ZM builders, we’re challenging you to hack with Polygon solutions to solve real-world problems.

🔀 $5,000 Best use of zkEVM

The Polygon zkEVM launched earlier this year, it's grown to hold a TVL of $50 million and continues to attract major protocols. For this challenge, we want to see your most innovative use of the Polygon zkEVM, this is an open challenge that will see the most innovative and deserving protocols, with killer UX carry the day!

Check out these resources to get you started.

• Documentation
• Full Stack dApp demo

❌ $5,000 LxLy Bridge zkEVM Extension

gm anon, or should we say ZM. At the heart of Polygon’s new 2.0 architecture lies the LxLy bridge. The Polygon zkEVM LxLy Bridge facilitates cross-chain communication across Polygon chains. We’re challenging you to create and extend the LxLy sample implementations and add support for different types of cross-chain messaging and assets transfer of custom ERC-20s and any other EIP/ERC you see fit such as ERC1155 etc. Check out the existing code samples and open a PR with your own contribution that facilities cross-chain communication.

Cross-Chain ideas from the Polygon zkEVM team 

• Claim UI: Build a Dapp to allow users to connect and see all valid messages they have that are claimable on a given LxLy chain (Polygon zkEVM etc) and claim them!
• Implement an OpenZeppelin Governor that allows token holders to vote on Polygon zkEVM with proposals that are still on Ethereum or Polygon PoS Create a snapshot strategy that accounts for token balance on Ethereum, Polygon PoS, & Polygon zkEVM
• Build a zkEVM NFT project with mint logic that depends on owning an asset on Ethereum or Polygon PoS
• Permissionless Prover: A smart contract that allows Polygon Labs to put up a reward for anyone who fills in as permissionless prover for when our infra goes down essentially a contract that has a function that checks whether a given verifyBatches() call was successfully called by anyone other than our trusted address, and if so, pays out some fixed reward it holds (MATIC tokens)
• Or even extend these repos to cover LxLy Bridging https://github.com/ZeframLou/universal-bridge or https://github.com/aave/governance-crosschain-bridges/tree/master/contracts/bridges

🆔 $5000 Best use of Polygon ID's Verifiable Credentials to preserve user privacy

Self-Sovereign Identity is the future. Use Polygon ID to represent identity-based information as verifiable credentials in your dapp so your users can prove access rights to dapp features without giving up their private data. Polygon ID is also excited to announce a brand new partnership with Dock.io that will allow you to securely extend the privacy of your Lens profile using Verifiable Credentials. Using Dock's REST API credentials can be issued a few API calls. Along with issuing credentials application developers can use the API to manage issuer profiles and create and import data schemas. Dock's tooling also supports non-developers through it's no-code solution Dock Certs which provides the same functionality via a web interface.

This demo shows you how to set up your Dock.io account and begin to issue VCs. Your task is to now leverage VCs to provide additional layers of privacy and security to your Lens Dapp.

Polygon ID resources:

• Polygon ID Dev Docs and tutorials
• How to run an Issuer to issue VCs: Video by Tony
• Fullstack VC-gated dapp template with everything you need for your KYCAgeCredential gated dapp by Steph
• This demo shows you how to set up your Dock.io account and begin to issue VCs. Your task is to now leverage VCs to provide additional layers of privacy and security to your Lens Dapp.

Ideas from the Polygon ID team:

• Anonymous voting - On-chain voting exposes the choices made by different public addresses. Create a hack that proves DAO membership with a VC while making sure members don’t double vote.
• Social proof of influence or activity - Create a proof of influence issuer that issues VCs based on numbers of followers or number of posts across social platforms
• Bot protection - Create a decentralized verification system providing individual VCs of liveliness & uniqueness that could be combined to prevent sybil attacks.

