Interface: OvercastProtocolSigner

Defined in: packages/overcast-core/src/protocol-signer.ts:20

Signs arbitrary 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 raw bytes, 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: createProtocolSigner builds one in core straight from the OvercastConfig (its privateKey), so it lives outside any settlement layer or ProtocolFactory. Supply OvercastConfig.protocolSigner to plug in your own implementation (e.g. a remote / HSM signer) instead.

Properties

The signer's public key / address.

Methods

sign()

Parameters

Parameter	Type
operation	Operation

Returns

Promise<SignedOperation>
