Can anyone tell me how to access my ada? It’s on a 21 word phrase paper wallet. Can’t seem to find any way of restoring this wallet? Thanks!

21 words? Where did you get that seedphrase from?
You can still claim it in Yoroi.
You need to have a (usual) wallet and you need to switch to “Yoroi old version” in the “General” tab of the settings.
Then you get an option to “Claim/Transfer” Yoroi paper wallets:

As the title says: It’s a Yoroi paper wallet as they offered it until 2020 (actually longer, I remember having seen that option when I first came to Cardano in 2021).
Since they cannot be created anymore, I cannot test if they use the standard algorithms and just an odd seed phrase length (which is totally possible, seed phrases can just be any multiple of 3, theoretically) or if they do something more strange.

Wasnt remembering 21 word seedphrases anymore.

Many thanks for replying, how do I claim it in yoroi though? On the website? From what I can see, the website offers no link or option for what you mention? Tia.
You install the extension and import your wallet (or create a new one if you don’t have one that you want to use).
That screenshot is from the Yoroi wallet app.
Oh I see, so I think I understand now. So I have the Yoroi chrome extension, have tried to click on “Yoroi old version”, but it doesn’t do anything, and won’t select? I’ll add a picture on here if I can

Oh, I had that glitch also. It worked after reloading the page/extension for me.
Sorry, didn’t mention that because I thought it was just me.

Thanks so much for you help, you are an absolute star! I restarted chrome, followed your instructions and all is good! Hopefully this will be able to help others with same issue, maybe I’m just crypto illiterate lol!

No, you’re not. 21 word paper wallets are really rare nowadays and they really hid that option … and the added hurdle of the “old version” switch not reacting is the icing on the cake.

I also faced this problem, but this option is not available now, how can I restore.
@William.Emurgo Does Emurgo/Yoroi have anything in place for users of the old Yoroi paper wallets with 21 word seed phrases?
I’m facing exactly the same issue. No option to switch versions and restore.
@Mohammad_hossiny and @Randomix
do you know if these seedphrases are for Byron era wallets or for Shelley era wallets?
According to old Internet sources (https://shift.infinite.red/gifting-cryptocurrency-to-kids-c9c5a4644f31#89cc), they were Byron wallets (Ae2… addresses) derived from 21 word seed phrases plus a password.
Yes that’s correct.
So, there might perhaps be a way to do it independently of Yoroi: There is https://github.com/IntersectMBO/cardano-addresses which implements a lot of historic and current Cardano derivation methods. And I can derive some Byron Ae2… address with it from a 21 word seed phrase with an additional password/passphrase:
cardano-address key from-recovery-phrase Icarus --passphrasehopefully does what Yoroi did pre-Shelley to derive a root key.cardano-address key child 44H/1815H/0H/0/0should derive the the first address of the public chain of the first account,1815His ADA and44His used for the purpose in the derivation path since https://input-output-hk.github.io/adrestia/cardano-wallet/concepts/address-derivation says that Yoroi/Icarus were using that during Byron.cardano-address key public --with-chain-codejust derives the extended public key from the private key andcardano-address address bootstrap --network-tag mainnettells us the corresponding address for that public key.
I have no idea if that is what Yoroi did back in the day to derive the key pair and the address for their paper wallets (it is one standard-compliant way to get a key pair and address, they could have chosen another derivation path, handled the passwords slightly differently, whatever) and I do not have an old paper wallet to test that.
If it is, you would still have to find some way to use the private key that is now known to actually move the funds to a current wallet. None of the wallet apps with a nice UI can do it. So, you either use cardano-cli for that (.skey and .vkey for that can be created from the addr_xsk1…) or you program something using one of the Cardano libraries.
So, still a rather slim hope. And you would have to either not be intimidated by all that tech stuff yourself or have access to a really trustworthy Cardano nerd. Never give your seed phrase and/or password to random dudes on the Internet including us!

So it seems like the missing feature comes back in with the version 5.4.400 (probably released next week). I think its best to wait until that happens so you can safely access your funds again.
