Looking for some inspirations? Check out our [Ideas List](https://glory-bellflower-ba8.notion.site/Airstack-ETH-Global-Hackathons-2023-31417caf62aa45aca04a1cc612c24971)

**Browse ideas and suggestions on what you can build here: [PROJECT IDEAS](https://carpal-dove-f01.notion.site/Hyperlane-ETHWaterloo-ba09d3ae19134ed496ac3f2d8953e5e4?pvs=25)**

🥇**Top prize - 4k - 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.

 🎼 **2k - 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! 

💸 **2k - 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! 

🌐 **2k - 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.

Airstack enables devs to easily integrate web3 on-chain data and related off-chain data into their apps. 

**🔥** New at ETH Waterloo 2023 **🔥** Web3 Identity Resolver APIs: Query across ENS, Lens, Farcaster, POAPs and NFTs with a single Airstack query/response. Build the future of web3 social interoperability with Airstack.

More powerful than previous solutions, Airstack enables complex queries that combine on-chain/off-chain, cross-chain, cross-project, and identity data, and enables developers to not have to host their own infrastructure to integrate and serve relevant ecosystem data to end-users, providing greater relevance and enriching user experiences.

**🤖** The Airstack AI engine **🤖** enables you to query with natural language (e.g. “show me all tokens held by Vitalik.eth, images of his NFTs, and his Lens and Farcaster usernames”) — a great way to get started learning the APIs!

In this workshop we’ll also walk through React and Python SDKs and demo apps. 

Come to our workshop to learn how easy it is to build data-aware applications with Airstack.
