Router Contract

The router contract is the main entry point to the system. It is a write-only contract, which provides functions for every possible MetFi action. For security purposes, it is the only contract with write functions that are callable from outside of the system. Every other smart contract is access controlled and can only be called from within the system. This alone does not make the system completely immune from an exploit but it does significantly reduce the entry vector for potential attacks.
