Leading South Korean cryptocurrency exchange Upbit has announced two significant operational pauses affecting its services. The first is a planned, full-platform server maintenance scheduled for April 12, 2025, which will halt all trading, deposits, and withdrawals for six hours. The second is an immediate, targeted suspension of deposit and withdrawal services for Polygon (POL) due to an upcoming network hard fork.
The comprehensive server maintenance is set for Friday, April 12, 2025, from 5:00 p.m. to 11:00 p.m. UTC. During this window, all services on Upbit will be suspended, including Korean won (KRW) and cryptocurrency deposits/withdrawals, spot trading, and order book activity. The exchange has advised users to complete urgent transactions beforehand. This maintenance is described as a standard industry practice for major infrastructure upgrades, aimed at bolstering long-term system stability, security, and scalability for its millions of users.
Separately, Upbit has suspended all deposit and withdrawal services for Polygon (POL) starting at 12:00 p.m. UTC on April 8, 2025. This action is a direct response to an upcoming critical network hard fork on the Polygon blockchain. The exchange stated that trading for POL against other cryptocurrencies will continue uninterrupted, but the movement of tokens onto and off the platform is halted. Services will resume once the network upgrade stabilizes and Upbit completes its system validation, a process that typically takes several hours post-upgrade.
Industry analysts view these planned suspensions as signs of responsible platform management. For the full maintenance, experts note that predictable downtime is preferable to unexpected outages, allowing for controlled stress-testing and upgrades that reduce the risk of catastrophic failure during live trading. Regarding the POL suspension, analysts emphasize it is a security-first practice to prevent potential double-spend attacks or reconciliation errors during a chain transition, aligning with protocols used by global exchanges like Coinbase and Binance during similar events.
Upbit has a history of executing such maintenance with minimal disruption. The exchange assures users that funds remain secure in custodial wallets during both events. For the Polygon hard fork, users holding POL on Upbit need not take action, while those using self-custody wallets should confirm their provider supports the post-fork chain.
