It’s straightforward to generate a file system wallet form a seed phrase:
$ solana-keygen recover 'prompt:?key=0/0' --outfile ~/.config/solana/id.json
But Phantom only has ONE seed phrase even if you have multiple wallets. When I use the command above, it generates a keypair for the first wallet in Phantom, but it’s not the one I’m trying to recover.
How do I create a file system wallet / keypair in this situation?
