Value you can move
Five conditions about moving value. The interesting thing about them is that they have to be true simultaneously rather than in turn.
Stage E is where the map develops a property none of the earlier stages have. In stages A to D a condition, once true, tends to stay true. You do not wake up with a different browser. In stage E, conditions expire. A balance that was spendable an hour ago may not be. A quote that was current at breakfast is not current now. A fee estimate is a statement about the last few minutes, not about today.
That is why the stage does not end in this stage. It ends at a total that is covered at the moment you press, one card into the next stage, which exists precisely to say that all of stage E has to hold at once rather than each part holding at some point in the past.
What enters this stage
Three arrows arrive. Machine control and the single copy question both feed the custody condition, which is stage A reaching four stages forward. Logging in a second time feeds two conditions here, because both the denomination question and the deposit destination question are things you learn from a session rather than from a page.
What leaves this stage
Two arrows leave, and both go to the same place. The deposit address condition and the fee condition both feed the simultaneity card in stage F. Nothing else in the map waits on stage E directly, which makes the stage look smaller than it is. Follow the arrow one step further and it is holding up the entire parcel stage and most of the closing stage.
The order the conditions are usually discovered in
That column on the right is the argument for reading the stage before you need it rather than during. Four of the five conditions announce themselves late, and the fifth does not announce itself at all.
No figures appear in this stage
There are no fee amounts here, no confirmation counts, no exchange rates and no prices, because any number of that kind would be wrong by the time it was read and would be quoted back as if it were not. Where a number is genuinely needed, the card says where to read it from rather than what it is. About this site sets out the rest of what is deliberately absent.
