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.

What Halo Must Prove

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.

Halo Hunt Focus

Halo is prioritizing chain and settlement, l2, settlement, smart-contracts, and exploit paths that show real user, protocol, or market impact.
