All prizes can be paid in native EVER tokens, as well as in WEVER (ERC20) on Binance, Polygon, or Ethereum.
Challenge Description
Everscale is an asynchronous blockchain. The development process for Everscale and its technical capabilities have a lot of differences from the common approach in EVM networks. This paradigm can be understood if you think about developers struggling to get into writing code for the multithreaded environment (async/await syntax, computation in a separate thread without blocking the main thread, etc).
Everscale smart contract development is based on the actor model. In simple words, each smart contract is a microservice that interacts with other microservices in an asynchronous way and can spawn other contracts. Of course, all these interactions and deployments are fully onchain.
Everscale has TIP3 (Fungible Token) and TIP4 (Non-Fungible Token) standards, which were developed with consideration of the asynchronous nature of the network and have important differences from their EVM analogs (ERC20 and ERC721).
Each NFT is a separate smart contract.
This allows NFT to be the owner of FT, have its own native balance, etc. Basically, the NFT collection may be extendable and each NFT may contain the logic of any complexity inside.
Onchain NFT metadata
We store the NFT metadata onchain. This allows changing properties of objects (characters/items/traits) onchain. Other contracts can read these properties, allowing you to move all game logic onchain.
NFT indexes
Indexing is substandard for NFT which provides an aligned approach to:
Query all NFTs of the same owner;
Query all NFT collections;
Query all NFT collections of the same creator;
Query all NFTs of the same collection.
Ideas
For this challenge, we propose you implement GameFi logic using FT and NFT standards considering the unique possibilities which Everscale architecture provides. For example, you can take any existing GameFi mechanics from other projects or implement your own.
Onchain game
Implement all game mechanics onchain
Lobby
Implement players' profile and lobby smart contracts (frontend integration is optional, but we strongly encourage you to at least try)
ERC1155 implementation
We have standards similar to ERC20 and ERC721. But there is no ERC1155 analog yet. Propose this standard as well as a reference implementation, taking into account the Everscale concepts.
NFT as collateral
Propose some system where NFT could be locked as collateral in exchange for some value or other NFT, etc.
Grow the NFT
Propose a smart contract system and mechanics where the user can mutate her NFT in a gamified way.
Submission Requirements
A valid submission will include the source code via a GitHub repository linked to your Gitcoin submission, a recorded demo, and an article that explains how the application works. It is expected that most bounty challenges will be won by fully functioning submissions, however, in certain cases, where there is a higher degree of difficulty, projects and payouts will be assessed on progress made.
The project submission deadline is Nov 28th.
Judging Criteria
The following criteria will be used to assess projects:
IMPACT & USEFULNESS: How impactful and useful the submission is in the Everscale ecosystem as a whole
ORIGINALITY, CREATIVITY & INNOVATION: How new and novel the submission is versus existing technologies
MASS USABILITY: How feasible is the idea & how adaptable is it across other integrations
TECHNICAL DIFFICULTY: What is the level of skill or knowledge required to build the submission
CLARITY: How clear or easily understood the documentation, examples, and pitch video is
TEAM DIVERSITY: How diverse are the team’s skill sets & what is the quality of the team formation
