OKX will temporarily suspend USDC deposits and withdrawals on the Solana network on July 14 while it completes scheduled wallet maintenance. Summary OKX will pause Solana USDC deposits and withdrawals while keeping related trading services fully operational. The suspension begins July 14 at 14:30 UTC+8 and resumes after maintenance without separate announcement. Solana remains a major USDC settlement network despite this short exchange-level maintenance window for users. The pause will begin at 14:30 UTC+8, equal to 06:30 UTC and 09:30 East Africa Time. OKX published the notice on July 13 and did not provide a fixed completion time. The exchange said it will restore the two services after the work ends. The change applies only to deposits and withdrawals of USDC through Solana. OKX said users who already hold the token in their accounts do not need to take action. Trading for related assets will continue during the maintenance period. Other supported USDC networks were not included in the notice, so the announcement does not describe a platform-wide USDC suspension. 由于钱包维护，我们将于7月14日14:30 (UTC+8) 暂停 USDC 在 Solana 网络的充提服务，待维护完成后恢复。相关代币的交易不受影响，请勿在钱包维护期间进行 USDC 的充提操作，以免造成资金损失，感谢您的理解与支持~— OKX中文 (@okxchinese) July 13, 2026 OKX also advised traders to consider risks in margin and derivatives markets and add margin early where needed. That guidance matters for users who move USDC through Solana to fund positions. The notice does not promise that deposit networks will remain available in every region, so customers should rely on the options shown in their accounts. Users should avoid transfers during the pause OKX asked customers not to send or withdraw Solana-based USDC after the maintenance window opens. The exchange warned that transfers made during the pause could create a risk of lost funds. Users should check the selected network before confirming any transaction, because USDC exists on several blockchains and each network uses a different deposit route. Users should allow time for blockchain confirmations before the cutoff, since a transfer initiated earlier may arrive after the suspension begins. The company described the work only as “wallet maintenance.” It did not report a hack, a Solana network outage, or a problem with USDC. OKX also said “trading will not be affected,” although that statement covers exchange trading rather than external transfers. The exchange did not explain whether pending transactions submitted before the cutoff could face delays. Solana remains a major USDC settlement network USDC on Solana is a native version of Circle’s dollar-backed stablecoin rather than a wrapped token issued by another bridge provider. Circle lists Solana among the networks where it directly issues USDC. Its cross-chain tools can also burn native USDC on one supported network and mint the same amount on another, without using wrapped copies or outside liquidity pools. As crypto.news reported earlier in 2026, Circle minted more than $10.5 billion in USDC on Solana within roughly one month. The same coverage cited about $650 billion in Solana stablecoin settlement volume during February. Those figures show the network’s large role in dollar-denominated transfers, but they do not indicate that OKX’s maintenance pause resulted from higher usage. Exchange notice does not signal a Solana shutdown Solana has also attracted more payment and financial infrastructure. As previously reported, the Solana Foundation launched an institutional developer platform with Mastercard, Western Union and Worldpay as early users. The tools cover stablecoin issuance, payments and trading services. That expansion increases the need for exchanges and custodians to maintain reliable wallet systems as transaction routes grow. The OKX notice remains an exchange-level service update, not a suspension of USDC on the Solana blockchain. Users can still trade supported assets inside OKX, but they should avoid Solana USDC deposits and withdrawals until the exchange restores access. OKX said it may resume the services without another announcement, making the platform’s deposit page and status tools the main places to check before sending funds.
