Uphold clears six-day crypto transfer outage, blames outside monitoring partner

Uphold closed the book on its crypto transfer outage Tuesday. The platform's status page marked the incident resolved at 3:50 a.m. ET on Nov. 10 and listed every system as operational, ending a disruption that started Nov. 4.

The company blamed a third-party transaction-monitoring provider for the mess. Fiat deposits, withdrawals and trading kept running normally the whole time, Uphold said, so the pain was concentrated in crypto transfers.

Progress came in stages. By Nov. 5, Uphold said roughly 80% of crypto deposits and withdrawals were going through, with a pile of pending transactions still stuck. A day later, a workaround let deposits resume for most supported assets even as the partner's outage dragged on.

Not everything moved. Delayed deposits and withdrawals on Nov. 6 included CSPR, CCD, KAS, STX, STRK, IOTA and SHX, plus BTC over Lightning and USDC on XRPL, according to the status page.

As late as Nov. 9, Uphold acknowledged transfers were still lagging and more transactions needed review. The platform told users it was working through the backlog and that funds remained safe.

Chief Product Officer Paul Unterberg called the turnaround on Nov. 10 at 8:35 a.m. ET, saying staff had cleared transaction reviews overnight and were reworking how systems flagged them. “The majority of transactions are cleared and I don't anticipate the massive delays anymore,” he wrote.
