Does ERC-6672 only has interface?

Why doesn't the newly passed standard ERC-6672 have implementations for each function?

The implementation of ERC proposals is not essential . Taking ERC-6672 as an example, follow the interface of this standard is sufficient, and implementations can be adjusted according to the specific requirements of each project.

Thanks for your interest on ERC-6672. The reference implementation you can find in the asset folder.

You can check RE:DREAMER Website ( and join our Discord for more updates. We will soon create a ERC-6672 Working Group on Telegram to support developers which are interested in using ERC-6672.
