奖金池分配

Grand Prize - XCM Cross-Chain Explorer

1st Place - $20,000

2nd Place - $5,000

XCM is a foundational new technology of Polkadot that allows heterogeneous blockchains to interoperate and seamlessly transfer value. XCM functionality recently debuted on Moonriver with the introduction of the XC-20 standard, a Substrate-native asset that conforms to ERC-20 standards. xcKSM, or KSM migrated from the Kusama Relay Chain, is the first XC-20 to launch on Moonriver. Currently, transferring assets via XCM between relay chain and parachain can be a frustrating experience because the information displayed in block explorers is limited and disjointed. For example, you might see a transaction that initiated your XCM transfer but it is not clear 1) that it is an XCM transaction and 2) the destination of the transfer. Your challenge is to build an explorer that tracks the status of a user’s assets and reflects accurate locations for assets transferred via XCM.

The main idea is to provide a nice UI and improve the UX for end users using XCM transfers. For example, put in your Ethereum Tx hash, or Substrate tx hash, or your address, and you’ll get a list of all the XCM you’ve done, with a link to the Event-ID on the target chain.

NFTs

NFT Collection Showcase DApp

1st Place - $7,000

2nd Place - $2,500

Build an app that allows users to showcase their NFTs on Moonriver. The best project submissions will: -- Support as many NFT collections on Moonriver as possible. -- Allow users to create and share a user-friendly link with their friends. For example, mynfts.com/KevinPurestake Instead of, mynfts.com/address/0x2c507D8A3517799061c00cd6e4868C62210b647f -- Display relevant NFT Metadata and traits such as supply, rarity, tokenID, etc.

NFT Creation and Deployment DApp

1st Place - $7,000

2nd Place - $2,500

Build an application that allows non-technical users to create and deploy NFTs to Moonbeam via a simple UI. Users should be able to upload image files for each NFT and specify various characteristics such as rarity. The best project submissions will:

Ensure the NFT image files are hosted on a decentralized service.
Allow users to set traits such as rarity and other characteristics.
Have a transfer functionality to allow NFTs to be transferred via web ui.
Feel free to use Pinata to help build your application.

Indexers Core Bounty

Integrate On-Chain Data with the Help of Indexers - $5,000

Retrieving data from blockchains can be a complex process but fortunately there are solutions such as Covalent API, TheGraph, and Subquery that make it a much more enjoyable experience. For example, to get a user’s ERC-20 token balances, you’d typically need to query the blockchain with every single token contract address to confirm a user’s balance. Instead, Covalent API allows you to do this in a single API call. Subquery allows you to query EVM and Substrate data with a unified manner. The Graph is a well-known decentralized indexing protocol that can efficiently store data into various indices called Subgraphs.

The best submissions for this bounty will:

Use an Indexer to provide a key piece of data in their application.
Be elegantly designed and intuitive for the end-user.

Gaming

Launch a Game on Moonriver

1st Place - $7,000

2nd Place - $2,500

Moonriver is fast, efficient, and interoperable, making it a perfect destination for gaming apps. Web3.unity is ChainSafe’s new open-source gaming SDK that makes it easy to integrate blockchain data into the Unity gaming engine. Web3.unity provides everything you need to power your gaming dApps and includes built-in wallet authentication among its many features. ChainSafe has published a comprehensive series of YouTube tutorials that demonstrates the capabilities of the SDK or you can check out the SDK docs here. To clarify, any gaming dApp is eligible for this bounty — you aren’t required to use ChainSafe’s gaming SDK to qualify.

Huobi Incubator Moonshots

Huobi Incubator Moonshot Bounties - 2 Awards of $10,000

If you’re building a unique DApp that doesn’t fit neatly into one of the already specified bounties, then this is the bounty for you! The only requirement here is that you haven’t submitted your project to other bounties.
