Is there a way I can use a single seed for all my cryptocurrencies?

So Ledger gives us the ability to use a single 24-word seed for all cryptocurrencies you'd like to hold, which is quite convenient. However, I've been having some trust issues with Ledger lately and the Secure Element (and having to plug an USB device every time I want to make a new tx) makes me feel even more insecure.

I currently have all my crypto holdings anonymized through mixers, Tor, coinjoins, Whonix etc so that all links to my identity are broken; my computers are all running fully free operating systems.. so plugging in a device with a non-open-source component, especially since the device is specifically created for crypto transactions, might be a mistake privacy-wise.

Now I have a few other cryptocurrencies I'm holding besides BTC but I was wondering if there was a way to have only a single seed for all those coins besides Ian Coleman's tool. I have so many papers with a different seed on each for every coin, which becomes quite annoying at one point.. so I thought if there was a way to replicate what Ledger's done with the 24-word seed, it'd be so much easier to use the same one for all my coins.

Any ideas?

It'll probably depend on what coins you're planning on using as there will likely be many ways to do this.

Have you thought of using a trezor? Their schematics are online so you could probably get stuff printed yourself -although there's still the usb component.

Electrum ltc and electrum btc along with mew/metamask are compatible with the 24 word seeds though of the same type afaik (youll have to tick a box in electrum to make it use the appropriate bip for reading the seed). Waves also has a 24 word seed as well as decred which I *imagine* will be compatible with each other.


SECONDARY THOUGHT: you could try using a dex like bisq if you trust the developers enough to handle the transactions and attempt to use the same seed with mew in order to get erc20 tokens if necessary. You and your seed would be the full custodian you'd just be sending stuff signed by your machine across the network using their software and trusting them to not intercept it, bisq is cheaper than the waves equivelant but doesn't look as streamlined yet (but that could just be me).

Yeah! It is possible to have same seed for most of the cryptocurrencies. BIP-44 defines the hierarchy of deterministic wallet or popularly known as derivation path, however, it has only allocated coin_type value for Bitcoin and Bitcoin testnet. Hence, SatoshiLabs steps forward and defines the derivation path for other coin types in SLIP-44. You can visit here to see hardened child used as per SLIP-0044: https://github.com/satoshilabs/slips/blob/master/slip-0044.md

I am not sure about secure wallet which can provide you the access to all coins you needed but one thing is sure, if wallet supports mnemonic seed as defined in BIP-39 then you can import same seed you use for bitcoin for that wallet/coin as well.
