Hello, apologies for the delayed response. As of now if you import your already existing wallet on the FX wallet app into MetaMask the 0x address that you get in MetaMask is something separate from your f(x)wallet address. However with the upgrade we have been working on as seen in this thread, the 0x address will be connected to the new fx address (after migration), and the funds you have will also appear on the 0x address. Hope this answer helps
