          <p>
            You are about to access an alpha version of MyCrypto that is currently in development.
            In its current state, it should only be used for testing, not for important
            transactions.
          </p>
          <p>
            Any wallets you generate should not hold a significant value, and any transactions you
            make should be for small amounts. MyCrypto does not claim responsibility for any issues
            that happen while using the alpha version.
          </p>
