Scroll is a zero-knowledge rollup built to scale Ethereum. We're committed to Ethereum's ethos, and like to call ourselves the community-first zkEVM.If you’re experienced in building on Ethereum, your code, dependencies, and tooling work with Scroll out of the box. This is possible because our network is compatible with EVM bytecode and designed to feel just like developing on Ethereum. With the launch of the Alpha testnet on Goerli, Scroll is inviting the developer community to join early and begin innovating.

Application users access digital assets on any blockchain, with one click. Developers work with a simple API and access an open market of tooling to automate complex tasks.
You can think of it as Stripe for Web3. More about Axelar: http://axelar.network
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:

Polygon is the leading platform for Ethereum scaling and infrastructure development. Its growing suite of products offers developers easy access to all major scaling and infrastructure solutions: L2 solutions (ZK Rollups and Optimistic Rollups), sidechains, hybrid solutions, stand-alone and enterprise chains, data availability solutions, and more. Polygon’s scaling solutions have seen widespread adoption with 18000+ applications hosted, 1B+ total transactions processed, ~100M+ unique user addresses, and $5B+ in assets secured.
ZM builders, we’re challenging you to hack with Polygon solutions to solve real-world problems.
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.
========================================
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
========================================
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.

UMA is an optimistic oracle that can verify any natural language statement as true on the blockchain, so contracts asking for that data can be settled.
Across, is a cross-chain bridge that supports cheap, secure, and near-instantaneous transfers between L2s and to L1. Across transfers are secured by UMA’s optimistic oracle.
Builders can use UMA as a decentralized truth machine that is flexible enough to handle ambiguity and real-world data with human-powered dispute resolution. UMA secures and empowers a diverse set of Web3 applications, including cross-chain bridges, insurance protocols, prediction markets and customizable DAO tooling products.
Prizes will be awarded to the best projects built on top of UMA's optimistic oracle, or the Across bridge.

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.

Connext is a modular interoperability protocol that lets you build secure crosschain dApps (xApps). With Connext's recent network upgrade, it is now the most trust-minimized interoperability protocol available today for building powerful crosschain functionality with a developer-friendly interface.
What Can You Build?
Using the new primitive, xcall, developers can send assets and any arbitrary data across chains. This means you can build with crosschain interoperability out of the box, allowing your smart contracts to directly interact with other protocols across chains! You’ll find there is a whole realm of new possibilities using features enabled by the protocol, like JS-style callbacks.
xcall allows for a new class of crosschain use cases, such as:
🔗 Crosschain DAO governance
💧 Crosschain liquidity management
💎 Crosschain NFTs
🔮 And many more that have yet to be discovered
