Research VS bip39

To verify UR:CRYPTO-HDKEY - https://github.com/BlockchainCommons/Research/blob/master/papers/bcr-2020-007-hdkey.md

I am very sure it won't be. Trezor and Keystone use SLIP-49 which has some shortcomings which were improved upon by SSKR.

SSKR is an improvement on SLIP-39. SSKR comes with a seedtoolcli. Tezor hardware wallets use SLIP-39 if you have one of those.

SLIP-0039 is not is not round-trip compatible with BIP-0039. SSKR / BCR-0011 is based on SLIP-0039 but improves upon it by adding this compatibility.

BCR-0011 aka Sharded Secret Key Reconstruction (SSKR)

Please see the discussion here: https://www.reddit.com/r/ledgerwallet/comments/ibkls4/does_ledger_have_plans_to_implement_shamir_secret/ Maybe ask here if the Ledger developers nicely if they still plan to implement Shamir's Secret Sharing, If Ledger do not implement Shamir's Secret Sharing (e.g. SSKR) then maybe consider purchasing a Trezor which implements SLIP-39. Bear in mind that SLIP-39 is not round-trip compatible with BIP-39.

Or use a single hardware wallet that implements a version of Shamir Secret Sharing (SSS) e.g. SSKR and store your steel share backups in multiple locations.

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!
