List of Bug Bounty Competitions projects in Web3 (2026)

Magnus is Immunefi's unified security operations platform for onchain protocols. It runs Immunefi's bug bounty programs, audit competitions and invite-only researcher programs, with Managed Triage to filter incoming reports, onchain Vaults that hold bounty rewards, and Safe Harbor coordination for whitehat fund rescues during live exploits. It also aggregates third-party security tools, automations and role-specific security agents in one dashboard.

Immunefi Bug Bounty Programs enable security researchers to responsibly disclose onchain vulnerabilities in smart contracts and applications before they can be exploited. The platform facilitates bug triaging and program management for blockchain projects.

Immunefi Audit Competition is a time-bound code reviews from best-in-class security researchers. The system enables competitive security assessments with structured reward pools for vulnerability discovery.

MixBytes Camp is a competitive audit contest platform enabling blockchain projects to source vulnerability reports from a vetted community of independent security researchers. Projects provide a scoped smart contract codebase and a prize fund; a coordinator manages participant onboarding, contest logistics, and finding triage before delivering a unified audit report. Researcher remuneration is calculated based on the severity and validity of submitted findings.

Remedy Bug Bounty Platform operates as a Web3-focused vulnerability discovery system using zero-knowledge proof technology for duplicate protection and expert triage by Hexens security researchers.

Remedy CTF hosts Web3 security capture-the-flag competitions focused on Solidity/EVM, ZK/Crypto, and blockchain-specific challenges with substantial prize pools for security education.

Cantina Competitions is a crowdsourced security review service where multiple security researchers evaluate code to identify vulnerabilities. It offers wide coverage through competitive assessments with controlled communication channels.

Cantina Bounties is a bug bounty program connecting protocols with security researchers to report vulnerabilities. Reduces spam and improves quality control through researcher reputation management.

Bug bounty platform connecting Web3 projects with ethical hackers for crowdsourced vulnerability discovery and security testing. The system facilitates coordinated disclosure programs, manages researcher payouts, and provides triage services for submitted security findings across blockchain protocols and decentralized applications.

RedTeam is a decentralized cybersecurity platform built on Bittensor that gamifies ethical hacking through competitive programming challenges. The system rewards participants with TAO tokens for developing solutions to bypass security mechanisms.