Lens Ideas:

• KYC: Imagine if you can securely add KYC to your Lens dapp and be able to rely on the authenticity of that data
• “Lenster badges” from Polygon ID credentials: Import a Polygon ID credential and create a Lenster badge from it (Proof of Hacker, Proof of Human, Polygon Activist,). You could combine these with any of the credentials from WIW or any of the free credential issuers that use Polygon ID.

Lenster badge

You don't need to implement a full product; it's better to tackle one feature at a time.

🚫 Anti-plagiarism service Prize: $3,000

Finding a unique hackathon idea can be challenging. It's even more disheartening to discover post-event that your concept wasn't original. How about developing a service to cross-reference ideas with those from past hackathons?

Possible features

• Search for related projects
• Upload repository (documentation)
• Claim SBT token with proof of ownership (contribution)
• COmpare code similarities (within documentation)
• Integrate projects from established hackathon platforms.

You don’t need to implement a full product - you can go feature by feature.

🔐 Anti-sybil service Prize: $3,000

In the Web3 industry, most projects can't distinguish between personal, corporate, or bot wallets. This situation creates potential for Sybil attacks on the protocol (like airdrop hunting, facets abusing, claiming other free resources by bots, etc.). A few solutions for this already exist (like identity protocols, Web3-captures, SBT tokens, etc.) but the cost, speed and cross-chain solutions (like Hashi or other bridges) of Gnosis Chain allow for the creation of next-level anti-sybil services. Are you up to the task?

Possible ideas

• Identity Protocol Aggregator: make a one-point service for interaction with a variety of identity protocols on other chains
• Wallet Activity Behavior Analysis: A tool to discern whether the wallet activities are orchestrated by humans or bots.

Remember: you don’t need to implement a full product - it's better to go feature by feature.

✅ Survey service Prize: $3,000

Platform for creating surveys and engaging with community members

Possible features

• Create personal profile (SBT with profile, statistics, etc)
• Create cohort-specific surveys featuring prize draws (and create POAPs for all participants)
• Statistic cleaner for collected data

Remember: you don’t need to implement a full product - it's better to go feature by feature.

🚚 Tool to migrate projects to Gnosis chain from another EVM Prize amount: $3,000

There are a lot of services and dApps that are widely used on other EVM chains. Consider creating a service that helps to migrate projects from one EVM chain to another.

Possible workflow

• Input contract address to download a code
• Service check reference smart contracts, advise addresses of analogy contracts on Gnosis chain
• Deploy fixed code to Gnosis Chain (possible gasless deploy)
• Advise improvements of UI

You don’t need to implement a full product, it is best to go feature by feature.

🎮🌠 Games Infrastructure Prize: $3,000

The GameFi is dead; long live the GameFi. Let’s reinvent Web3 games by providing more than just play-to-earn mechanics. With Gnosis Chain, it is possible to implement true on-chain games (with 1 xDai you can mint 2000 NFTs and the average block time is just 5 sec).

Possible ideas

• Matching engine for players in p2p game
• Betting for game (look at Azuro and connect it to game)
• Turn-based strategy or other games that could store state on-chain

We don’t expect that you will create an AAA game during the hackathon and everything will work perfectly. Take an already existing open-source game and turn it into an on-chain game.

Don’t worry if you face some troubles that will not allow you to make a stable project. In this case, prepare documentation and tests that help to reproduce your problems.

💡 Innovate on Gnosis Chain **Project: $2,000 (shared)

Axiom is the first ZK coprocessor scaling data-rich applications on Ethereum. ​Axiom gives smart contracts trustless access to all on-chain historic data and verified compute over that data. With Axiom, developers can build on-chain applications that use data like historic contract variables, transactions, and receipts that smart contracts cannot access through the EVM. All results returned by Axiom are verified by a ZK proof, meaning that they have security cryptographically equivalent to Ethereum itself.The Axiom SDK and frontend give teams with as few as a single developer the ability to build powerful apps making use of the latest advances in ZK. Developers can write and deploy their own ZK circuit, reference historic on-chain data, and integrate into their application, all through an easy-to-use Typescript interface.

