On November 27, South Korea’s leading crypto exchange Upbit abruptly paused deposits and withdrawals after detecting an abnormal outflow of approximately $38.5 million on the Solana network. The platform’s monitoring systems flagged a large, unauthorized asset transfer to an unknown wallet, prompting immediate action to prevent further potential loss.
According to Upbit’s statement, the funds were moved without clear authorization, and the transaction patterns differed from normal user behavior. This raised internal alarms, leading to the suspension of key services across the exchange for further investigation.
Upbit Promises to Cover All Losses
While the abnormal transaction raised concerns across the crypto community, Upbit reassured users that their assets are safe. The company stated it would cover the full amount lost due to the outflow, reinforcing its commitment to customer protection.
This assurance helped stabilize user sentiment amid growing concerns about blockchain security. Many industry watchers have praised Upbit’s swift response and transparent communication during the incident.
Upbit’s investigation into the Solana-related anomaly is ongoing. It’s still unclear whether the outflow was the result of a hack, an internal error, or an exploit.

What’s Next for Upbit and Solana Users?
This event puts blockchain security under the spotlight once again, especially for exchanges handling large volumes of transactions. It also raises questions about vulnerabilities within smart contract platforms and wallet monitoring systems.
As of now, Upbit has not disclosed a timeline for resuming full service but emphasized that deposits and withdrawals will reopen only once they ensure the platform’s integrity.
This incident serves as a critical reminder of the importance of rigorous security protocols in the fast-paced crypto ecosystem.
