Binance will suspend deposits and withdrawals on the Base network beginning at 17:00 UTC on September 30, 2026. This service pause is scheduled to facilitate the Base network's Cobalt upgrade and hard fork, which is expected to occur around 18:00 UTC.
Why it matters
The suspension ensures operational stability during the Cobalt hard fork, a technical event required to implement structural changes to the Base network protocol. While these services will be unavailable, trading activities for Base-based tokens will continue to function on the exchange.
The Cobalt upgrade precedes a future Denim update scheduled for October 2026, which aims to achieve a cadence of 200ms for native blocks. These upgrades represent structural adjustments to the Base network's underlying consensus and block-production architecture.
The players
Binance
A global cryptocurrency exchange providing liquidity and custodial services for a broad range of digital assets and blockchain networks.
Base network
An Ethereum Layer 2 blockchain incubated by Coinbase designed to provide a secure and low-cost environment for decentralized applications.
Coinbase
A publicly traded cryptocurrency exchange and infrastructure provider that serves as the primary incubator for the Base network.
The details
The Cobalt upgrade involves a hard fork, a permanent divergence in the blockchain that requires network participants to upgrade their software to remain compatible with the new protocol rules. Binance will manage all technical backend adjustments required during this transition. Once the network reaches stability following the hard fork, the exchange will automatically restore deposit and withdrawal services for users.
Timeline
September 30, 2026, 17:00 UTC: Binance suspends deposits and withdrawals on the Base network.
September 30, 2026, 18:00 UTC: The Base network Cobalt upgrade and hard fork are scheduled to take place.
October 2026: The Base network plans to implement the Denim upgrade.
The Tech Race
The Cobalt upgrade follows the established development milestones outlined in the Base network roadmap. This hard fork marks a specific execution phase in the ongoing multi-stage development and performance-scaling plan set for the Base ecosystem.
Users will be unable to transfer assets into or out of the Base network on Binance during the maintenance window on September 30. Trading functions remain active, but deposits and withdrawals will only resume once the platform confirms the network is stable after the upgrade.
The takeaway
Maintaining service during network hard forks requires exchanges to carefully time maintenance windows to align with protocol upgrades. Watch for the restoration of Binance deposit services to confirm the Cobalt hard fork has achieved successful network consensus.
What happens next
Users should monitor the Base network status for the completion of the Cobalt upgrade and the subsequent Denim upgrade, which is planned for release in October 2026.
