This repository includes 2 smart contracts:

• SKY token
• MkrSky Converter

This is a standard erc20 implementation with regular permit functionality + EIP-1271 smart contract signature validation. In principle PauseProxy and MkrSky would be the only two contracts set as wards(address).

It is a converter between Mkr and Sky (both ways). Using the mint and burn capabilities of both tokens it is possible to exchange one to the other. The exchange rate is 1:rate (value defined as immutable).

Note: if one of the tokens removes mint capabilities to this contract, it means that the path which gives that token to the user won't be available.

Note 2: In the MKR -> SKY conversion, if the user passes a wad amount not multiple of rate, it causes that a dusty value will be lost.