• 🏆 Best overall use of Axiom $5,000.00
• 💡 Most creative use of Axiom $1,250.00

Hyperlane is the first interoperability layer that enables you to permissionlessly connect any blockchain, out-of-the-box. With Hyperlane you can connect your app to any chain, and easily have interchain function calls or asset transfers. Hyperlane has a one of a kind modular security stack, that allows you to configure your security model, and customize the security protocol you use to fit the action of your users.

Browse hackathon ideas here: Hackathon Success Guide

🥇Top prize - $4,000 - Best use of Permissionless Interoperability

To qualify to win this prize you simply need to deploy Hyperlane on a new blockchain or Rollup. Once deployed, how you utilize your new-found interoperability capabilities will dictate how likely you are to win the grand prize! Could you be the first one to bring Hyperlane to Scroll? Or Fuel? What about other chains participating in the hack? You could even deploy to your own chain! The most compelling submissions will be those that have built an application through their deployment. Additionally an extremely compelling Interchain Application that does not leverage a unique Hyperlane deployment can be eligible as well. See below for more ideas about Interchain applications.

🎼 $2,000 - Best Interchain Application

An interchain application is an app that communicates between chains, it either transfers assets or has interchain function calls. The winner of this prize would be the most compelling application that leverages Hyperlane, and benefits from its presence on multiple chains!

💸 $2,000 - Best use of Hyperlane Warp Routes

Warp Routes are Hyperlane’s unique take on token bridging. They are unique and instanced expression of bridging as opposed to the traditional omnibus token bridge design. Each Warp Route can have its own security model, using Hyperlane’s Interchain Security Modules. Perhaps most importantly, Warp Routes are completely permissionless! No one can stop you from bringing whichever asset you’d like to any chain you’d like.

So how can you win this prize? While the only strict requirement is that you use Warp Routes in your submission, the more creative you get with it the better!

🌐 $2,000 - Write new Interchain Security Modules (ISMs)

Hyperlane’s Modular Security Stack is premised on a variety of available Interchain Security Modules that developers can use to secure how applications can communicate between chains. While a few ISM’s are already available, and more are in the works, the hackathon is a great opportunity to build new ones.

Dear Builders,

Mask Network brings privacy and benefits from Web3 to social media like Facebook & Twitter - with an open-sourced browser extension. Next.ID was initiated by the core team responsible for the development of Mask Network last year.

Next.ID is an open-source protocol designed for developers to create and manage identities. The Next.ID protocol acts as a secure conduit connecting various web2 and web3 identifiers, such as wallets, Twitter profiles, ENS names, Lens profiles, and more.

When a person's different identifiers are linked together, they form an identity graph, creating powerful, portable, and self-sovereign digital identities. We refer to these identities, digital representations of self, as Avatars at Next ID.

You can check out what Avatar is at here.

You can find more information on our official site: https://Next.ID

Our GitHub page: https://github.com/NextDotID

We are here to help you overcome any challenges:

Join our Community Telegram Group for quick assistance: https://t.me/NextDotIDofficial

For any questions, feel free to send an email to developer@next.id

On this occasion, we have prepared a bounty of 10,000 USD for you to explore and build upon. We look forward to seeing your innovative contributions!

#1 Paving the Way for an Autonomous World: Creating a Secure and User-Friendly Identity Solution for On-Chain Gaming (4k USD in total)

Prize Pool

1st prize (max 1): $3k USD

2nd prize (max 1): $1k USD

Description

What is Fully On-Chain Gaming

Fully on-chain games like Dark Forest and Loot have all interactions, behaviors, and states processed via the blockchain, serving as the game's server. These games also use smart contracts for all player actions and even allow for decentralized narratives and governance through DAOs.

