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.
ETHDenver Chainlink Bounty Winners
The winners below are highlighted in alphabetical order.
Crypto Plants rewards philanthropic cryptocurrency donors with unique NFTs to encourage social sharing and social good. Developers Shardul and Daksha Aeer built a dApp that allows users to select a charity, pay in ETH, then receive an NFT featuring a potted plant. The project uses Chainlink oracles to make an API call and fetch the NFT metadata including the plant image, description, types, and other elements on-chain. This is a great example of using Chainlink oracles to power provably rare and dynamic NFTs that react to external data inputs, a key functionality in the rapidly growing NFT landscape.
The goal of Crypto Plants is to encourage environmentally and socially conscious giving, using the benefits of digital scarcity to reward donors with verifiably unique digital status symbols.
