/**

* @title IFunctionValidator
|
|
* @notice Service interface for validating function calls in the context of ERC-4337 operations
|
|
* @dev This interface defines a standard for validators that determine whether a paymaster
|
|
* should sponsor a specific operation. Validators implement custom logic to check if
|
|
* a Light Account owner is authorized to perform a specific function call.
|
|
*
|
|
* Key features:
|
|
* - Stateless validation of operations
|
|
* - Function-specific authorization logic
|
|
* - Integration with paymasters for gas sponsorship decisions
|
|
* - Support for complex validation rules
|
|
*
|
|
* Usage:
|
|
* - Paymasters (like PaymasterV1) call validators to check operations
|
|
* - Each target contract/function pair can have its own validator
|
|
* - Validators can check voting power, roles, balances, or any other criteria
|
|
*
|
|
* Example implementations:
|
|
* - StrategyV1ValidatorV1: Validates voting operations in governance strategies
|
|
* - Custom validators for specific business logic
|
|
*
|
|
* Security:
|
|
* - Validators should be carefully audited as they control gas sponsorship
|
|
* - Must handle edge cases and prevent exploitation
|
|
* - Should validate all relevant parameters
