HackenProof is Hacken's Web3 bug bounty and crowdsourced audit platform. It combines ongoing vulnerability reward programs with time-boxed audit programs for smart contracts, exchanges, wallets, bridges, and L1/L2 ecosystems.
This page shows only Web3-relevant programs aggregated from HackenProof. For audit contests and bounties on other platforms, see the full Web3 audit competition tracker.
Six major platforms host the Web3 audit competitions and smart contract bug bounty programs aggregated above. Click any platform to see only its active contests.

HackenProof runs public bug bounty programs, private bounty programs, and crowdsourced audits. In Web3, its listings include smart contracts, bridges, exchanges, wallets, and L1/L2 ecosystems.
Open the protocol program page on hackenproof.com, review the scope, severity, reputation, and proof-of-concept requirements, then submit through the HackenProof dashboard.
The leading Web3 bug bounty platforms are Immunefi (largest, $15M max payouts on DeFi protocols), Cantina (Spearbit's bounty program plus audit competitions), HackenProof (managed Web3 bounties and crowdsourced audits), Sherlock (audit contests with insurance-backed bounties), and Code4rena (best known for time-boxed audit competitions). Codehawks rounds out the field with Cyfrin-run contests focused on emerging protocols and beginner-friendly First Flights.
Cantina runs the largest audit competitions ($2M+ prize pools for protocols like EigenLayer and Uniswap v4). Immunefi pays the highest per-bug bounty (up to $15M for critical findings). Code4rena and Sherlock typically run $100K-$500K audit contests. Codehawks First Flights are smaller but accessible to newer auditors.
Audit competitions invite security researchers to review a protocol's smart contract code for a fixed prize pool over 1-4 weeks. Rewards are split based on unique valid findings, weighted by severity (critical, high, medium). Code4rena, Sherlock, Codehawks, and Cantina are the main platforms.
Top auditors earn $10,000-$500,000+ per competition. Cantina and Code4rena regularly run $500K-$2M prize pool contests. Bug bounties can pay up to $15M per critical finding on platforms like Immunefi.
Audit contests run for a fixed time window with a fixed prize pool shared among all valid findings. Bug bounties are ongoing programs where each valid submission earns a direct per-vulnerability reward (often $50K-$15M depending on severity). Bug bounties require finding a real vulnerability in production code.
Learn the most common vulnerability classes first: reentrancy, flash loan attacks, oracle manipulation, and access control. The SCH Smart Contract Hacking Course covers all the core attack patterns that audit competitions test, starting from zero experience.
A practical path from learning vulnerability classes to submitting your first contest finding.
Master reentrancy, access control, oracle manipulation, flash loan attacks, and arithmetic overflows. These five classes account for most contest findings.
Read every public report from past Code4rena and Sherlock contests. Try to spot findings yourself before reading the writeup. This is how every top auditor trained.
First Flights are small audit contests designed for newer auditors. Prize pools are under $20K, scope is small, and competition is lighter. They build real submission history.
Pick an active audit contest from the tracker above filtered by Solidity and a $50K-$200K prize range. Spend 20 to 40 hours on the contest, even if you only find one valid medium-severity issue.
Publish your findings, share writeups on Twitter and Mirror, and start accumulating valid submissions across multiple platforms. A documented track record is what opens bug bounty access and full-time auditor roles.
