Modify the main token contract ./contracts/TanganyTestToken.sol to deploy a ERC20 token or replace it with a custom contract. Make sure the contract file name is referenced correctly in ./migrations/2_deploy_contract.js
Each deployment environment has a different set of mandatory environment variables. Add the secrets required for the deployment environment to .env
Make sure to provide the 64 character long hexa-decimal PRIVATE_KEY. The associated address will inherit the tokens created by the contract deployment.
Deploy the smart contract to the desired environment with the provided commands. The address of the deployed contract will be printed to the console output:
