You can use this guide to see what's best, but I just bought some stainless steel plates and engrave them myself. https://jlopp.github.io/metal-bitcoin-storage-reviews/

Okay, so now, how about the availability of the information. Is your seed phrase on your device of choice acceptably available to you? How about if your house was broken into? How about if your house burned down? Consider all the things that could harm the availability of your seed phrase to you, without sacrificing the confidentiality of that information. A steel plate that can survive a house fire https://jlopp.github.io/metal-bitcoin-storage-reviews/ can increase your availability, but does it sacrifice confidentiality? How about if its kept in a safe? How about, geodispursed mutli-sig with steel plates that are also geographically dispersed? Its a good trade off between availability and confidentiality and you can read more about it here: https://glacierprotocol.org/docs/overview/multi-signature-security/

If you want true cold storage then best option would be generate a wallet offline. Make note of the seed phrase. Check this seed phrase is correct and can recover the wallet! Then backup seed on steel hardware like a cryptosteel or other method of your choice from this list. https://jlopp.github.io/metal-bitcoin-storage-reviews/

Download the offline version of the BIP39 tool via https://github.com/iancoleman/bip39/releases/latest. Right click on bip39-standalone.html and save the file.

You could make this with a Raspberry Pi Zero and the stand-alone version of the Coleman Web page+javascript https://github.com/iancoleman/bip39/releases/latest/

Since what I just said may be confusing... here it is in practice with a link so you can try it for yourself using Ian Coleman's Mnemonic Code Converter:

With Christmas coming around and the bull market upon us, I thought it would be a good time to remind everyone one about the art of mnemonic memorization. The idea is you take a BIP39 seed, then make a poem, story, limerick, or song using the words to help you remember. If you gift bitcoin, you can include the writing with the seed-card you provide to help the recipient remember as well. If you want to play along, go to Ian's BIP39 page and generate a valid seed mnemonic then see if you can't create a blurb of text that includes all the words.

You can try Ian Coleman's tool at : https://iancoleman.io/bip39/

13) Go to https://iancoleman.io/bip39/. There you need to change "Coin" value of the dropdown to "ETH – Ethereum". After that you can paste Secret phrase associated with Key 1 to “BIP39 Mnemonic” section

As I learned how to build websites, I wanted to use my new skill to help the crypto community in any way I can. So, I made a wallet generator website. It's like iancoleman BIP39, but with a nicer and more user-friendly design inspired by Tornado Cash, a simple way to make wallets from files/images, and support for Monero!
