Hardhat

Welcome to the repository where I've embarked on my journey into the world of cryptocurrencies and smart contracts. This project is built on the Ethereum Virtual Machine (EVM) and has been deployed on the Sepolia Testnet using the powerful Hardhat framework. But you better check my another work, My decentralized application on zkSync Era Testnet. https://github.com/disiminar/zkSync-test-proj

Here are some specifications of the project:

• In tests, I used ethers.js to interact with the Ethereum contract, and I used Mocha as my test runner.
• My test token info:
  • There is a fixed total supply of tokens that can't be changed.
  • The entire supply is assigned to the address that deploys the contract.
  • Anyone can receive tokens.
  • Anyone with at least one token can transfer tokens.
  • The token is non-divisible. You can transfer 1, 2, 3 or 37 tokens but not 2.5.
  • Link to transaction of smart-contract creation on Sepolia testnet scan here
• I am using Infura to get API private key for deploying smart-contract on real network (testnet)
• In order not to waste time on the front-end, I used a ready-made example from the Hardhat team (Hardhat Boilerplate). link on repository

After this, i can transfer tokens by using the Boilerplate GUI on localhost, or console.

Example of output:
