Mean Finance Swappers
This repository holds Mean's swapping infra. We can divide it into 4 different components:
1. The Swapper Registry
This contract will function as a registry for all allowed swappers and allowance targets. Since we will allow swappers to take arbitrary calls and approve arbitrary addresses, we need to have an allowlist. If we didn't, then we could easily get attacked.
2. The Swap Adapter
This abstract contract will give contracts that implement it swapping capabilities. It will make integration with swappers much easier, as it will handle validations, approvals, execution and transfers.
3. Swap Extensions
These are different versions of the Swap Adapter, built for different scenarios. Other contracts can simply implement these extensions and they will support swapping out of the box.
4. The Swap Proxy
This contract implements all swap extensions, so it can be used by EOAs or other contracts that do not have the extensions.
