What other testnet lets you interact across chains and still keeps perfect track of your activity?

I’ve been testing the @union_build Testnet since January and recently did a few transactions, moving assets from Sei to BSC, and back again. 

I already knew how Union handles things, updates don’t reflect instantly. It works asynchronously, so I waited. 

The next day, I checked back, and everything lined up. My XP had synced exactly with the actions I took.

Still testing and tracking how Union is building across chains, carefully and with purpose.

I was hoping they would include Aptos chain in the Testnet, and I believe it could still happen before it ends.
