Mobile withdraw (GOA)

1. Install GNU Taler Wallet (Android / iOS / browser).
2. Open https://bank.hacktivism.ch/ (after DNS + cert work).
3. Login as explorer (or registered user with debt headroom).
4. Withdraw → amount in GOA → open / scan with wallet.
5. Wallet uses DEFAULT_EXCHANGE = exchange.hacktivism.ch.

Exchange must have wire account pointing at this bank (payto + wire gateway credentials) and offline enable-account for /keys withdraw to fully work.

Public landing (withdraw QR)

English intro + QR: https://bank.hacktivism.ch/ → /intro/
Details: configs/bank-landing/. Refresh demo URI: scripts/taler-bank/make-demo-withdraw-qr.sh.

Wallet says “transfer money” — auto-confirm

Normal Taler bank flow after the wallet selects the exchange:

1. Withdrawal status → selected
2. Bank must POST …/withdrawals/$ID/confirm → wires GOA user → exchange
3. Exchange wirewatch sees credit → wallet can finish withdraw

For the demo QR (explorer), automate step 2:

# once
/root/auto-confirm-withdrawals.sh
# loop (e.g. every 4s)
nohup /root/auto-confirm-withdrawals.sh --loop 4 >>/var/log/auto-confirm-withdrawals.log 2>&1 &
