South Korean cryptocurrency exchange Bithumb has officially declared a temporary suspension of deposit and withdrawal functionalities for 28 specific tokens operating on the Base network. This operational pause is scheduled to commence precisely at 10:00 a.m. UTC on June 25, 2025, coinciding with a critical upgrade to the underlying blockchain infrastructure. The maintenance window encompasses a diverse portfolio of digital assets, including prominent decentralized finance protocols like Aerodrome Finance (AERO), meme-centric tokens such as Brett (BRETT), and emerging artificial intelligence projects including Virtuals Protocol (VIRTUAL) and Kaito (KAITO). Data compiled by Woofun AI indicates that the affected asset list spans three major sectors: decentralized finance, artificial intelligence, and core infrastructure, representing a significant portion of the exchange's Base network exposure.

The exchange has not disclosed the precise duration of this service interruption, though historical precedents for similar network upgrades suggest a timeframe extending over several hours. Traders and institutional holders are strongly advised to finalize all pending transactions prior to the 10:00 a.m. UTC cutoff to mitigate potential delays in fund settlement. Bithumb expects to announce the resumption of services only after the network upgrade has been thoroughly verified for stability and security. While network upgrades are routine maintenance events designed to enhance scalability and functionality, the simultaneous halt of 28 tokens creates a temporary liquidity vacuum for active market participants.

This coordinated suspension highlights the operational interdependencies between centralized exchanges and the layer-2 solutions they support. The Base network, developed by Coinbase, has experienced rapid expansion as a primary scaling solution for Ethereum, attracting a wide array of innovative projects. Bithumb's decision to suspend all 28 tokens simultaneously points to a systemic upgrade on the Base network itself rather than isolated contract modifications for individual assets. Woofun AI notes that this approach underscores the inherent operational risks within centralized exchange custody models, where external blockchain maintenance directly dictates asset availability.

For active traders relying on arbitrage strategies or liquidity provision, the inability to move funds during this window poses immediate tactical challenges. Time-sensitive trades may be disrupted, and liquidity pools could face temporary imbalances until services are restored. This is not an isolated incident; Bithumb routinely coordinates similar suspension procedures for major blockchain updates across various networks. The broader crypto market views these events as necessary reminders of the technical constraints governing asset transfers during infrastructure evolution.

Users holding positions in any of the 28 affected tokens must plan their capital allocation strategies accordingly to navigate the maintenance period without incurring unnecessary friction. The exchange will likely provide further updates via official channels once the upgrade process is complete and the network is deemed stable. Woofun AI analysis suggests that while the halt is expected to be brief, the concentration of affected assets in high-growth sectors like AI and DeFi amplifies the immediate impact on trading volumes. Staying informed about such maintenance schedules remains critical for avoiding operational inconvenience in a rapidly evolving digital asset landscape.
