Mobile-first 🤳. EVM compatible 🧩. Carbon negative 🌱 . Celo is a blockchain built for the real world. Build dApps with a great user experience leveraging Celo's lightning fast transactions, low cost, and multi-currency gas fees.
MiniPay is an innovative stablecoin wallet seamlessly integrated into the Opera Mini browser, featuring a built-in dApp discovery page. This integration offers developers a unique opportunity to showcase their apps to over 100 million active users, primarily within African regions.
Create an innovative, user-friendly responsive web app that addresses real world needs in emerging markets. Your application should be deployed on Celo and work inside the MiniPay site tester.
Examples:
Make sure that you watch the tutorial and test out MiniPay. As it is consumer-focused the UX is more user-friendly than the common web3 application. Building for it is almost the same as for any other dApp though. You only need to add a line of code as well as use wagmi or viem in the FE to be eligible for this prize. If you use the MiniPay template of the Celo Composer it will already come with the necessary setup so, you will just have to build mobile-first (UX concept) to be eligible for the prize.
Onchain funding allows for coordinated allocation of capital. This is particularly useful in scenarios where it's necessary to have shared agreement across a global network on how to spend collective funds. These tools can be used by DAOs for treasury management, governments for public goods funding, and even global corporations for combating climate change.
Celo is the home to various onchain tools and protocols that streamline the process for tracking, evaluating, and funding what matters. We are looking for the best dApp that makes it simple for everyday users to leverage these novel onchain funding mechanisms.

EAS is an open-source public good for making attestations onchain or offchain about anything. EAS is natively integrated into the OP Stack and used by OP, Gitcoin, Coinbase, and more for making attestations. Attestations are simply digital signatures on structured pieces of data used to build more trust online and onchain. Any time a structured piece of data that's signed by an entity would add value or build more trust in your product's interactions, attestations can play a role. These actions are typically akin to attesting (vouching, verifying, voting, authenticating, claiming, recording, certifying, confirming, declaring, saying, et.al).
There are several dev tools available to help you build quickly and easily. We're proud that EAS is frequently complemented by ETHGlobal builders on our documentation and tooling. If you ever need help, just reach out!
Show the world how the Superchain can decentralize more than just money and assets. Build an impactful real-world use case that leverages attestations to bridge our onchain and offline worlds. The top three teams with the most impactful and pragmatic projects will be rewarded.
Need some ideas? Think about real-world applications that transform outdated systems into transparent and trustworthy experiences. Move beyond simply transferring data from an SQL database to a blockchain. Solve real problems for real people by creating more trustful systems using attestations.
Here are a few thought starters: Securely manage title registries for land, cars, or other assets to ensure clear ownership and accessibility. Build a privacy-preserving voting system for local polls, elections, or community decisions. Use attestations to authenticate luxury goods. Attest to the provenance of information and creator content, such as music rights or intellectual property. Create a digital notary service. Show how attestations and AI can work together to combat misinformation. Improve onchain commerce with attestations. Create new healthcare experiences with privacy-preserving attestations for medical records, prescription redemption, or other. Develop a supply chain solution that ensures the authenticity and origin of materials like organic cotton or food.
The real-world use cases are endless. We're excited to see what you build.
It must generate attestations using existing or new schemas. It’s a problem worth solving with blockchain that's better than existing systems and experiences. Use privacy-preserving tech when appropriate (zk proofs, offchain attestations, et.al). Use the EAS contracts on Base or Optimism.
We want to help builders build faster. The top three teams that develop the most impactful and practical developer tools for building on EAS will be rewarded.
Need some ideas? Create a library of React components for making or displaying attestations. Develop tools for users to store and manage offchain attestations locally. Create templates or tutorials for common attestation use cases. Build an analytics dashboard for attestation usage, performance, and trends. Develop an AI agent trained on EAS to act as DevRel support. Improve the schema creation and coordination process. Generate zero-knowledge proofs from attestations. Create a developer playground integrating the API and other tooling with sample contracts. Develop a marketplace for attestation-related tools like document signing. Enhance compatibility between attestations and Farcaster Frames with a new library or tool.
It must be a working developer tool upon submission. Clearly define the purpose and utility of your tool. Be passionate about helping other builders build.

