The open source bounty market is estimated at $50M+ annually across platforms like Algora, Gitcoin, Immunefi, and direct GitHub bounties. Platforms like Tenstorrent offer $500–$10,000 per bounty. WarpSpeed pays $330–$960 per task. The theory is simple: Find bounty issues on GitHub Write the fix Submit a PR Get paid when merged The practice is... different. The Competition Problem When I started, I assumed the bottleneck would be finding bounties. It's not. The bottleneck is speed and quality .
