publicKey property
The public key of the signer (32 bytes), for asking TWMessageSignerPreImageHashes for
the bytes to sign without holding the secret — the external-signing flow, where the key
lives in a hardware wallet. MessageType_offchain_v0 states the signer inside the signed
bytes, so its pre-image cannot be built without one of the two keys; MessageType_raw
needs neither. Ignored when signing, which takes the signer from private_key.
Implementation
@$pb.TagNumber(6)
$core.List<$core.int> get publicKey => $_getN(5);
