Build. Submit.
Vote. Fund.
On Solana.
ChainHack is a Solana-native platform for hackathons, bounties, grants, and on-chain builder reputation. Every commit you ship, every vote you receive, every prize you win permanently yours.
Hackathons are stuck in Web2.
We're rebuilding them on-chain.
Reputation is scattered across Discord, Notion, and Google Forms and vanishes when servers shut down.
On-chain identity. Every commit, submission, and prize anchored to your wallet. Portable. Verifiable. Permanent.
Winners wait weeks for prize money. Sponsors juggle spreadsheets, wires, and tax forms across jurisdictions.
Smart-contract escrow releases prizes the moment voting closes. SOL, USDC, any SPL token sub-second finality.
A handful of judges decide outcomes behind closed doors. Community signal is an afterthought.
Quadratic voting. MACI-style judging. Sybil-resistant. Every signal settles transparently on Solana.
One platform.
Every flavor of building.
From weekend hackathons to multi-million-dollar grant rounds, ChainHack handles the entire builder lifecycle.

What builders & organizers say.
ChainHack is the first hackathon platform that actually understands what builders need. On-chain rep means my GitHub work finally compounds across hackathons.
We ran our Q3 grant round on ChainHack. QF settled in 30 seconds, payouts went out automatically, and we cut admin work by 80%. Hard to go back.
Sybil resistance via MACI + Civic is the killer feature. We finally trust the voting signal because we can verify it ourselves. Game changer for grants.
Built in public.
Shipped on-chain.
