameters
verifier
The C-strkey of the Ed25519 verifier contract identifying the on-chain signer slot.
public
The 32-byte Ed25519 public key identifying the signer slot.
