Well, nice.

I have a few questions, if you don't mind.

1. Regarding "Autonomous Worlds Ltd (EU registered Ltd), the company that maintains and develops the open source Xaya platform, will provide a swap for verified users."

Why only verified users? What prevents you from doing the CHI->WCHI swap automatically for everyone? Like if someone is sending CHI coins to a designated address, you automatically send WCHI to his ETH address? This is the way swaps are typically done - no need for user verification (or KYC) whatsoever!

2. I understand you will burn users CHI and issue WCHI from a reserve (“holding addresses”). That part is clear. However I am not sure how are you going to swap the WCHI to CHI when needed? CHI cannot be generated on demand, so... what? Will the WCHI<->CHI swap be just one directional, with no way to get CHI back?

3. What is the use for WCHI besides trading? CHI is a main token of the Xaya blockchain, which also holds the whole gameplay. So CHI can be used on that blockchain somehow. With WCHI it is not clear what could be done with it. What part of Xaya technology be used on Ethereum, and how?
