Cryptocurrency exchanges must continuously adapt to the evolving blockchain landscape to ensure secure, efficient, and future-ready services. At the forefront of this innovation is OKX, a leading digital asset platform committed to supporting major network upgrades, token migrations, and new blockchain integrations. This article explores recent deposit and withdrawal announcements from OKX, covering network upgrades, hard forks, token delistings, and chain enhancements — all critical for users managing their digital assets effectively.
Whether you're a long-term investor or an active trader, staying informed about these changes helps prevent transaction failures, ensures fund safety, and maximizes access to emerging blockchain ecosystems.
Recent Network Support and Upgrades
OKX consistently expands its infrastructure to support high-potential blockchain networks and upgrades. These updates often involve mainnet upgrades, new token listings on specific chains, or integration of cross-chain protocols.
Unichain Network Integration
On June 5, 2025, OKX announced full support for Unichain, a modular Layer 2 network designed to enhance scalability and interoperability across Ethereum’s ecosystem. This integration enables users to deposit and withdraw assets seamlessly via the Unichain network, positioning OKX as an early adopter of next-generation Ethereum scaling solutions.

Siacoin (SC) Network Upgrade & Hard Fork
Scheduled for June 4, 2025, OKX prepared for the Siacoin (SC) network upgrade, which included a hard fork. During such events, the blockchain splits into two versions — old and new. To protect user funds, OKX temporarily suspended SC deposits and withdrawals during the transition. Once network stability was confirmed, services resumed with full compatibility with the upgraded chain.
USDC on Aptos and Sui Chains
Stablecoin accessibility continues to grow across emerging blockchains. In May 2025, OKX began supporting USDC on the Aptos chain, followed by integration on the Sui chain earlier in February. These moves reflect rising demand for fast, low-cost stablecoin transactions in high-performance ecosystems.
Aptos and Sui, both built on the Move programming language, offer enhanced security and throughput — ideal for DeFi applications and everyday payments.
Ethereum Mainnet Upgrade
The Ethereum (ETH) mainnet upgrade on May 7, 2025, marked another milestone in the network’s continuous evolution. Known for its robust developer community and dominant DeFi presence, Ethereum periodically rolls out protocol improvements to boost efficiency and reduce congestion. OKX supported this upgrade by pausing ETH-related transactions briefly before resuming full operations post-consensus.
Token Migrations and Chain Transitions
Some projects undergo structural changes requiring users to migrate tokens or shift asset holdings between chains. OKX facilitates these transitions smoothly.
PHA and RIO Crypto Migrations
OKX supported both PHA and RIO token migrations in January and October 2024 respectively. These migrations typically occur when a project moves from one blockchain to another — often to leverage better performance or governance features. Users were advised to complete migrations before deadlines to avoid loss of access.
TON Wallet Maintenance
On January 1, 2025, OKX conducted scheduled wallet maintenance for the TON (The Open Network) blockchain. While deposits and withdrawals were paused temporarily, this proactive measure ensured long-term reliability and security for TON asset holders.
Discontinuation of Legacy Network Support
As blockchain ecosystems mature, outdated or underutilized networks are phased out in favor of more efficient alternatives.
Discontinuation of DYDX on ERC-20
In April 2025, OKX discontinued support for DYDX tokens on the ERC-20 network. This decision aligned with dYdX’s broader strategy to operate independently via its own appchain, reducing reliance on Ethereum for core trading functions. Users were required to move their DYDX holdings to the native dYdX chain before the cutoff date.
Cessation of USDC on Optimism (Bridged)
Similarly, in August 2024, OKX ceased USDC deposits and withdrawals on the Optimism (Bridged) network. This change encouraged users to adopt native USDC on Optimism’s Layer 2 network, which offers faster settlement and improved capital efficiency.
Multi-Network Mainnet Upgrades
OKX also supports coordinated upgrades across multiple blockchains simultaneously.
On January 8, 2025, OKX announced support for mainnet upgrades on OP (Optimism), MANTA, BASE, MODE, WORLD, and LISK networks. Such synchronized efforts highlight the growing interdependence of Layer 1 and Layer 2 platforms in delivering scalable Web3 experiences.
Other notable upgrades included:
- Kaia (KLAY) – August 28, 2024
- FLOW – August 28, 2024
- METIS – August 19, 2024
Each upgrade aimed at improving consensus mechanisms, reducing fees, or enhancing smart contract capabilities.

Frequently Asked Questions (FAQ)
Q: Why does OKX suspend deposits or withdrawals during network upgrades?
A: Temporary suspensions prevent lost or misrouted funds during protocol transitions like hard forks or mainnet upgrades. They ensure all transactions comply with the latest network rules.
Q: What should I do if my token is being migrated?
A: Follow official migration instructions before the deadline. If you hold affected tokens on OKX, the platform usually handles migration automatically. For self-custody wallets, act promptly to avoid inaccessibility.
Q: Can I still trade a token if it's discontinued on one network?
A: Yes — unless the asset is fully delisted. For example, DYDX remains tradable on OKX but only through its native chain, not ERC-20.
Q: How will I know when services resume after maintenance?
A: OKX publishes real-time updates via its Help Center and official social channels. You can also enable platform notifications for immediate alerts.
Q: Are my funds safe during network upgrades?
A: Absolutely. OKX prioritizes asset security by coordinating closely with blockchain teams and conducting thorough testing before resuming services.
Q: Does supporting a new chain mean lower fees for users?
A: Often yes. Newer chains like Aptos and Sui are optimized for low-cost transactions, especially for stablecoins like USDC and USDT.
