catERC20

This is an optimised implementation of xERC20 (or ERC-7281). It is inspired by the https://github.com/defi-wonderland/xERC20.

Improvements

• Burns are subtracted from mint limit.
• Lockbox is set as a bridge rather than as a lockbox while being fully compatible with ERC-7281.
• Burns are unlimited. The burn limit serves no protection since Bridge could collect tokens from users anyway.
• Single slot bridge config, with major gas improvements.

Minor Differences

• No Factory ownership on contract.
• Simplified limit logic for easier auditing.
