Does anyone know of any good hardware wallets that are open source? I've been using a Ledger Nano for years but not being open source is a deal breaker for me. With the Ledger Recover feature meant to help restore people's private keys/seeds by complying with KYC, the hardware wallet could be compromised as we know it. If it's not open source, it cannot be trusted.

Any suggestions and/or recommendations would be greatly appreciated. Thanks in advance.
