Bithumb, a leading South Korean cryptocurrency exchange, will temporarily suspend deposits and withdrawals for twelve digital assets on the Arbitrum network starting January 8, 2025, at 09:00 UTC. This suspension supports a critical upgrade to the Arbitrum scaling solution. Affected assets include ARB, ETH, and GMX, among others. Trading on Bithumb's internal order books will remain unaffected during this period. The suspension is a routine measure to ensure a smooth transition during the network upgrade, which aims to enhance Arbitrum's performance and security. Users are advised to complete necessary transactions before the suspension and monitor Bithumb's announcements for updates on service resumption. Such technical suspensions are typically brief and are not expected to cause significant market volatility.
