Antwort auf: 1 Trezor-Erweiterung (Brieftaschenadresse) Link zu mehreren Brieftaschen
>Can I just link the same wallet address to my old ronin on my desktop and possibly to my metamask as well?
You can only have 1 seed phrase in your Trezor at a time.
You have 1 trezor-generated seed phrase with your new ronin wallet.
You have 1 pc-generated seed phrase with your old wallet.
So… you don’t want to put that pc-generated seed into the trezor because it won’t be trezor-secure (as it has been on a pc), and you can’t have both on the trezor anyway.
