The Bridge

Each review method is good at something the others are not, and each one works better on a surface the previous stage has already cleaned. Tools find the obvious before humans spend time on it. Humans find what tools cannot. Fixes get reviewed rather than trusted. Proofs cover what review cannot guarantee. A bounty catches what everything before it missed.

Run out of order, each stage does less work than it could.

Valkyri Security review the agreed scope across infrastructure, web2 and web3 components. This establishes the first structured pass over the whole product surface, not just the contracts.

Guards using AI agents and static analysers review the frozen scope, competing for 10% of the prize pool. This surfaces the straightforward and semi-obvious issues before the human contest, so researchers are not paid to rediscover them.

Researchers review the scope with their own methods and attack paths, competing for the remaining 90%. Two Lead Guards anchor coverage; two Lead Judges assess the submissions.

Lead Guards who finish in the top-10 join the review, along with any guards who outrank them and finish inside the top-10. The full-stack partner returns to check that the fixes introduce no new vulnerabilities. The people who found the issues are the people who check the fixes.

These two run at the same time. Dowsers specify and prove the critical properties of the selected contracts, while a pre-launch bug bounty gives researchers a clear channel to disclose anything still standing before your contracts hold real money.

The Bridge is the right choice when your launch needs coverage across applications, infrastructure and contracts; when your protocol has critical properties that benefit from formal verification; and when you want a defined workflow through to pre-launch readiness rather than a sequence of separately negotiated engagements.

The DualGuard contest and bug bounty are priced as usual. Work delivered by partners is priced by those partners.
