Practical overview
When it fits
Use it for the documented turtle arcade game and its character marketplace, or consult the repository when exploring its stated Polygon, Chainlink and NFT implementation.
Who it is for
- Players interested in a score-based arcade game with collectible turtle characters.
- NFT users who want to browse or trade the game’s turtle characters.
- Developers examining a JavaScript, React and Phaser DApp with Polygon smart-contract components.
Documented uses
- Play a turtle character through an obstacle-dodging game using left and right arrow keys.
- Earn a randomized turtle NFT by reaching a new score checkpoint.
- Browse owned turtle NFTs and buy or sell characters in the in-app marketplace.
- Review or locally prepare the project's documented DApp stack and testnet configuration.
Requirements & limits
The README describes a browser DApp and a Mumbai testnet setup requiring MetaMask connected to MATIC Mumbai and MATIC tokens. It does not establish current deployment availability.
- The README describes the DApp deployment on MATIC Mumbai Testnet, so its stated network context is testnet rather than evidence of a current mainnet deployment.
- Gameplay ability varies by turtle NFT: left-right movement speed differs between characters.
- The README names nft.storage, IPFS and Filecoin for NFT metadata, with Chainlink oracles relaying an IPFS hash to the contract.
- Repository metadata identifies the project as JavaScript-based and MIT-licensed.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Prepare the DApp for local development
Set up the documented prerequisites and configuration for the local DApp.
Before you start
- NPM and Yarn
- Truffle
- MetaMask browser extension connected to MATIC Mumbai Testnet with MATIC tokens
- Alchemy and Polygonscan API keys
Steps
Install Yarn globally with the command below if it is not installed.
npm install -g yarnInstall Truffle globally with the command below if it is not installed.
npm install -g truffleClone the repository and install its packages with
yarn.Create a
.envfile containing the Polygonscan API key, wallet mnemonic and Polygon Mumbai Alchemy RPC URL, using the variable names shown in the README.
Expected outcome
The documented dependencies and environment configuration for local DApp development are prepared; the README’s subsequent launch step is `yarn start`.
Guide limitations
- The README requires Mumbai testnet MATIC and API keys; this is a testnet-oriented setup.
- The wallet mnemonic is sensitive and should not be exposed.
- The repository’s clone instructions name a different GitHub URL from the project repository, so confirm the intended source before cloning.
