GPv2Authentication API
Authentication contracts for managing solver authorization in Gnosis Protocol v2. Only trusted solvers can execute trades.
GPv2Authentication Interface
Base interface with a single function:
interface GPv2Authentication {
function isSolver(address) external view returns (bool);
}
GPv2AllowListAuthentication Contract
The primary implementation featuring manager-based access control.
State Variables
address public manager;
mapping(address => bool) private solvers;
Events
event ManagerChanged(address newManager);
event SolverAdded(address solver);
event SolverRemoved(address solver);
Functions
initializeManager
One-time initialization compatible with proxy deployment pattern.
function initializeManager(address manager_) external initializer;
setManager
Reassigns the manager role. Callable by manager or proxy owner.
function setManager(address manager_) external onlyManagerOrOwner;
addSolver
Adds a solver to the authorized allowlist.
function addSolver(address solver) external onlyManager;
removeSolver
Removes a solver from the authorized allowlist.
function removeSolver(address solver) external onlyManager;
isSolver
Checks if an address is an authorized solver.
function isSolver(address solver) external view returns (bool);
Access Control
| Modifier | Description |
|---|
onlyManager | Restricts to current manager address |
onlyManagerOrOwner | Allows manager or proxy admin |
Security Recommendations
- Assign the manager role to a multi-sig wallet or DAO
- Monitor for unauthorized changes via events
- Implement time-locks for critical operations
