Class: Ed25519ProtocolSigner

Defined in: packages/overcast-core/src/protocol-signer.ts:47

The default OvercastProtocolSigner: ed25519 over @noble/ed25519, a pure-JS implementation that runs identically in Node, browsers and other runtimes (no dependency on Node's built-in crypto). Built from a 32-byte seed (the leading half of an ed25519 secret key); createProtocolSigner derives that seed from the config's privateKey.

Use Ed25519ProtocolSigner.create rather than new — deriving the public key from the seed is async.
