Basic ERC-20 contract designed to be inherited and extended. Leveraging native overflow checks in solc 0.8 to simplify ERC-20 implementation. It should be noted that this ERC-20 implementation does not include some functionality that is commonly used in other tokens, such as:

• address(0) checks on _transfer
• push
• pull

This was intentional, as this ERC-20 was intended to have the minimum functionality necessary, allowing for maximum extendability and customizability.

This token implementation includes ERC-2612 permit capability as well as increaseAllowance and decreaseAllowance functions.

This project was built using Foundry. Refer to installation instructions here.

git clone git@github.com:maple-labs/erc20.git
cd erc20
forge install

• To run all tests: forge test
• To run specific tests: forge test --match <test_name>

./scripts/test.sh is used to enable Foundry profile usage with the -p flag. Profiles are used to specify the number of fuzz runs.
