To support the upcoming Fusaka network upgrade, we will be conducting scheduled maintenance on deposits and withdrawals for Ethereum and several Layer-2 networks.

Maintenance Schedule (UTC+8)

The suspension schedule is outlined below, broken down by network.

Base & Optimism Hard Fork

The Base and Optimism networks will undergo their upgrades prior to the main Ethereum event.

• Deposit & Withdrawal Suspension Time: 2025/12/02 18:00:00 (UTC+8)

Ethereum Fusaka Hard Fork (Mainnet & All Layer 2s)

This is the main network upgrade for Ethereum, which will also require suspension across all connected L2 networks: Arbitrum, Optimism, Base, Blast, Scroll, ZKSync, and Metis. Polygon transactions may also be affected, depending on their final timeline.

• Deposit & Withdrawal Suspension Time: 2025/12/04 05:35:00 (UTC+8)

• Expected Re-enable Time: 2025/12/04 06:05:00 (UTC+8)

Note: If abnormalities occur, the reopening time will be adjusted based on on-chain conditions.

Tokens Impacted

• Ethereum Mainnet: ETH, all ERC-20 tokens

• Arbitrum One: ETH on Arbitrum, ~8 tokens

• Optimism: OP, WLD

• Base: ETH on Base, 10+ on-chain tokens

During the maintenance window, deposits and withdrawals for these networks will be paused. All other networks remain fully available, and trading will not be affected.

We will resume services as soon as the networks complete their upgrade and are confirmed to be stable.
