Two major South Korean cryptocurrency exchanges, Upbit and Bithumb, have announced temporary suspensions of deposit and withdrawal services for BERA and SEI tokens, respectively. Both suspensions are a direct result of planned network upgrades on the Berachain and Sei blockchains, highlighting standard maintenance practices in the industry.
Upbit will halt BERA deposits and withdrawals on August 5 at 11:00 a.m. UTC. The exchange cited Berachain’s ongoing development activity, which includes upgrades to improve scalability and user experience. BERA, the native token of the layer-1 proof-of-liquidity network, will continue to be tradable on Upbit during the maintenance window, with only transfer functions paused.
Bithumb, on the other hand, will suspend SEI deposits and withdrawals a day earlier, on August 4 at 9:00 a.m. UTC. The reason is a Sei network upgrade aimed at boosting performance and security for the trading-focused layer-1 blockchain. As with Upbit, spot trading of SEI will remain unaffected, though users will be unable to move tokens on or off the exchange until the upgrade is verified and services are restored.
Both exchanges emphasized that the suspensions are precautionary measures to protect user funds and ensure transaction integrity during the network transitions. Neither Upbit nor Bithumb provided a specific end time for the halts, but such maintenance typically lasts a few hours. Affected holders are advised to complete any pending transfers before the cutoff times and monitor official channels for resumption notices.
