# Ketju research: StarkGate (Starknet Bridge)

- Verdict: rejected
- Type: Other
- Reviewed: 2026-08-17

## Research summary

The research assessment is adverse because of a recent reliability gap that has not yet been resolved, though this is the narrowest rejection in this batch. L2Beat confirms that Starknet is a Stage 1 ZK rollup, the same rating as Base. Its governance is comparably split between a 2-of-6 StarkWare multisig that sends normal actions through an eight-day on-chain timelock and a 9-of-12 Security Council that can upgrade instantly only in emergencies. Base, Arbitrum, and Optimism have the same zero-delay-once-invoked structure reflected in their registry caps. The incident record keeps Starknet at zero: mainnet halted twice in four months, in September 2025 and on 2026-01-05. Neither halt lost user funds, but both stopped block production. At this review, roughly seven clean months have passed since the later halt, short of the twelve-month bar this registry applies elsewhere. This is the bridges batch's closest case for a near-term reopen, not a structural disqualification.

## Observable review triggers

- Twelve consecutive months with no mainnet halt or block-production outage, counted from the 2026-01-05 incident
- Any future major protocol upgrade is accompanied by a public pre-mortem or rollback plan, reducing recurrence risk
- StarkWare Multisig or Security Council composition or threshold changes are publicly disclosed within 48 hours
- Any confirmed exploit of the StarkGate bridge contracts themselves
