Where does the 3,623.19 ERA floor come from?

The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending ERA, and that one goes to the blockchain, not to us.

Which network will GRAM arrive in?

Gram (Toncoin) leaves in its own TON network — a plain GRAM address is all you need. Some exchanges and wallets also need a Comment (Memo).

What if the rate moves while I am paying?

The rate is pinned to the order and does not move while the order is alive. It can be recalculated if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
