Review plans that change when the repo does

From first deploy to the next fork: a contest desk, a retained desk, or both. Scope stays tied to the code you are about to ship.

Audit Contest

A contest puts several independent reviewers on the same repo at once. Findings are graded, then you get one paper trail.

Teams that ran a contest

" We ran more than one desk. Hanul Circuit is the one we kept for the protocol and the assets. "

Yubo Ruan, Founder of ParaX

" The desk matched reviewers who read the model, not only the Solidity. That is the review we wanted. "

Demian, Product Lead of Aark Digital

" Security and a public paper trail are what make the rest of the launch worth building. The Hanul Circuit desk delivered both. "

Eric, Head of Product of Mantle Network

" The contest hit a short deadline, the findings held up, and we published the paper. "

Charles, CTO of KaratDAO

" A contest desk on the repo before the layer opens to users. That is the bar. "

Anton Astafiev, Matter Labs' Head of Security

" More useful findings than the last centralized desk, on a smaller invoice. "

Project Aki

" Short deadline, findings that held up, paper we could publish. "

Guoda, team TENGOKU

" The contest caught a re-entrancy the previous desk missed. We patched on-chain before the stake moved. "

Charles, Founder of Shield Protocol

" Reviewers are paid for the severe findings. That alignment is why we stayed with the desk. "

Jack Xu, CTO of EthSign
