BNB Smart Chain (BEP20) Network Upgrade and Hard Fork Support Announcement

·

BNB Smart Chain (BEP20) is set to undergo a significant network upgrade and hard fork, marking another milestone in its evolution as a leading blockchain platform for decentralized applications and token transactions. As one of the most widely used networks for BEP-20 tokens, any changes to its infrastructure require careful coordination—especially from major exchanges like OKX. This article provides a comprehensive overview of the upcoming upgrade, how it affects users, and what steps platforms like OKX are taking to ensure a smooth transition.

Understanding the BNB Smart Chain Upgrade

The BNB Smart Chain (BEP20) network upgrade is scheduled to take place at block height 22,107,423, which was estimated to occur around October 12, 2022, at 16:00 HKT. This upgrade involves a hard fork—a fundamental change in the blockchain’s protocol that results in a permanent divergence from the previous version of the blockchain.

Hard forks are typically implemented to introduce new features, improve security, or fix critical vulnerabilities. In this case, the upgrade aims to enhance network performance, optimize consensus mechanisms, and support future scalability improvements across the BNB ecosystem.

Why Network Upgrades Matter

Blockchain networks must evolve to meet growing demands for speed, security, and decentralization. Without periodic upgrades, networks risk becoming outdated, inefficient, or vulnerable to attacks. The BEP20 network upgrade ensures continued reliability for millions of users who rely on it for token transfers, DeFi interactions, NFT transactions, and more.

For exchanges like OKX, supporting such upgrades is essential to maintaining asset integrity and user trust. Any disruption during the process could lead to lost funds or transaction failures—making proactive planning crucial.

OKX’s Response to the BEP20 Hard Fork

To ensure the safety of user assets and the stability of its services, OKX announced the temporary suspension of BEP-20 token deposits and withdrawals starting at 15:00 HKT on October 12, 2022—one hour before the expected fork time.

This precautionary measure allows the exchange to:

Once the network stabilizes after the hard fork, OKX will resume deposit and withdrawal services. Users will be notified via official announcements when operations return to normal.

Key Details You Need to Know

It's important to note that while trading remains active, transferring BEP-20 tokens to or from external wallets during the maintenance window may result in irreversible loss of funds. Users are strongly advised to avoid sending tokens until full service resumption.
