## Access control

| Role             | Tokens                                    | Factories    |
| ---------------- | ----------------------------------------- | ------------ |
| Owner            | Full control (mint, burn, pause, upgrade) | Full control |
| Bridge           | mint/burn only (L2, bridged mode)         | —            |
| SuperchainBridge | crosschainMint/Burn only                  | —            |

## Mechanisms

1. **Ownable2StepUpgradeable** — two-step ownership transfer
2. **ReentrancyGuard** — on all factory functions
3. **Pausable** — emergency stop on transfers
4. **UUPS onlyOwner** — only owner can upgrade
5. **EIP-7201 storage** — no collisions on upgrade
