As a first-time sponsor at ETHGlobal’s ETHOnline, which is the world’s largest DeFi hackathon, we were blown away by the innovation and creativity of all the DeFi projects! Congrats to a record participation by 1150 hackers from over 77 countries and 220 projects submitted. We had several fantastic submissions using the Covalent unified API to bring transparency and visibility to assets across all blockchain networks. The Covalent API is ideal for hackathons because it is simply the fastest way for teams to access granular and historical on-chain data without code, unlocking One Billion possibilities.
All the teams using the Covalent API built projects which are good enough to be their own startup, and we look forward to seeing some of them take the next step! Check out the winning projects below (in no particular order) which will split the $3000 USD Covalent prize pool!

Quote from Mark Carey, Degen Dogs
“ For Degen Dogs, I used the Covalent API to fetch the 'new bid' events from the Auction House contract, which gets emitted each time a new bid is placed during an Auction. The Covalent API makes it really easy to fetch only the data that I really need, along with timestamps for each bid placed.

Quote from Taylor Waits, Fae WorkSpace
“ Covalent API is the most organized, versatile, and seemingly limitless API that I have personally used in the crypto space.
