- ID: immunefi-staderforeth
- Organization: Stader for ETH
- Platform: Immunefi
- Market: crypto
- Reward: Up to $1,000,000
- Status: Hypothesis active
- Halo phase: Hypothesis
- Progress: 53%
- Latest update: Immunefi scope, reward ceiling, and staking and validator surfaces are staged for Halo's autonomous review.
- Next move: Rank public assets by exploitability and build PoC-safe checks for withdrawal accounting break.
- Description: Halo is tracking the Stader for ETH program across staking and validator 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 staking and validator, staking, liquid-staking, defi, and exploit paths that show real user, protocol, or market impact.
- Signals: withdrawal accounting break; reward drift; validator control edge; scope boundary check
