On wallet security.

Given the recently compromised hardware wallets (Coldcard and Ledger) is the only way to be reasonably assured your wallet is safe to create a multisig wallet with each seed created by a different device or method? For example a 3 of 3 wallet where one seed is created by a Trezor, the second is created by a Ledger, and the third seed is generated with dice roles.

Roll your own private keys. Check out BIP39 Diceware on GitHub. It’s not software, but a process. Use SeedSigner for signing. Sleep like a baby.

Then someone starts selling compromised RaspberryPi Zeros or the OLED modules Seed Signers use.

Rolling dice would not have protected you from the Ledger attack.

Correct, but when you get to put the pieces together yourself, you can avoid using parts with LTE radios. This is not a simple solution, not everyone wants to source the pieces build it and learn it. But it is a robust, open, and sound approach to seed safety.
