# Nakamapes Optimization

    - `Calldata` can be used instead of `memory` to save gas cost, `public` can be changed to `external`

    - Custom ``revert`` errors an be used to minimize gas cost

    - ```Use shorter require()/revert() strings``` which can help reduce gas cost

    - For checks of _mintAmount we can replace ```>0``` to ```!0``` since overflow/underflow checks are part of the solidity version
