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: - Utility: what APIs can you integrate to pay for everyday use cases, e.g., BitGifty - Personal Finance: Savings dApp focused on stablecoins. What makes your dapp especially useful, and attractive? Check out existing successful savings apps and dapps and understand how you can bring that to MiniPay. 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.

Cel2 Testnet Dango is now live, marking Celo's transition to an Ethereum L2! This bounty is possible to add to your other submissions if you deploy on Celo.

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: * LRTs/LSTs (liquid staking and restaking) * Yield generation * Points farming / looping * Loans * anything new and exciting!

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.

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: - Ease of Use: Ensure the interface is intuitive and easy to navigate. - Visual Appeal: Assess the overall aesthetics, including color scheme and typography. - User Feedback: Check if the application provides clear feedback for user actions. - Consistency: Maintain a consistent design language throughout the application. - Number of Clicks: Amount of clicks a user needs to do in order to perform an action. If using your app feels like magic, then you're on the right track!
