At Phemex, we periodically review each digital asset we list to ensure that it continues to meet the high level of standard 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. We believe this best protects all our users.

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

• Commitment of team to project
• Level and quality of development activity
• Trading volume and liquidity
• Stability and safety of network from attacks
• Network / smart contract stability
• Level of public communication
• Responsiveness to our periodic due diligence requests
• Evidence of unethical/fraudulent conduct or negligence.
• Contribution to a healthy and sustainable crypto ecosystem

Based on our most recent reviews, we have decided to delist and cease trading on the following spot trading pair at 8:00 UTC on May 13, 2022.

• SOS (OpenDAO)

Please note:

• The exact trading pair being delisted is SOS/USDT.
• All trade orders will be automatically removed after trading ceases in each respective trading pair.
• To view your assets after trading ceases, please ensure you have not selected “Hide small assets” in your Funds page.
• Deposits of SOS after 8:00 UTC on May 13, 2022 will not be credited to your account.
• Withdrawals of SOS from Phemex will continue to be supported

We thank you for your support as we continue to build the crypto ecosystem in a way that promotes transparency and long-term, sustainable growth.
