In a recent service update, OKX announced the temporary suspension of deposit functions for several major blockchain networks to facilitate essential system upgrades. The maintenance affects key Layer-2 and EVM-compatible chains including Arbitrum (ARB), Optimism (OP), Linea, Manta, Metis, Base, StarkNet, MXC, Lisk (LSK), and zkSync Era. This planned upgrade reflects OKX’s ongoing commitment to enhancing platform stability, security, and user experience across its growing Web3 ecosystem.
The maintenance window began on June 17, 2024, at 14:30 HKT, with deposits paused across all supported wallets for the listed networks. According to official communications, normal deposit operations are expected to resume by June 21, 2024, at 18:00 HKT. Users are advised to monitor the OKX platform or official announcements for real-time updates in case of schedule adjustments.
Why Network Upgrades Matter for Crypto Wallets
Blockchain wallet services like OKX must periodically perform backend upgrades to stay aligned with evolving network protocols, security standards, and performance demands. These maintenance activities ensure that:
- Transaction processing remains fast and reliable
- Smart contract interactions are secure and accurate
- Wallet integrations support the latest network features
- User funds remain protected during high-traffic or vulnerable periods
Layer-2 solutions such as Arbitrum, zkSync Era, and Optimism are especially dynamic, frequently rolling out protocol improvements that require wallet providers to update their integration layers. Similarly, emerging ecosystems like Manta Network and Linea often introduce new consensus mechanisms or privacy features that necessitate technical alignment from third-party platforms.

Affected Networks and Their Roles in the Web3 Landscape
Here's a closer look at the impacted blockchains and their significance in today’s decentralized infrastructure:
Arbitrum (ARB)
As one of the most widely adopted Layer-2 scaling solutions for Ethereum, Arbitrum enables low-cost, high-speed transactions while maintaining Ethereum’s security model. It hosts hundreds of DeFi protocols and NFT marketplaces.
Optimism (OP)
Optimism leverages optimistic rollup technology to scale Ethereum efficiently. Its ecosystem includes major projects like Synthetix and Uniswap, making it a critical component of the DeFi stack.
zkSync Era
Built on zero-knowledge rollup (zk-rollup) technology, zkSync Era offers enhanced privacy and scalability. Its growing developer community is pushing the boundaries of ZK-based smart contracts.
Base
Developed by Coinbase, Base is an open-source Layer-2 network designed to onboard millions of new users into Web3 through low fees and seamless onboarding experiences.
Linea
Consensys’ Linea is an EVM-equivalent zk-rollup that allows developers to deploy existing Ethereum dApps without modification—making it highly attractive for rapid deployment.
Manta Network
Focused on privacy-preserving transactions, Manta uses zk-SNARKs to enable confidential asset transfers across multiple chains, appealing to users seeking financial privacy.
Metis
Metis enhances Ethereum scalability with its own DAO-focused Layer-2 framework, supporting fast finality and decentralized governance structures.
StarkNet
Utilizing STARK proofs, StarkNet delivers high throughput and censorship-resistant computation, serving as a foundational layer for next-gen dApps.
MXC & Lisk (LSK)
While MXC focuses on IoT data exchange via blockchain, Lisk provides a modular blockchain SDK for JavaScript developers, lowering entry barriers for new builders.
These diverse networks represent the cutting edge of blockchain innovation—each requiring precise integration and continuous maintenance from wallet providers like OKX.
What Users Should Know During the Downtime
While only deposits are suspended during this period, other wallet functionalities—including withdrawals, swaps, staking, and trading—remain fully operational. Users should take note of the following:
- ✅ Withdrawals are unaffected – You can still send assets out of your OKX wallet.
- ❌ Deposits will fail – Sending tokens to OKX via any of the listed networks during maintenance may result in lost funds or delayed crediting.
- 🔁 Auto-resumption expected – Once maintenance concludes, deposit functions will automatically reactivate without user intervention.
- 📢 Stay informed – Follow OKX official channels for confirmation when services return to normal.
To avoid transaction errors or potential loss of funds, users are strongly advised not to initiate deposits to these networks until full functionality is restored.
Frequently Asked Questions (FAQ)
Q: Which specific tokens are affected by the deposit pause?
A: The suspension applies to native tokens and ERC-20-style assets on the following networks: Arbitrum (ARB), Optimism (OP), Linea, Manta, Metis, Base, StarkNet, MXC, Lisk (LSK), and zkSync Era.
Q: Can I still trade or withdraw my assets during maintenance?
A: Yes. Trading, withdrawals, staking, and other wallet features remain fully available. Only incoming deposits to the specified networks are paused.
Q: What happens if I accidentally send funds during the downtime?
A: While transactions may be broadcasted successfully on-chain, they will not be credited to your OKX account until deposit functionality resumes. In most cases, funds will be processed once the system is back online—but sending assets during downtime is not recommended.
Q: How often does OKX perform such upgrades?
A: Regular maintenance is conducted as needed to ensure optimal performance and compatibility with fast-evolving blockchain ecosystems. Major upgrades typically occur several times per year.
Q: Will there be future notifications for similar events?
A: Yes. OKX proactively announces scheduled maintenance through its official website, app alerts, email notifications, and social media channels.
Q: Is my money safe during this time?
A: Absolutely. Your assets are secure at all times. The deposit pause is purely a preventive measure to ensure accurate transaction processing after system updates.
Staying Ahead in a Fast-Moving Ecosystem
As blockchain technology evolves at breakneck speed, wallet providers must continuously adapt. OKX’s proactive approach to system maintenance ensures long-term reliability for users engaging with multiple chains—from mainstream Layer-2 solutions to niche privacy-focused networks.
Such upgrades also highlight the importance of choosing a wallet platform that prioritizes technical robustness, cross-chain compatibility, and transparent communication—qualities that define top-tier Web3 infrastructure providers.

For users holding assets on any of the affected networks, patience during scheduled maintenance contributes to a safer and more efficient experience post-upgrade. Always verify service status before initiating transactions to avoid unnecessary delays.
Final Notes on Security and Best Practices
Even outside scheduled maintenance windows, users should follow best practices:
- Double-check network selection before every deposit
- Use test transactions with small amounts when depositing to new chains
- Enable two-factor authentication (2FA) on your wallet account
- Regularly review transaction history for anomalies
Blockchain ecosystems thrive when both platforms and users act responsibly. By pausing deposits proactively, OKX demonstrates its dedication to operational excellence and user protection in an increasingly complex digital asset landscape.
