SmartSession is an advanced module for ERC-7579 compatible smart accounts, enabling granular control over session keys. It allows users to create and manage temporary, limited-permission access to their accounts through configurable policies.
SmartSession is a collaborative effort between Rhinestone and Biconomy to create a powerful and flexible session key management system for ERC-7579 accounts. It offers a comprehensive solution for secure, temporary account access in the evolving landscape of account abstraction.
- Granular control over session keys
- Support for various policy types:
- User operation validation
- Action-specific policies
- ERC-1271 signature validation
- "Enable flow" for creating session keys within the first user operation
- Optimized for ERC-7715 flow for requesting permissions
- Nested EIP-712 approach for EIP-1271 signature validation (aka ERC-7739)
- Native Support for ERC-7579 batched executions
- Integration with external policy contracts for flexible permission management

To use SmartSession in your ERC-7579 compatible smart account:
- Deploy the SmartSession contract.
- Install the SmartSession module on your smart contract wallet.
- Create and configure sessions with desired policies and permissions.
- Use the session keys to perform limited operations on the smart contract wallet.
