Learn to write, test, and deploy an ERC-20 token on the Ethereum Sepolia testnet using OpenZeppelin, Hardhat, or Remix, and GetBlock's instant RPC endpoints without needing a personal node.
To get started, install NodeJS and Hardhat, set up your project, and integrate OpenZeppelin libraries to leverage secure and audited contracts.
Write the ERC-20 contract specifying the name, symbol, and initial supply, and customize transfer and provisioning functions according to your custom software requirements.
Run local tests with Hardhat to ensure the correct behavior of your token and validate transfer, balance, and permission scenarios.
Configure the connection to the Sepolia testnet using the endpoints designed in GetBlock and add your project key to the Hardhat configuration file to deploy your contract without managing your own node.
Once deployed, verify the contract address and test the mint, burn, and transfer functions from Remix or Hardhat scripts to ensure proper operation.
