South Korean Exchange Halts Deposits for Six Sui-Based Assets

Upbit, one of South Korea's largest cryptocurrency exchanges by trading volume, has temporarily suspended deposits and withdrawals for six Sui-based assets due to a halt in block production on the Sui network. The affected assets are DeepBook (DEEP), Haedal Protocol (HAEDAL), LumiWave (LWA), Momentum (MMT), Sui (SUI), and Walrus (WAL).

The exchange announced the suspension on March 27, citing the need to protect user funds during the network disruption. Although the Sui team has resolved the underlying bug causing the halt, Upbit is taking a cautious approach and conducting its own internal review.
