  • Signing: Ed25519 with deterministic JSON serialization; public key is stored alongside each credential.
  • Validation: Global validation pipe is enabled (whitelist + forbid non-whitelisted + transform).
  • Default port: 3000 (override with PORT env var). CORS is enabled.
  • Key storage: key pair is encrypted at rest with KEYPAIR_PASSPHRASE (required).
