South Korean cryptocurrency exchange Bithumb has initiated a temporary suspension of deposit and withdrawal services for Toncoin (TON), the native asset of The Open Network. The operational halt is scheduled to commence precisely at 13:00 UTC on June 2, 2025, serving as a prerequisite for an imminent mainnet upgrade. According to official communications from the exchange, this suspension represents a standard operational protocol designed to maintain data integrity during critical blockchain transitions. Mainnet upgrades frequently necessitate modifications to the underlying protocol, compelling exchanges to freeze token movements to prevent transaction errors and ensure ledger consistency throughout the technical migration. While Bithumb has not disclosed the specific duration of this service interruption, historical precedents indicate that such halts persist until the upgrade is successfully deployed and network stability is verified by technical teams.

Data compiled by Woofun AI shows that the exchange has explicitly advised all users to finalize any pending TON transactions prior to the 13:00 UTC cutoff to mitigate potential delays. For active market participants, this suspension renders TON deposits and withdrawals inaccessible for an undetermined timeframe, creating immediate liquidity constraints for external transfers. Although the freeze targets off-chain movements, trading pairs involving TON on the spot market may continue to function normally, contingent upon the exchange's internal risk management policies during the maintenance window. This distinction allows traders to manage existing positions without the ability to move assets in or out of the platform, effectively isolating the exchange's internal ledger from the external network during the upgrade phase.

Users holding TON balances on the platform must recognize that transferring tokens to external wallets or depositing new assets from third-party sources will be impossible until services are fully restored. This restriction poses significant challenges for arbitrage strategies and time-sensitive asset reallocations that rely on rapid cross-platform movement. The Open Network, originally conceptualized by Telegram, has been executing a series of iterative upgrades focused on enhancing scalability, transaction throughput, and smart contract capabilities. These technical improvements are driving increased adoption in decentralized applications and payment infrastructures, yet they inherently introduce short-term friction for exchange users reliant on continuous deposit and withdrawal functionality.

Woofun AI notes that Bithumb's decision to suspend TON services is a routine technical measure aligned with industry best practices for supporting complex mainnet upgrades. The exact timeline for service resumption remains unannounced, but the halt is projected to last only as long as necessary to guarantee the security and stability of the upgraded network. Regular network maintenance serves as a barometer for active development, signaling ongoing efforts to refine the blockchain's core architecture despite the temporary inconvenience to retail and institutional holders. Traders and asset managers are urged to adjust their operational plans accordingly and closely monitor official channels from Bithumb for real-time updates regarding the restoration of full deposit and withdrawal capabilities.
