@mean-finance/transformers v1.3.0

Mean Transformers

With this repository, we are now defining the concept of dependent tokens. These are tokens that depend on one or more underlying tokens, they can't exist on their own. This concept can apply to some known types of tokens, such as:

• Wrappers (WETH/WMATIC/WBNB)
• ERC-4626 tokens
• LP tokens

In this repository, we will build our Transformers. These are smart contract that knows how to map dependent tokens into their underlying counterparts, and vice-versa. We are doing this so that we can abstract the way tokens can be transformed between each other.

Finally, this repository also contains Mean's "transformers registry". All transformers will be registered to this contract, so that all clients can interact with the registry directly, without having to know all existing transformers.
