A step-by-step tutorial for deploying an ERC-20 token called EduCoin on a private blockchain with zero gas fees. Using OpenZeppelin for secure contract inheritance and Remix IDE for development, the guide walks through writing a Solidity smart contract, deploying it via MetaMask's Injected Provider, and testing token transfers between parent and child wallets. The token is designed as a household reward system for gamified education, with the owner holding exclusive minting rights via the onlyOwner modifier.
