ENS (Ethereum Name Service) is a decentralised naming protocol for the new internet.
ENS enables you to have a portable web3 username and profile. Use it to establish an online identity, simplify crypto payments for any blockchain, host decentralised websites, and more. ENS supports all DNS names (.com, .xyz, etc.) in addition to our native .eth TLD.
ENS is simple on the surface, but there are a number of backend infrastructure pieces that could make ENS even easier to use for developers! We'd love to see you get creative, but will get you started with two ideas:
• A backend service that indexes ENS resolver smart contracts for events where people attach an IPFS hash to their name, and automatically pins those files. Build this as an easy-to-self-host Docker container so anybody can run their own instance!
• An API that relays signatures to multiple L2 chains for setting reverse records. This feature is only on testnet right now, but building the API now could lead to it being a core piece of ENS infrastructure when it's launched on mainnet in the coming weeks!
Since this is an open-source infrastructure prize, your project should have clear instructions on how to self-host the service in the GitHub's readme file. A local demo is acceptable since it's intended to self-host, but a deployed version would be even better.
Using ENS on Sepolia or another Ethereum testnet is allowed.
Presenting on Sunday is required! We understand it's difficult, but we simply don't have time to review online submissions while also judging in person.
Every app needs identity, and Durin makes it easy to build that with ENS on L2s. We want to see the smoothest experience you can come up with for creating subnames in your app.
Think about a smart account that creates an ENS subnames (like basenames) at the time of deployment, or AI agents that each have a rich profile powered by ENS text records.
Your project must be functioning with live data on a public URL by the time of submission. You must have deployed a registrar smart contract to use with Durin (instructions in the docs below). Please come to our booth if you have any questions!
Presenting on Sunday is required! We understand it's difficult, but we simply don't have time to review online submissions while also judging in person.
Any type of ENS integration is eligible for this prize. Get creative!
An example of a successful project may be a smart contract wallet that mints an ENS subname on L2 and sets its primary name upon deployment. If you're building an AI project, consider how ENS can be used to name autonomous agents. Come by our booth for help brainstorming ways to integrate ENS into your project!
Your project must be functioning with live data on a public URL by the time of submission. Using ENS on Sepolia or another Ethereum testnet is allowed, but hardcoded data does not count.

Uniswap v4 introduces Hooks—giving developers unprecedented flexibility to customize liquidity pools, fee structures, and trading strategies. Paired with the Superchain’s interop infrastructure and the SuperchainERC20 standard on Unichain, a DeFi-native Ethereum L2 with 200ms transaction times, builders now have a low-latency, high-composability environment to launch the next wave of DeFi innovation.
Projects in this category must implement meaningful integrations using Uniswap v4 Hooks. Whether optimizing LP profitability or introducing new financial mechanisms, the goal is to demonstrate the power of Hooks in DeFi.
Saga offers developers the unique ability to launch their own EVM-compatible Layer 1 blockchains, known as Chainlets, with infinite horizontal scalability. Saga provides recycled gas tokens, enabling developers to implement zero-gas transactions for their users. This infrastructure is particularly well-suited for building high-performance applications like games, entertainment platforms, DeFi protocols, and social applications, where dedicated resources and customizable environments are crucial.
By building on a Saga Chainlet, developers gain the power of a dedicated blockchain without the traditional complexities and costs, unlocking unprecedented scalability and customization for their projects.
