# NoSelfProxy (/docs/errors/chain/NoSelfProxy)

An account attempted to register itself as its own proxy, which is not allowed. Check the `delegate` argument to `add_proxy` and ensure it differs from the calling (delegator) account.

Declared by the `Proxy` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).
