Design and Build with the Covalent API at NFT Hack 2021 to win over $3000 in prizes

Covalent is sponsoring the upcoming ETHGlobal's NFTHack hackathon - bringing together a collective of passionate creatives and developers for a weekend hackathon.

NFTs have seen a recent uptick in the current news cycle - with the $69 million Beeple NFT sale to NBA TopShot record sales to ... a lot more than what we can write about here. NFTs have mainstream appeal and are attractive to a broader audience than the userbase that DeFi targets.

Though the core technological underpinning behind NFTs have been around since the last cycle in 2017, the data underneath NFTs continues to be hard to retrieve. The challenges arise from a combination of non-compliant standards to a portion of the data living off-chain.

The good news is that Covalent has been working diligently over the last few months sorting through the tough data challenges with respect to NFTs. These world-class APIs have been battle tested by some of the biggest NFT projects in the space - ChainGuardians, NFTX, TerraVirtua and many more!

So you're in good company!


Features of the Covalent API

All of us at Covalent are highly anticipating the innovation and creativity that will be on display at NFTHack. With the Covalent API, there is no need to invest developer resources in writing complex sub-graphs or SQL queries. Multi-chain data is immediately available via a unified browser interface where anyone can extract and analyze NFT data in multiple formats.

Some of the NFT-specific features that's available to developers:

  • Index of all ERC 721 and ERC 1155 tokens
  • Index across 4 different blockchains including Polygon, Binance Smart Chain, Avalanche and of course Ethereum mainnet
  • Index of all token ids within a NFT contract
  • Fetching of external metadata
  • Last sale price of tokens across marketplaces like Opensea, Rarible and Zora

You can combine these building blocks to support a wide variety of NFT use-cases.

What we like to see

For the NFTHack hackathon, Covalent is offering a total of 1,500 USDT in prizes to 3 participants or teams who make the best use the Covalent API for their NFT projects. Here are some exciting NFT project ideas we would love to see you #BUIDL:

Our friend Andrew Steinwold had this recent tweet that can serve as a source of inspiration:

Where were they issued?3. Number of holders4. Avg ROIand other relevant info— Andrew Steinwold (@AndrewSteinwold) March 13, 2021 <script async src="" charset="utf-8"></script>
