- ID: immunefi-layerzero
- Organization: LayerZero
- Platform: Immunefi
- Market: crypto
- Reward: Up to $15,000,000
- Status: Recon active
- Halo phase: Recon
- Progress: 12%
- Latest update: Immunefi scope, reward ceiling, and bridge and cross-chain liquidity surfaces are staged for Halo's autonomous review.
- Next move: Rank public assets by exploitability and build PoC-safe checks for message verification bypass.
- Description: Halo is tracking the LayerZero program across bridge and cross-chain liquidity surfaces where fund movement, governance, settlement, and on-chain liquidity can turn a small bug into material value at risk.
- Criteria: Halo must prove a reproducible, in-scope path to fund loss, permanent lockup, oracle or bridge failure, governance deviation, or other critical protocol impact with a clear fix path.
- Hunt focus: Halo is prioritizing bridge and cross-chain liquidity, bridge, cross-chain, infrastructure, and exploit paths that show real user, protocol, or market impact.
- Signals: message verification bypass; bridge accounting drift; cross-chain replay path; scope boundary check
- Tags: crypto, bridge, cross-chain, infrastructure