General Challenges We Are Facing

• Technical Limits: Low throughput and high latency hinder real-time interactions.
• Smart Contract Complexity: It is difficult to encode all game rules in smart contracts.
• Hidden Info: Challenges in implementing games with hidden or incomplete information.

Specific Questions We Noticed as a DID open source protocol

Burner wallets in on-chain games like Dark Forest enhance user experience by automating transactions. However, they lack secure, intuitive key management, making them temporary solutions for storing in-game assets. This complexity limits participation to technically savvy users and hinders cross-game interoperability and reputation building in the autonomous world.

Our Thoughts to the Solution Which You May Need

In general, we propose to design a Game Account system similar to how Steam ID functions for all games within the Web2 world's platform.

A possible approach to how we design the Game Account System:

• it can work as below, or you can design your own structure:
• Entry Point → Game Account → Game
• In Game Account section, it contains 3 parts:
• AA wallet to perform as the login window
• Proxy Logic to handle business
• Access Control module to check if AA Wallet is properly linked with the Identity Graph
• A Session Key handles the Entry Point
• Frontend SDK for creating these Session Keys, binding with Avatar（the gate where the user becomes one of the dots in the Identity Graph）
• Solidity library for on-chain game logic integration

We invite Dev with us to co-build this comprehensive identity solution for on-chain gaming, lowering entry barriers for end-users. The toolkit may include:

• Web/Mobile SDKs
• Optional Backend Service
• Smart Contract Library
• Sample Game
• Docs

The solution consists of two parts: off-chain and on-chain.

• Off-chain

1. (Existing users) Use their existing wallet as their Avatar (sharing the same private key)
2. (New users) Generate their own MPC-controlled avatar with their email
3. For each session of each game, generate a burner per-device session key (that may or may not have an expiry time) and use Next.ID to bind with the avatar
4. For each new session, repeat the same
5. Each session/device key never leaves the device and could expire to protect security
6. In-game assets and game status are synced through and built upon the avatar, which can be considered as a universal reputation

• On-chain

1. Generate a smart contract wallet along with identity graph(https://docs.next.id/?utm_source=nextid#what-is-an-identity-graph)
2. Tokens can be airdropped to these wallets to pay for game plays from game creators
3. identity graph is used to maintain on-chain social capital based on identity bindings, which can be used as factors for token airdrops or small credit loan
4. A solidity identity library is needed to integrate into game logics to realize game asset and game status synchronization.

BOS (Blockchain Operating System) is the easiest way to build and deploy your frontend on-chain by creating a JSX Component. All of the frontend source code on BOS is stored on-chain on Near, making your frontend fully decentralized and open-source. While the frontend is on Near, it can interact with smart contracts on any EVM chain in the backend. Components are also composable, meaning you can reuse and remix different components together and embed them into your dapp.

You are encouraged to incorporate this challenge into your submission for ETHGlobal NYC by creating a frontend component for your final project with BOS and deploying it on near.org. You can also build a custom BOS frontend for any existing EVM dapp as your final submission (see examples of BOS components for 1inch, Lido, or Uniswap, for inspiration).

Selection Criteria

Base Criteria (all submissions):

• You must submit a link to your dapp or project with a live, working BOS Component
• The component should prompt the user to connect their Ethereum Wallet of choice
• The component should display on-chain data (e.g. account balance / tokens), and allow the user to make a transaction through it
• The component should NOT be a simple fork of an existing BOS component with minimal changes

An outstanding submission is: A live working frontend component deployed to the Near mainnet that interacts with a popular protocol on the Ethereum mainnet, L2s, or other chain supported by Blocknative infra. Everything in production. A user connecting to the component with a wallet should be able to make a transaction on mainnet in addition to viewing data from a smart contract. The frontend should support the majority of the features in the protocol.

