- Solidity - an object-oriented, high-level language for implementing smart contracts
- OpenZeppelin - a library for secure smart contract development
- Hardhat - a development environment to compile, deploy, test, and debug the process of building smart contracts and dApps (can also use Waffle)
- Web3.js - a collection of libraries that allow you to interact with a local or remote ethereum node using HTTP, IPC or WebSocket (can also use ethers.js)
- Chai and Mocha - the most advanced framework for testing smart contracts (can also use Waffle)
- Polygon - solves common blockchain pain points, offering low gas fees and high speeds without sacrificing security. For local tests is using Polygon Mumbai
- Infura - runs ethereum nodes and provides access to them via api to eliminate the need to run and update your own infrastructure -IPFS - a peer-to-peer hypermedia protocol designed to preserve and grow humanity's knowledge by making the web upgradeable, resilient, and more open
- React - is an open-source JavaScript framework, designed for building apps on multiple platforms like iOS, Android, and also web applications, utilizing the very same code base. It is based on React, and it brings all its glory to mobile app development.
- Tailwind - a utility-first CSS framework packed with classes like flex, pt-4, text-center and rotate-90 that can be composed to build any design, directly in your markup
The smart contracts inherit next SC from the openzeppelin libraries:
Ownable.sol - access control
ReentrancyGuard.sol - reentrancy guard pattern
SafeMath.sol - to prevent ower/under flows
Address.sol - to work with address types
Counters.sol -
To run project you shold install this
https://hardhat.org/getting-started/To run tests
npx hardhat testTo deploy to local network
npx hardhat node
npx hardhat run scripts/deploy.js --network localhostTo run on localhost
npm run startor
npm run build
npm run startPrice
1 ETH = 50 MARIIA COIN
The price in MRSNLK for the NFT will be calculated automatically. If the price in ETH in 0.0001 eth, the price in MRSNLK will be 0.005 MRSNLK.
