Prize details

Use the Yellow SDK and Nitrolite protocol to build a mini-app or feature that showcases instant, session-based transactions - all happening off-chain and settling on-chain when needed. 💥 How to participate - Integrate the Yellow SDK, connect to the Nitrolite test environment and create a wallet session. - Implement off-chain logic: simulate sending or spending assets instantly between users or in-app actions. - Show on-chain settlement: finalize balances through smart-contract calls when users end their session. 🛍️ Example App Ideas - Trading apps - Prediction market apps - Tipping System: users send 0.01 USDC per like, emoji, or message without gas or delay. - Pay-Per-Use App: charge users per API call, minute, or read action - settle once at the end of session. - Cross-App Wallet: one balance shared across multiple dApps (browser plugin, Telegram mini-app, etc.). 💎 Why Build on Yellow - Gas-free & instant: off-chain state channels = Web2 speed, Web3 security. - Session-based logic: define allowances for in-game or in-app use. - Multi-chain ready: works with all EVM chains; Solana support coming soon.

Qualifications

✅ Qualification Requirements - to qualify for the Yellow Network Prize, your project must: - Use the Yellow SDK / Nitrolite protocol in your submission. - Demonstrate off-chain transaction logic — e.g., instant payments, session-based spending, or settlement finalized via smart contracts. - Deploy or simulate a working prototype showing how Yellow improves transaction speed, UX, or efficiency. - Include a 2–3 minute demo video showing your integration and user flow. - Submit your project under the “Yellow Network” prize track on ETHGlobal and include a repo link. 🏆 Judging Criteria Projects will be evaluated based on: - Problem & Solution: clarity of the problem addressed and creativity of the solution. - Yellow SDK Integration: depth and impact of integration with Yellow technology. - Business Model: clarity and sustainability of the project’s value or revenue model. - Presentation: ability to communicate the idea clearly and persuasively. - Team Potential: team’s skill, passion, and commitment to continue post-hackathon.

Prize details

Any type of ENS integration is eligible for this pool prize, split evenly among all eligible projects. Get creative!

Qualifications

You need to write some code specifically for ENS, even if it's just a couple wagmi hooks. Simply using Rainbowkit does not count. Your demo must be functional and not contain hard-coded values. Upon submission, your project showcase must have a video recording or link to a live demo (ideally both) and the code needs to be open source and accessible on Github or a similar platform.

Most creative use of ENS for DeFi

$1,500

$300 × 5 winners

Prize details

ENS is often thought of as simple name <> address mapping, but really its much more flexible! Names can store arbitrary data via text records, decentralized websites via content hash and more. This prize goes to the most creative application of ENS in DeFi. This could be some sort of swap preferences stored in text records, DEX contracts that are named via ENS, decentralized interfaces or anything else.

Qualifications

It should be obvious how ENS improves your product and is not just implemented as an afterthought. Your demo must be functional and not just include hard-coded values. Upon submission, your project showcase must have a video recording or link to a live demo (ideally both) and the code needs to be open source and accessible on Github or a similar platform.
