From f1b411ecb8436fa0fc3a77bf0cf2bf6f5bd985d8 Mon Sep 17 00:00:00 2001 From: Russell Ballestrini Date: Thu, 25 Sep 2025 13:22:36 -0400 Subject: [PATCH] Implement passive monitoring for late crypto payments - Add scan_wallet_for_late_payments() that checks all wallet transactions - Match transactions to payments by address (DOGE) or subaddress (XMR) - Process late payments to expired/cancelled quotes automatically - Add database indexes for efficient payment lookups - Add comprehensive unit and integration tests This allows the system to detect and refund payments that arrive after quotes expire, without actively monitoring every expired payment forever. --- make_post_sell/lib/crypto_watcher.py | 95 ++++++ ...add_indexes_for_crypto_payment_address_.py | 36 +++ make_post_sell/tests/test_crypto_watcher.py | 295 +++++++++++++++++- make_post_sell/views/crypto.py | 4 +- 4 files changed, 428 insertions(+), 2 deletions(-) create mode 100644 make_post_sell/scripts/alembic/versions/5997b993482e_add_indexes_for_crypto_payment_address_.py diff --git a/make_post_sell/lib/crypto_watcher.py b/make_post_sell/lib/crypto_watcher.py index fd70213..3f53b97 100644 --- a/make_post_sell/lib/crypto_watcher.py +++ b/make_post_sell/lib/crypto_watcher.py @@ -1523,12 +1523,107 @@ def update_payment_confirmations_only(client, crypto_payment, coin_type): ) +def scan_wallet_for_late_payments(request, settings): + """ + Scan wallet for ALL incoming transactions and match them to payments. + This catches late payments to expired quotes that aren't actively monitored. + """ + logger.info("Starting wallet scan for late payments") + db = request.dbsession + + #
