Class: OvercastProtocolSigner
Defined in: packages/overcast-core/src/protocol-signer.ts:54
Signs protocol payloads — not chain transactions. Where an OvercastChainSigner turns a built transaction into an on-chain result, a protocol signer produces a detached signature over an Operation's digest, used for the protocol's off-chain authorization (e.g. authorizing an offer).
The protocol fixes the signing scheme to the ed25519 curve and it is not
chain-specific, so this lives in core outside any settlement layer or
ProtocolFactory: createProtocolSigner builds one straight from
the OvercastConfig (its privateKey). Supply
["protocolSigner"] to plug in your own instead.
This is only the key — the account it signs on behalf of (an operation's
creator) is the app-wide OvercastApp.owner. The two match for a
self-custodied signer; a delegate signer (e.g. a KMS key authorized via
key add) signs with its own key for someone else's wallet.

Methods
signOperation()
signOperation(op): Promise<SignedOperation>;
Defined in: packages/overcast-core/src/protocol-signer.ts:72
Sign a whole Operation. The digest and envelope are the operation's business, so this just hands itself over — every RawSigner implementation gets it for free.
