About New York Event:The city that never sleeps when it comes to pushing the boundaries. Home to the largest stock exchange and traditional financial institutions, New York is rich in history and significance. But New York is also the dynamic hub of change to be reckoned with. A nurturing ground for disrupting the way we think, shaping how we engage with this new world - and reimagining a decentralized, distributed future. Join us from September 22-24 in one of the most iconic cities in the world. Hack with some of the most skilled web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem. We hope the stunning views of Pier Sixty will inspire you to try your best as you get a chance to win over $450,000 USD in prizes!1. MetaMask Snaps // Build a Transaction Insights V2 snap – $1k in prizesThis second iteration of the Transaction Insights API, defined in SIP-11, brings about the notion of severity. It allows your snap to flag an insight as critical, prompting the user for additional confirmation. We want to see you build any innovative transaction insights snap using this new feature. Requirements:Code needs to be viewable on GitHubInclude a README that describes how to install and use the snapCode should be runnable by our judgesEach submission should have a short video that describes scope and functionality of the snapCriteria:UtilityTechnical sophisticationInnovation and uniqueness of features within the chosen categoryUse the MetaMask SDK in your code2. MetaMask Snaps // Build a domain resolution snap – $1k in prizesIn an effort to increasingly modularize the wallet and allow for resolution beyond ENS, we decided to open up domain and address resolution to snaps! We want to see you build an innovative domain resolution snap for the chain(s) of your choice. Requirements:Code needs to be viewable on GitHubInclude a README that describes how to install and use the snapCode should be runnable by our judgesEach submission should have a short video that describes scope and functionality of the snapCriteriaUtilityTechnical sophisticationInnovation and uniqueness of features within the chosen category3. MetaMask SDK // Best dApp on MetaMask SDKPLEASE 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 GitHubEach submission should have a short video that describes scope and functionality of the dappWe 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.Criteria:UtilityTechnical sophisticationInnovation and uniqueness of features within the chosen category.Bonus points for number of Consensys products used (nfura, and Linea)4. Deploy a contract on Linea - $2k in prizes (up to 2 winners)Deploying on Linea is exactly the same as deploying on Ethereum! All you have to do to be eligible is deploy a smart contract. Consider forking our boilerplate code to see what a robust, winning project would look like: https://github.com/Consensys/Form-XChange Linea is an EVM equivalent zk-rollup that offers faster finality and low gas fees to help you scale your dapps.

Help build a public attestation registry on Linea - $2k in prizes (up to two winners)Verax is a shared, public attestation registry that can be used by dapps to store attestations that can be easily accessed and composed together by anyone that's interested. We want you to build a subgraph indexing Verax data and an optional dashboard that visualizes that data. Read more about Verax here: https://verax.gitbook.io/verax/ Continuing Grant: Winners moving forward can work with the Linea team to further build out this public good with support from our grant program. Requirements: Find the full spec here: https://docs.google.com/document/d/1zukSdc4QoMNS6FvZ3-A1o6OmT6qRDEyeavFvdxRIJJ4/edit?usp=sharing Deliverable: Create a Subgraph using The Graph that indexes all event logs from Verax’s four contracts and exposes a number of queries to obtain useful information from the data. Optional bonus points: Create a dashboard that shows visualizations of high level statistics for Verax, from data obtained from the smart contracts using the subgraph. Criteria:Technical sophisticationImaginative and useful queries that are useful to consumers of the dataInformation visualizations (optional bonus points)6. Build a social & identity dapp on Linea - $1k in prizesWe want to see you build the next decentralized chat, identity, or social media dapp on Linea, an EVM equivalent zk-rollup. Build with a social/identity protocol (i.e. XMTP, Push, and Lens) and deploy a smart contract on Linea to be eligible. XMTP and Lens are sponsoring prizes too! Building with them means you can submit to their bounties as well. 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.
