Proof of Exploit

Proof of Exploit runs smart contract audits for early-stage Solana projects, priced at a flat $5,000 for a full audit. It's built for teams that need a security review before mainnet but can't wait months or pay what large audit firms charge, on the view that fixing a vulnerability before launch costs far less than fixing it after.

Its audits are hybrid: an in-house engine purpose-built for Solana programs, combining the team's own AI systems with a set of security tools, works through the code for coverage, and human researchers review every finding by hand before it reaches the report. In the team's words, "automation never decides." What sets the reports apart is proof: each finding that matters comes with a working exploit, alongside severity, root-cause analysis and step-by-step fix instructions. Reports are delivered within seven days, the patched contract gets a free re-audit, and projects receive an "Audited by Proof of Exploit" badge, clean results included.

Proof of Exploit was co-founded by Regi Fonseca, a security specialist with more than seven years building and securing blockchain systems for banks, defence and enterprises, and Jesse van Eekelen, an auditor and pentester credited with 500+ vulnerabilities across web2 and web3, 13 of them critical. Projects it has audited include Prflght, Chord Finance and BattleVote, where it found a fee-calculation overflow on large deposits. Teams book a scoping call to check whether their contract is ready for audit. Proof of Exploit is part of Superteam Brazil.
