This is a custom ERC20 token contract with access control using OpenZeppelin's libraries:
Inheritance:
ERC20: Standard token functionality (transfers, balances, etc.). AccessControl: Role-based permissions (admin/minter roles). Roles:
DEFAULT_ADMIN_ROLE: Granted to the deployer (can manage roles). MINTER_ROLE: Granted to the deployer (can mint new tokens). Key Functions:
constructor(): Sets token name (My Cyfrin CLF Token) and symbol (CLF). mint(): Only callable by MINTER_ROLE; creates new tokens and assigns them to to. Security:
Uses OpenZeppelin’s audited contracts. Role checks prevent unauthorized minting.
