MetaMask SDK

🦊 Best dApp on MetaMask SDK - $2k in prizes

PLEASE NOTE: Using the SDK is not the standard way of interacting with MetaMask that you might be familiar with. Please check our dev guide and examples page to get familiarized with it. Any project that does not use the SDK will not be eligible for prizes.

Develop an outstanding decentralized application (dapp) that uses the MetaMask SDK for secure and seamless integration with our mobile wallet. We are interested in any sort of creative solution you could think of, but if you need some ideas things we particularly like are:

NFT/Gaming - Create a project in the realm of NFTs or web3 gaming, which involves innovative utilization of NFTs, enhances wallet interactions within games, or tackles any of the difficulties in the current gaming landscape. You can also check our “Unity SDK” LINK

DeFi - Create a dapp that enhances the DeFi ecosystem, such as new protocols, enhancing existing derivatives, ecosystem tools, application of NFTs in DeFi, better financial inclusion, DAOs.

Social: Create a project that combines social aspects to decentralization, such as p2p messaging dapps, marketplaces, content creators tools, social proof validation.

*If you are building a React application we encourage you to use our React companion libraries for state management, which can be found in our SDK links section.

Your Dapp should demonstrate innovation, functionality, and a compelling user experience . The winning submissions will highlight the potential of the MetaMask SDK and offer compelling solutions within their respective categories.

Beyond your winnings, you have the opportunity to work alongside Consensys post-hackathon to apply for a MetaMask Grant program. We want to build with you, and with a well-fleshed-out submission, we can help you take your idea to the next level, finish those features you couldn’t get to, or take your project to production.

Requirements:

  • Derp: Repos must contain a text file named “nyc.txt” with the phrase “New New York Big City of Dreams”
  • This attention to detail helps us reward genuine effort and identify quality projects.
  • Code needs to be viewable on GitHub
  • Each submission should have a short video that describes scope and functionality of the dapp
  • We encourage you to have a detailed README that helps the judge know the details about your project, what technology has been utilized as well as which ConsenSys tools like SDK have been used to what extent.
