Can someone clarify the transition from Ethereum to Cosmos for me?  I didn't find the info in the latest white paper (v1.3) to be entirely clear.

Cosmos is all about creating interoperability between different block-chains using different technology. Is Sentinel actually being:

• recoded from ERC20 to Cosmos based-code?
• being adapted to interact with the Cosmos hub and will remain ERC20?
• something else?

Thanks.
