Yoroi Wallet Recovery Service

Yoroi, Emurgo's wallet for Cardano, was renamed SecondFi in April 2026 and is now shutting down after a security incident — what that means for your wallet is below. Separately, the wallet comes in more than one recovery-phrase length: Yoroi normally uses 15 words, Daedalus and Lace use 24, and Cardano's older Byron wallets used 12 — only the matching length opens your funds.

Yoroi is now SecondFi, and it is closing

EMURGO renamed Yoroi to SecondFi in April 2026. Between 21 and 23 June 2026 about 16.1 million ADA was drained from 374 wallets, and EMURGO has said the service will not resume normal operations. Two things follow for anyone still holding one of these wallets.

• Move out, to a Cardano wallet you create yourself with a new recovery phrase. The old words do not belong in the destination.
• For an affected address, restoring the same phrase elsewhere does not remove the exposure. SecondFi's own guidance is that compromised keys stay exposed after an import, so those cases run through EMURGO's official recovery process.

Hardware-wallet setups are a separate case: SecondFi's assessment is that they were not affected, because the keys never left the device.

What this covers

• Restoring a Yoroi wallet from its 15- or 24-word phrase in a maintained Cardano wallet.
• Forgotten spending passwords: the phrase resets them.
• Zero balance after restore: usually the wrong phrase type or era (Shelley vs Byron).

Zero balance after restore

• A 15-word phrase and a 24-word phrase are different backup formats. Use the words exactly as recorded and identify the original wallet and era before choosing a restoration method. Do not add, remove or substitute words just to select another length.
• A 12-word phrase is Byron-era and will not import into Yoroi at all - that phrase belongs in Daedalus (or another wallet that still reads the legacy Byron format), not in a search for what Yoroi is doing wrong.

What is impossible

• No phrase and no local wallet data. Yoroi does not store your phrase anywhere, and there is no reset.
• 12-word Byron phrases cannot be imported into Yoroi; depending on the wallet, they may be recoverable elsewhere.

Spending password vs recovery phrase

The spending password protects the local wallet file; the 15- or 24-word recovery phrase is the real backup. Losing the password does not lose the wallet - restoring the phrase in a current Cardano wallet sets a fresh password. Losing the phrase, with no backup, is the hard case.

Practical notes

• Yoroi is a light wallet, so a zero balance after restore is almost always a phrase-type or era issue, not a sync delay.
• Staking rewards accumulate in a separate reward account linked to the wallet’s staking key, not at its ordinary receiving addresses. After restoration, check the rewards section in a compatible Cardano wallet and verify that the same staking account was restored.
