Keep it safe and backed up. Once “escape mode” is activated, you’ll have full control of your assets. We'll no longer provide custody services. If your wallet address is flagged as a “black address,” you can only escape or deactivate the wallet—you won’t be able to continue trading. Before making changes, we recommend backing up the private key or seed phrase of your target Externally Owned Account (EOA).
