Thanks.

One thing i understand even less now is, i made a transaction on B3, i opened a pack. it needs to be stored somewhere on B3 network before it is written to Base, because it needs to be batched with all other transactions. The same needs to happen on Base before it goes to Ethereum. There needs to be some kind of infrastructure running for that to happen. There are no classics decentralized nodes responsible for that, so is Coinbase running it?
I assume it must be recorded somewhere as you can't batch stuff in real time :)

ignore the terminology, i probably missed half of how things should be called.
