# Transaction confirmations

> Blockchain confirmation and status polling behavior.

## Status polling

Meum uses a background **payment monitor** to detect on-chain payments against checkout deposit addresses.

When you call `GET /v1/invoices/{id}/status` on an open invoice with a deposit address, an on-demand poll is also triggered.
