Coincheck clarifies after suspending all cryptocurrency withdrawals: No hack occurred; the cause was an outage at an external service.
In the early hours of Thursday, November 5, 2026, Coincheck decided to suspend all cryptocurrency deposits after a third-party analytics service it uses to screen transactions stopped working. Coincheck said the outage was not a security breach, did not involve customer funds, and no unauthorized access had been detected.
· The problem was with an external screening process the exchange relies on, not a breach of its own systems.
· The company explicitly denied that funds were affected, but did not provide a timeline for resuming service.
When an exchange suspends withdrawals, would you check its official announcement first or look at on-chain fund movements?
