- Web3 protocol teams and bug-bounty researchers
- Worth noticing
- The site says a finding needs a passing Foundry test on a block-pinned fork, with zero transactions sent to the live network.
Field notes
The described intake accepts a bounty-program URL or a contract list, then sorts addresses into four scope classes, including own assets and test fixtures. The page also says its nine-stage pipeline checks cheaper stages first and treats out-of-scope addresses as a hard stop with zero downstream calls. It names a range of tools and bounty platforms, including Foundry, Slither, Immunefi, and Sherlock.
