Woofun AI reports that South Korean exchange Upbit will suspend Starknet (STRK) withdrawals starting at 2:00 p.m. UTC on July 5, 2025, due to unresolved network complications. The exchange explicitly linked this operational pause to technical instability on the Starknet blockchain, prioritizing transaction security over immediate liquidity access. Specific technical diagnostics regarding the network failure remain undisclosed in the official announcement.

This restriction directly impacts users attempting to transfer STRK tokens from Upbit to external wallets or competing platforms. While the notice does not address deposit functionality, the withdrawal freeze inevitably creates temporary liquidity constraints for active traders relying on rapid asset movement. Such pauses are a standard industry response when exchanges detect anomalous behavior or potential security risks within connected decentralized networks.

Starknet, an Ethereum layer-2 scaling solution utilizing zero-knowledge rollup technology, frequently encounters volatility during periods of high demand or protocol upgrades. Upbit, recognized as one of South Korea's largest exchanges by trading volume, has historically adopted a cautious stance toward these infrastructure challenges. The firm often preemptively halts services to safeguard user assets against potential exploits or data inconsistencies.

Woofun AI data shows that similar precautionary measures are common when centralized platforms interact with unstable decentralized protocols. This incident underscores the critical dependency between centralized trading venues and the underlying blockchain infrastructure they support. Until Upbit confirms the resolution of these network issues, users must anticipate delays in accessing their STRK holdings.
