# 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).
#
# Run once: auto-confirm-withdrawals.sh
# Loop: auto-confirm-withdrawals.sh --loop [SECS]
#
# Env:
# BANK_URL (default http://127.0.0.1:9012)
# BANK_USER (default explorer) — account that owns the demo withdrawals
# BANK_PASS or /root/bank-explorer-password.txt / /root/bank-${USER}-password.txt
# BANK_USER (default explorer) — must be the pool account
# BANK_PASS or /root/bank-explorer-password.txt
# LANDING_DIR (default /var/www/bank-landing)
# ALLOW_NON_EXPLORER=1 — allow BANK_USER other than explorer (off by default)
