Announcement on the Discontinuation of the Cobo Wallet App and Asset Withdrawal Arrangements

Dear Cobo Wallet users,

Due to our strategic business adjustment, Cobo Wallet App will cease service on December 1, 2026 (UTC+8). Cobo’s other businesses are not affected and will continue to operate as normal.

To safeguard your assets, please make sure to withdraw all assets from your account before 23:59 on November 30, 2026 (UTC+8).

1. Cobo Wallet App Wind-down Timeline

From December 1, 2026, 00:00:00 (UTC+8), the App will cease service. Please make sure all assets have been withdrawn before this time.

⚠ Action required, please complete as soon as possible:

• Update your receiving addresses: If you have set a Cobo Wallet address as a receiving address on any exchange, mining pool or other platform, please replace or remove it, to avoid assets being sent there by mistake.

2. Handling of Assets Not Withdrawn by the Deadline

2.1 Fee Structure

If any assets remain in your account after the App ceases service, Cobo will charge a monthly account management fee. The fee will be calculated at 2% of the remaining assets in your account, subject to a minimum monthly fee equivalent to USD 100. If you fail to withdraw your assets before the App ceases service, you will be deemed to have agreed to this fee arrangement.

2.2 How the Fee Is Charged

• Fee Collection Time: The fee for the preceding calendar month will be charged on the 1st of each month at 00:00 (UTC+8). The first fee will be charged on January 1, 2027, for the account management fee for December 2026.

• Deduction in tokens: The fee will be calculated based on the remaining quantity of each token in the account at the time of collection. The fee will be deducted directly from your account in the respective tokens at a rate of 2%, with no currency conversion.

• Minimum fee: If the total fee calculated at 2% for the month is less than the equivalent of USD 100, a fee equivalent to USD 100 will be charged instead. The fee will be deducted from each token in proportion to its share of the total value of the assets in the account. USD values will be calculated based on CoinMarketCap prices at the time of collection.

• Insufficient balance: If the total value of your remaining assets is less than the equivalent of USD 100, all remaining assets will be deducted in a single transaction.

• Fees will continue to be charged until all remaining assets have been withdrawn or fully deducted.

2.3 Examples

• Account balance of 1 BTC and 10 ETH: 0.02 BTC and 0.2 ETH are deducted for the month (total value above 100 USD).

• Account balance of 1,000 USDT only: 2% would be 20 USDT, which is below the minimum fee, so 100 USDT is deducted for the month.

• Account balance of 60 USDT only: The balance is below the minimum fee, so all 60 USDT is deducted for the month.

3. Security Reminder

• Cobo staff will never ask for your personal information, password, seed phrase or private key for any reason.

• Cobo does not offer any “paid expedited withdrawal” or “asset transfer on your behalf” services.

• Please only trust our official website (www.cobo.com) and official email address ([email protected]), and beware of scams by anyone impersonating customer support.

Thank you for your trust and support.
