Blockchain Bridging Support
Resources Required
- 1 Researcher
- 2 Engineer
Risks
- Security of bridge is critical - must handle malicious sequencer scenarios
- Handling finality of user deposits is complex; if not handled correctly, unfinalized deposits could be reverted on the blockchain without the corresponding zone-side mint being reverted
Deliverables
Bridging Protocol
Owner: David Rusu
Feature: FURPS
Implement bridging support in the blockchain and expose it through the Zone SDK, enabling Sovereign Zones to bridge tokens between the blockchain and their zone.
FURPS:
- F33. Channel Balance management
- F34. Sequencer signing on withdrawal
- F35. User deposits from Blockchain to LEZ
Checklist:
- Channel account protocol: permissionless deposits, threshold-signed sequencer withdrawals
- Atomic bridging: user deposit is atomically included on chain with the zone’s inscription tx
- Async bridging: user deposit waits for finality before inclusion on chain
- Deposit events exposed through the Zone SDK
