Getting out: the queue and the caps

Where does the cash that pays withdrawal tickets come from?

• The protocol's treasury, which tops up the queue
• Borrowers repaying, new deposits and liquidations
• Other ticket holders, who give up part of their tickets

A reserve's withdrawal cap capacity is set to 0. What does that mean?

• Nobody can withdraw at all
• The cap is switched off, so it sets no limit
• Only queued tickets can be paid