Blockscout is a full-featured, open-source block explorer supporting chains throughout the ecosystem. Use Blockscout in the same way you use other explorers - to track transactions & addresses, verify and interact with smart contracts, and connect with APIs to enable application functionality. There are several APIs available including RPC endpoints (which can easily substituted for any Etherscan calls), ETH RPC endpoints, a GraphQL interface, and REST API endpoints.
We need more people using open-source, transparent explorers like Blockscout instead of closed source scanners! Apps can incorporate Blockscout's robust APIs and link to Blockscout for checking transactions, addresses, tokens, and more. Often this is as simple as replacing an existing Etherscan url with the Blockscout one. Use Blockscout in your hackathon project and/or verify your contracts with Blockscout, then show us in your presentation, and you're eligible to share in the prize. It's that easy!
We want to see how your project incorporates Blockscout. When applying for this bounty, please provide links/screenshots and clearly state how you used Blockscout with your project. You can complete any of these items to be eligible.
Use Blockscout instead of Etherscan or another explorer in your app. Typically this means using the Blockscout APIs and linking to Blockscout for users interacting with your app (ie transaction links should go to Blockscout rather than another explorer) but you can be creative! We have a REST API, GraphQL, and standardized RPC API endpoints available for use - no key required!
Verify your smart contract(s) using Blockscout. There are several ways to do this including manually with the Blockscout UI, via API, or with tools like Hardhat or Foundry.
Show Blockscout in your presentation - how you used it with your project and when checking any resulting transactions.
Prepare and submit your DApp which includes Blockscout links to the DAppscout marketplace.

Mode is the DeFi layer 2 part of the Superchain. Built using the OP Stack, it ensures EVM compatibility, making it seamless for developers familiar with Ethereum. Our ecosystem focuses on onchain finance and innovations in decentralized finance (DeFi). As a layer 2, Mode operates with exceptionally low fees, allowing users to experiment and innovate freely on our chain.
If you're looking to build a DeFi project and seek hands-on support from the ecosystem you deploy to, Mode is the optimal choice!
This prize aims to reward the best DeFi application and innovation. We are looking for devs that want to create and test new economic systems for users. Just a fork of something that already exists it's not enough, but valid if there are enough changes to the base code. We want original ideas that focus on the end user for good UX and a solid economic system behind it.
Anything surrounding DeFi is valid, some examples of interesting things are:
There is no need to finish all the working code, but the main features need to be coded and working. In case the code is not 100% finished, there needs to be an explanation clearly showing that the project is technically possible to solve and the team has the capabilities to do so.
Innovation on the product needs to be there. Something new or a combination of existing concepts to create something that has not been implemented before.
The contracts need to be deployed on Mode testnet or mainnet. If the app is multchain, Mode needs to be included and should make sense to have Mode in the list.
Artificial Intelligence (AI) is here to change a lot of industries, and at Mode we want to see creative uses of AI mixed with DeFi. This can be done in several ways and there are already a lot of teams working on products that would improve the user experience in DeFi with the help of AI.
This prize will go to the projects that combine AI with DeFi in a way that makes sense and brings actual value to the end user. Even using an LLM or a chatbot could be interesting to see, if correctly built and if it changes the normal DeFi experience to improve it.
In case there is only one good quality AI x DeFi project, we'll give both prizes to the same winner.
AI needs to be implemented as a key feature or improvement of the project. If the project integrates an AI API like the chatGPT one, there needs to be an added value to the project and the integration needs to make sense.
The AI implemented can also be integrated as a learning algorithm for your project. There are several ways to implement AI and machine learning into a project, we're open to options but it needs to make sense and hace a direct impact in the user experience.
The contracts need to be deployed on Mode testnet or mainnet. If the app is multchain, Mode needs to be included and should make sense to have Mode in the list.
At Mode, we really value user experience and we want to optimize the experience for users while interacting with DeFi. That is why we consider low fees, account abstraction, paymasters, and more, really necessary to create the best experiences.
This prize aims to reward the best UX/UI focused on DeFi. We want to see a smooth working dapp that shows how to implement all the new technologies and standards developed in the past few years to create the ultimate user experience.
We will evaluate things like:
If using your app feels like magic, then you're on the right track!
The evaluation will be performed on the developed app, no designs or figma are accepted for the final judging. If you want to show some designs we'll consider them for future development but the UX/UI analysis will be done on the coded app.
The app can be a web app or a mobile app, both are fine.
This will be an introductory workshop to know what Mode is, where are the main resources for developers and also a ...
