Pionex Will Delist Selected Spot Trading Pairs

Dear Users,

Pionex will periodically review each digital asset we list to ensure that it keeps the high standard level we expect. When a coin or token no longer meets this standard or the industry changes, we conduct a more in-depth review and potentially delist it.

When we conduct these reviews, we consider a variety of factors. Here are some that drive whether we decide to delist a token or coin:

• The commitment of the team to the project
• Level and quality of development activity
• Trading volume and liquidity
• Stability and safety of network from attacks
• Network / smart contract stability
• Evidence of unethical/fraudulent conduct or negligence

According to the above factors, we will delist and cease trading on the following trading pair at 03:00 on June 1st,2026(UTC) :

• USDR/USDC, USDR/USDT, USDQ/USDC, USDQ/USDT, EURR/USDT, EURQ/USDT, BTC/USDQ, BTC/USDR

To provide you with a better trading experience, Pionex has been maintenance on the selected Spot trading pair(s) at 10:40 on May 29, 2026 (UTC), the estimated maintenance completion time is tentative.

Please note

• During the maintenance period, manual trading for the corresponding trading pairs, as well as the opening and closing of bot orders, will be suspended.

• After trading is suspended, the corresponding bot orders and manual orders for the trading pairs will be canceled.

• USDR and USDQ holdings will be returned with the stablecoin USDT at a 1:1 ratio after delisting, while EURR and EURQ holdings will be returned with the stablecoin USDT at a ratio of 1:1.1634 to eligible holders.

Risk warning:

Trading in the crypto market carries a substantial risk and the possibility of making both significant profits and losses. Please trade cautiously. Though Pionex will make its best efforts to choose high-quality assets, Pionex could not assure any profit and will not be responsible for your trading loss.

Thanks for your support!
