Not a problem. Would be an improvement.

hehe,

fix never a problem nobody has :D

But improvements are always nice. Have you an example for me of what could be done better?

I could imagine some more complex trades ( sandwich swaps) or something else that relies on each other.

But not sure I riding the right horse :d

Exchanges mostly. When you deposit to an exchange they want to make sure the deposit really happened before letting you trade or withdraw. Most other transactions can just wait the minute, or can accept the risk.

Could also include decentralized exchange/bridge/apps, except there aren't really smart contracts on Hive so that mostly doesn't exist.

so it's more a foundation for future stuff. Not bad!
