Chain B validators first sign a new proof accepting the liability, then Chain A validators sign a proof releasing their liability once they receive confirmation. This ensures the user always holds exactly one valid, L1-verifiable proof. 4. **L1 State Monitoring:** All validators continuously monitor the Shared Nitro Vault on Ethereum for finalization events, particularly users who exit via the escape hatch. When a user withdraws directly from L1, validators detect this event and update their local chain state to reflect the reduction in total bridged assets, ensuring the system remains economically consistent.
