# Auto-confirm bank withdrawals once the wallet has selected exchange+reserve.

# Required for regional x-taler-bank: confirm wires GOA from user → exchange.

# Auto-confirm bank withdrawals for the community demo pool ONLY.

# Only account: explorer (override only if you really mean another pool user
|
||||
# via BANK_USER, but still confirms with that user's token only — never
|

# confirms other customers' withdrawals).
