Proxy Authenticator

A Proxy Authenticator is a way to verify / authenticate the signature / intent of a transaction to be executed by the Proxy is indeed from the controlling Entity of said Proxy.

The Entity can choose the authentication method, typically to be Webauthn / Passkeys. However, more authenticators can be added in the future.

Authenticators are shared between all Proxies and their addresses are stored in D-Chain's Abstract Account module.

Interactions with other contracts / modules​

  • Proxy - does a wasm call for the logic
  • Abstract Account Module - stores the authenticator addresses so that Proxy can use them on authentication in before_tx.

Traits​

All authenticators must implement the authenticator_trait defined in dchain-interfaces package.
