Import existing seed phrases or create a new wallet, you can also import a private key just like Unisat wallet

Tips: SatX Wallet is forked from Unisat's open-source code, and SatX cannot store users' private keys. Your private key is securely stored in your local browser and is called upon to sign transactions when needed

2. **Enter the CAT20 marketplace, select the CAT20 token you want to buy from the list**
