The project includes an ERC20 token contract with the following features:
-
Role-Based Access Control: Implements OpenZeppelin's AccessControlDefaultAdminRules
DEFAULT_ADMIN_ROLE: Can enable transfers and manage other rolesMINTER_ROLE: Can mint new tokensTRANSFER_ROLE: Can transfer tokens before transfers are enabled
-
Controlled Token Transfers:
- Transfers are initially disabled
- Only addresses with
TRANSFER_ROLE, the owner, or minting operations can transfer tokens when transfers are disabled - Transfers can be enabled by admin (one-way operation - cannot be disabled once enabled)
-
Token Minting:
- Controlled minting through
MINTER_ROLE - No maximum supply cap
- Controlled minting through
- OpenZeppelin's ERC20
- OpenZeppelin's ERC20Burnable
- OpenZeppelin's AccessControlDefaultAdminRules
mint(address to, uint256 amount): AllowsMINTER_ROLEto mint new tokensenableTransfers(): Allows admin to enable transfers for all holdersburn(uint256 amount): Allows token holders to burn their tokens (inherited from ERC20Burnable)
- Role-based access control for critical functions
- Protected transfer functionality until explicitly enabled
- Default admin rules for secure role management
The smart contracts have been thoroughly tested with 100% coverage across all metrics:
- Lines: 100% (8/8 lines)
- Statements: 100% (5/5 statements)
- Branches: 100% (3/3 branches)
- Functions: 100% (3/3 functions)
Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.
Foundry consists of:
- Forge: Ethereum testing framework (like Truffle, Hardhat and DappTools).
- Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
- Anvil: Local Ethereum node, akin to Ganache, Hardhat Network.
- Chisel: Fast, utilitarian, and verbose solidity REPL.
