The Proxy Pallet is a versatile module in the Polkadot SDK that facilitates secure delegation of account operations. It allows users to authorize other accounts, called proxies, to perform specific actions on their behalf. This feature enables enhanced account management, operational flexibility, and secure delegation, particularly beneficial in multi-sig setups and automation scenarios.
Key functionalities:
Account Delegation: Enables accounts to delegate specific operations to proxy accounts with configurable levels of permissions and supports use cases such as transaction signing, staking operations, and runtime-specific actions.
Proxy Types and Permissions: Defines distinct proxy types to grant granular permissions, ensuring proxies can only execute authorized actions.
Time-Limited and Announced Proxies: Introduces time-limited proxies that automatically expire after a predefined duration, enhancing security. It also implements delayed announcements for high-risk actions, allowing users to monitor and cancel actions if necessary.
Security and Revocation: Includes mechanisms for account owners to revoke proxy permissions at any time, ensuring full control while it protects against unauthorized actions through runtime checks and adherence to defined proxy types.
