The Spring 2021 Chainlink Virtual Hackathon is underway! Sign up today to compete for $125k+ in prizes.
We’re happy to announce the Chainlink bounty winners for the 2021 ETHDenver Hackathon. These projects showcased unique smart contract functionalities using Chainlink’s oracle network in a wide variety of ways, including calling off-chain APIs for GitHub repos, municipal property ownership records, and NBA player performance data. Winning projects also used Chainlink VRF for provably fair on-chain randomization of NFT attributes and gamified ticketing systems. This cohort of winners is a testament to the expansive array of use cases that Chainlink enables beyond the network’s already widely-adopted price feeds.
We awarded projects a total of $5,000 in prizes, with $1,000 to four top projects, and $500 to two runner-up projects. Each ETHDenver hackathon project used Chainlink oracles to securely connect Ethereum smart contracts to off-chain data and resources. We hope these hackathon prizes encourage these teams and more across the ecosystem to continue exploring the broad capabilities of Chainlink-powered smart contracts.
Thank you to all the participants, sponsors, and judges at ETHDenver’s 2021 Hackathon for coming together to #BuildwithChainlink and enabling another burst of innovation around universally connected new smart contract applications.
