[NEAR] Building Mobile DApps on NEAR protocol

Through simple, secure, and scalable technology, NEAR empowers millions to invent and explore new experience.

There are now a large number of DApps on the Web platform, but seems to be relatively few DApps that support mobile platforms.

Blockchain still has a lot of room for DApps built for mobile platforms. Recently SweatCoin bulit on NEAR have successfully closed a $13M investment round.

In this challenge, we call for DApps that running well on mobile platforms. The DApps can be native Android or iOS applications, or mobile-compatible Web applications.

Use your imagination! You can build fun mini-games using the NEAR contract as a scoreboard, mint NFTs for winners of a competition, or build DApps that supports login with your NEAR account.

Let’s BUIDL!

[Mina] Building a zkApp on Mina with SnarkyJS

Mina Foundation will provide bonuses to reward the technical development of zkapp ecological projects. Tracks include but are not limited to: wallets, tools, encryption, APIs, and various privacy smart contract use cases, including digital identity and privacy, Internet of Things, game data storage, and finance.

In this funding activity, our philosophy is to encourage students to use the features of zero-knowledge proof and zkApp to practically solve some practical problems in the blockchain world. We do not require developers to complete the code development of the entire project. Only a relatively complete project plan needs to be submitted (Note: The more complete the project information submission, the higher the probability of being selected).
