Creation of a NFT on an EVM-compatible blockchain.

🎨Explore this simple example of deploying an NFT using Hardhat and TypeScript on the Sepolia test network. Ideal for those diving into NFT development.🚀

A decentralized Delegative Democracy structure on Ethereum, allowing people to access proposals and new protocols and vote on it. Built using Solidity, Hardhat, TS.

A test project given by a stealth startup to validate ✍️ my smart contract skills. The task was to create a gasless marketplace 🛒. The sellers can list the NFT for sale against a specified no of ERC-20 token called GEM's 💰 and whitelist some buyers.

So the whitelisted buyers will be able to transfer the required GEM's 💰 and buy's the NFT. And other task was to allow user to burn their ERC-721 token to upgrade to ERC-1155 token.

Furthermore, gasless ⛽ transaction is also implemented using ERC-2771. The relay is created using NodeJS, and it also tracks the amount of gas spend in a database for analytics.

Progetto DEMO che, tramite l'uso della libreria Waffle JS, esegue il testing di alcuni semplici Smart Contracts.
