Forgive me if this has been brought up before, I attempted to use the search feature and didn’t see anything related to this specifically. If I am just bad at search, do not hesitate to shame me.

I am looking to beef up the security of my bitcoin storage. I have the parts to build my own stateless seed signer, which is an important step up (imo) from relying on a prebuilt hardware wallet, but I fear I have put the cart before the horse.

I want to generate a new seed phrase/private key, preferably trustlessly and without the use of any digital RNG. I am aware of the two following options: -dice rolls -bag of chips, each with a different word from the bip39 wordlist

Am I missing any? Are there better options? Even if the options are more esoteric, I’m willing to learn.

Thanks for reading and for any helpful input.
