[Important Notice] Upgrade of Asset Decentralization Features

Dear CoinQ Users,

Thank you for your continued trust and support.

To further enhance asset security and user experience, we will soon complete a comprehensive upgrade to our asset decentralization features. After the upgrade, you will have the option to keep your assets in your own wallet while trading on CoinQ, achieving true self‑custody and giving you full control over the security of your funds.

I. Upgrade Highlights
The core of this upgrade is the introduction of wallet‑based login functionality, which includes:

1. Multi‑wallet connectivity support: Mainstream wallets (such as MetaMask, Trust Wallet, OKX Wallet, etc.) can be connected for login, allowing you to seamlessly access the platform with your preferred wallet.
2. Account binding: After logging in with a wallet, you may optionally bind your mobile number and email address, combining the decentralized experience with convenient account management.
3. Smart deposits and withdrawals:
   • For on‑chain deposits, if the deposit chain matches the chain of the wallet you have connected, you can directly invoke your wallet to complete the transfer without manually copying the address.
   • For withdrawals, if the withdrawal chain matches the chain of your connected wallet, the withdrawal address will default to your connected wallet address for quicker operations.

II. Core Advantages
After this upgrade, you can choose to store your assets in your own wallet rather than relying entirely on the platform’s unified custody. This means:

• Greater autonomy: You are in full control of your private keys and digital assets, and the safety of your assets rests with you.
• More convenient asset management: You have complete control over your own assets and can manage them without going through any third party.

III. Impact of the Upgrade
During the upgrade process, users will experience the following impacts, and we appreciate your understanding:

• To ensure the safety of the upgrade, deposit and withdrawal services will be temporarily suspended.
• After the upgrade is completed, your deposit address will be changed, and old deposit addresses will no longer be valid.

Deposit and withdrawal suspension time: July 18, 2026, 9:00 (UTC+8)
The resumption time will be announced separately – please stay tuned to our official announcements.

IV. Important Reminders

1. Deposit address change: After the upgrade, your deposit address will be updated, and the old address will cease to function. Please retrieve and use the new deposit address promptly after services resume.
2. Update to the latest APP version: After the upgrade, you will need to update your APP to the latest version to enjoy the full asset decentralization features.
3. Arrange deposits and withdrawals in advance: Since deposit and withdrawal services will be suspended during the upgrade, please make sure to arrange your transfers ahead of time to avoid any potential losses due to market fluctuations affecting your positions.

If you have any questions during the upgrade, please feel free to contact us through our official customer support channels.
Thank you for your understanding and support!
