| Summary | 0010900: wallet sometimes creates an empty refresh group when not enough denominations were validated, resulting in lost funds | ||||
| Description | The wallet lazily validates denominations offered by the exchange. In some situations (particularly aborted P2P transactions), the wallet doesn't ensure that it has enough validated denominations from the exchange before proceeding with the DB transaction that creates a refresh (where new denominations are selected). This can sometimes lead to refresh transactions with non-zero input but zero output, effectively resulting in lost funds. | ||||

commit beb73940b19ebdc3cc5da42e09d2a946b0c60e7c Author: Florian Dold <florian@dold.me> Date: Wed Jan 14 16:47:17 2026 +0100 wallet-core: fix issue with empty refresh groups In some situations, wallet-core created refresh groups with a non-zero input and zero output. This happened when required output denominations were not validated yet. In this case, wallet-core treated the denominations as absent and wasn't able to create any outputs for the refresh, so a refresh group with empty outputs was created. This was fixed by: * disallowing the creation of refresh groups when there are required denominations that should be validated but aren't validated yet * validating denominations in the background * repairing existing, bad refresh transactions via fixup |
