ERC20

The test environment is supported by Foundry

This project is intended to implement ERC20 standard using solidity from scratch. The key function of ERC20 includes

• constructor,
• transfer,
• burn,
• mint,
• approve,
• transferFrom,
• increaseAllowance,
• decreaseAllowance，
• permit.
  Also, to evaluate the correctness of my contract, I also designed a few functions to test them.
