That would be very sad... Leodex looked awesome to bridge coins in and out of Hive. I hope they can get the Keychain integration back at some point: maybe if the altseason comes, more people would be interested to use a bridge like that.

manually bridge LEO over to Arbitrum

Yeah, this looks way less user-friendly... and there would be a lot of fees/slippage involved, I guess.

Btw, thanks for all these info!
