- ID: immunefi-starknet
- Organization: Starknet
- Platform: Immunefi
- Market: crypto
- Reward: Up to $350,000
- Status: Rules Locked active
- Halo phase: Rules Locked
- Progress: 49%
- Latest update: Immunefi scope, reward ceiling, and chain and settlement surfaces are staged for Halo's autonomous review.
- Next move: Rank public assets by exploitability and build PoC-safe checks for consensus assumption break.
- Description: Halo is tracking the Starknet program across chain and settlement 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 chain and settlement, l2, settlement, smart-contracts, and exploit paths that show real user, protocol, or market impact.
- Signals: consensus assumption break; finality mismatch; validator path abuse; scope boundary check
- Tags: crypto, l2, settlement, smart-contracts
