BNB Smart Chain Schedules Fermi Hard Fork Upgrade

The BSC mainnet Fermi hard fork is scheduled for January 14, 2026, requiring all validators to upgrade to v1.6.4 or v1.6.5. Binance will suspend BEP20 deposits/withdrawals during the upgrade, primarily affecting BNB and ecosystem tokens.

The Fermi hard fork implicates significant changes on the BNB Smart Chain (BSC), scheduled for January 14, 2026. Developers have mandated that all validators and builders upgrade to versions v1.6.4 or v1.6.5. The upgrade is part of a community-run decentralized network originally launched by Binance. On January 14, 2026, around 02:30 AM UTC, BNB Chain planners will execute these adjustments.

Binance, as a key player, will suspend deposits and withdrawals to minimize disruptions. The scheduled Fermi fork primarily affects BNB Smart Chain’s BEP20 tokens, including key ecosystem assets like BNB. Binance plans to suspend deposits/withdrawals at the event due to this upgrade. This suspension process ensures synchronization between networks. Financial adjustments might occur as different assets experience temporary pause impacts. However, no effects on external cryptocurrencies, such as ETH or BTC, are currently identified.

No funding increments or grants related to the fork have been publicized. The fork’s execution might alter existing financial landscapes by affecting BNB’s liquidity pools or staking procedures. Developers preparing for the fork include alterations which may optimize network functionality, potentially by reducing block times or revising voting parameters. With historical precedents lacking, stakeholders remain vigilant for operational insights.
