The Althea routing and billing software (bandwidth selling code) has been using DAI for a very long time since before USDC existed.
As such the Althea community has a good relationship with SKY/Maker and the foundation did a joint press release with them a little while ago. Being the first in the Cosmos ecosystem with Sky tokens will draw swap and arb volume.
Adding an Althea/USDC pool wouldn’t be much trouble, since pools are all fee funded.