TLDR:

• Comprehensiveness of functionality
• Production-grade user experience

Flashbots is a research and development organization formed to mitigate the negative externalities posed by Maximal Extractable Value (MEV) to stateful blockchains. Our primary focus is to enable a permissionless, transparent, and sustainable ecosystem for MEV, via a three-pronged approach:

• Illuminate: bringing transparency to MEV activity.
• Democratize: democratizing access to MEV revenue.
• Distribute: enabling sustainable distribution of MEV revenue.

We have brought transparency through open MEV activity analytics and dashboard and public and open research, with the community, for the ecosystem. We have democratized access to MEV revenue with MEV-Boost that gives all validators access to MEV revenue on equal footing, with the support of a vibrant ecosystem of builders and searchers.

We have started distributing MEV revenue using the MEV-share protocol. This protocol returns 90% of captured MEV to users, wallets, and dapps, who can enjoy its benefits simply by sending transactions with programmable privacy to Flashbots Protect. MEV-share also poses a new challenge for searchers, as they must now learn how to compete for and execute against users' private transactions.

Where to find us: Website | Github | Forum | Discord | YouTube

🚀 Open/Innovation Track - $1500 - Unveiling the MEV Potential

To seize this prize, construct a project that showcases SUAVE, MEV, or programmable privacy concepts, including but not limited to DeFi, Gaming, or any auction market in real life use cases.

🌍 Ecosystem Track - $2000 - Broaden the MEV Landscape

🎲 MEV GAME

Develop a game which leaks MEV that searchers can compete on to stress test order flow solutions like mev-share or new chains testing their MEV-proofness (see Base leaky mempool). Ideal projects might feature a weakly random encrypted password that challenges searchers to brute force for MEV rewards. Ideally this could easily be deployed on any chain.

💻 MEV-aware Uniswap frontend / Flashbots Protect UX

Produce an MEV-aware Uniswap frontend fork, informing users about potential MEV from their trade and directing them towards MEV-share and showing an estimated refund amount.

🪔 Backrun My Oracle (MEV-share for Oracle Usecase)

Craft a system where oracle updates can be auctioned via MEV-share or similar services, promoting transparency and dynamic updates.

All projects in the Ecosystem Track should integrate core MEV principles and tools.

📈 Data Analysis Track - $1500 - Illuminate the MEV Supply chain

🤕 rekt.wtf (MEV Lookup Tool for Uniswap Users)

Construct a info site, with lookup function for anyone to query their past Uniswap DEX Trades' MEV related metrics, e.g.:

• the MEV extracted from MEV Bot;
• the slippage caused by Trade Collision
• the ideal price on top-of-block, so to compare the execution result.

📊 Swap Execution Dashboard

Design a simulation bot, to query across major DEX/DEX-aggregators' execution quality based on same trade request, so to help the community understand if really:

• aggregators (e.g. 0x API, 1inch) are providing better quotes than DEX? (e.g. Uniswap)
• meta-aggregators (e.g. DeFiLlama, CowSwap) are providing better quotes than DEX/aggregators?
• is solver system (1inch Fusion, Coswap) providing better quotes than traditional aggregators?

and/or, combine with empirical analysis on historical data:

• How vulnerable are each platforms' orders towards MEV?
• How are price execution (settled token amount onchain) compared between each platform?

🌡️ Mempool Hygrometer

Is the public mempool really drying up, with orderflow moving to private mempool (i.e. each builder's)? With the copy of public mempool dataset, build a website to showcase how the private orderflow landscape look like: by checking the onchain transactions included in each builder's block, and cross checking the public mempool history, we shall be able to identify how much of the flow are public vs private, per each builder. How did that evolve over time? How MEV valuable are they? Add metrics and visualizations to inform the mempool evolution after the adoption of MEV-boost, order flow auctions.

Projects in the Data Analysis Track should focus on illuminating the dark corners of the MEV supply chain. Additionally there are already tools which attempt to do some of these so a compelling project will do something that hasn't been done yet.

For Ecosystem Track: Coming soon!
