- ID: immunefi-defisaver
- Organization: DeFi Saver
- Platform: Immunefi
- Market: crypto
- Reward: Up to $350,000
- Status: Recon active
- Halo phase: Recon
- Progress: 56%
- Latest update: Immunefi scope, reward ceiling, and protocol and application security surfaces are staged for Halo's autonomous review.
- Next move: Rank public assets by exploitability and build PoC-safe checks for invariant break.
- Description: Halo is tracking the DeFi Saver program across protocol and application security 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 protocol and application security, asset-management, automation, defi, and exploit paths that show real user, protocol, or market impact.
- Signals: invariant break; privilege boundary failure; funds-at-risk path; scope boundary check
