ETHOnline 2026 is ETHGlobal's yearly online hackathon. It runs from September 4 to September 16, 2026 and is open to builders anywhere in the world. ETHGlobal lists it as an async hackathon, so teams build on their own schedule inside the event window.
The prizes page lists 11 partner prizes. The Graph and Hedera each offer $15,000, Arc offers $10,000, World and 1inch offer $7,000 each, ENS, Uniswap Foundation, Ledger and Privy offer $5,000 each, and Chainlink and Bazantic offer $3,000 each. Partners split their prizes into tracks. The Graph, for example, offers $5,000 for the best use of its composable data products, paid as $2,500, $1,500 and $1,000 for the first three places.
ETHGlobal's announcement post says projects must be submitted by Sunday, September 13, 2026 at 12:00 pm EDT. The event itself closes on September 16.
