Not likely. You can use it in your webwallet which is LNBits, but for in game, because I'm working with a lot of 3rd party plugins designed for a virtual economy there are a lot of balance checks and whatnot. The flow is a bit complicated to get right so it works like any other seamless economy so a local node with custodial wallets were a requirement. It's fast though.

Custodial wallets is where ecash shines. How much have you explored Cashu?
I'm running on LNBits. I know it well. I jsut don't want to complicate the ease of use of the wallets. There may be a time for it, but it will not have much value add. I want to get nip-05 registration [playername]@minecraftstr.com first for instance, but there are other things even before that.
