SecondFi Is Shutting Down: Official EMURGO Recovery Update

EMURGO has shared a new update on the SecondFi security incident, including the patched vulnerability, wallet status checks, recovery work, hardware wallet migration paths, and confirmation that SecondFi will not resume normal operations.

In this video I break down what has been confirmed so far, what users should watch for next, and why official-channel verification and safer wallet migration matter right now.

Key points covered:

  • EMURGO says the identified vulnerability has been patched while further reviews continue.
  • Fund recovery and asset protection remain the immediate priorities.
  • A quarantine/status-check process is expected to help users verify whether their wallets were affected.
  • SecondFi is effectively ending in its current form.
  • Hardware wallet migration is now the practical path for users who want stronger custody hygiene.

It’s genuinely sad to hear that a platform within the Cardano ecosystem is shutting down.
Since Yoroi was my very first wallet, I’ll certainly miss it. That said, I agree that security patches and asset recovery must be the top priority right now. I truly hope that all the affected community members can get their funds and assets back as soon as possible.

On the other hand I wanted to move to Lace anyways, the event just accelerated the change. NIGHT thawing was the only reason to stay with Yoroi.

It is important now that the impact is better published and users of Yoroi get information about what they should do. E.g., on reddit there are lots of people confused by the messaging and going into a “distrust everything” mode.

What I still miss, is some information since when the vulnerability existed; from the very beginning or at some later point in time. That’s very important for long time users of Yoroi; they need to know if they are vulnerable or not.

There are different ways to secure your money; a checklist and given procedures would help. Even for people without HW wallet.

Same, I used Yoroi and did countless video tutorials on how to use the wallet in the early days. Sad times indeed.

Vulnerability same about with the switch over to SecondFi.

A library was included which was experimental at best which lead to the hack being possible.

Users that interacted on SecondFi between the launch and the lock down could have been compromised.

Exposure only happens once you do a transaction.

All wallets, newly created and restored ones in the app are impacted.

16M funds were initally taken by the hacker.
129M by a white hat hacker.

It’s a process to identify who owns what and what assets go to which new wallets.

Hence they’re trying to get people to stick with secondfi/yoroi to funnel them through the recovery process.

16M is being put up by Emurgo, from what I understand, and the white hat hacker has the ability to send all the other funds back to users too.

I’m also somehow missing much more information about what happened when.

They still claim that only 16 million ADA were affected.


But I can see at least three addresses/accounts of the original attacker on 21st June:

All three became active in the exact same block at 2026-06-21 20:29:41 UTC, all three show the same pattern of emptying victim addresses, exchanging ADA for USDCx, and finally funneling those USDCx out.

As far as I can see, more than 16 million ADA went through these three addresses.


Then, there is this address/account:

https://adastat.net/accounts/15379180b22573b8397a7e576cead9af6a36cf2902ac8aa4b2f35161: stake1uy2n0yvqkgjh8wpe0fl9wm82mxhk5dk09yp2ez4ykte4zcgg2e9m5/addr1q8g8cgwqw98q2mrzrwgcy3wectdxwem8a8zp9r2mn6wjy7q4x7gcpv39wwurj7n72akw4kd0dgmv72gz4j92fvhn29ss7vuz99

First used 2026-06-22 17:34:04 UTC, around 130 million ADA were transferred through this one. Most plausible is that this is the one where Emurgo claims that they “rescued” user funds.

Interesting is that they then have to have known pretty exactly what the problem was already at that time, 12 hours before they posted this:

And it wouldn’t make much sense why they would give a different reason (web wallet generation) a couple of hours later then:


Finally, there is also this address which seems to have drained some vulnerable addresses, but never moved the 4 million ADA further:

https://adastat.net/accounts/2391d456761f8f76bc3a1743273d755468cf47ad2ed03b2aa9ed5405: stake1uy3er4zkwc0c7a4u8gt5xfeaw42x3n6845hdqwe248k4gpgdq4da5/addr1q8m5wdncq7rwum73r5cyyr82qx2xjem5k4ehapl3wy36aaerj829vasl3amtcwshgvnn6a25dr850tfw6qaj420d2szsslkku6

Only used from 2026-06-23 05:20:53 UTC until 2026-06-23 06:53:23 UTC. Maybe a copycat?

I’m not sure if this is good news or bad news, but it’s going to be quite difficult for SecondFi to rebuild trust in the community after that incident

There are many copycats now.

Security experts revealed how the hack was done and people vibe coded a copy cat hack.

I believe they’re allowing for the snapshot from the time they closed their app and put it in maintenance mode. Any funds after that were not done via SecondFi. May have been caused by if but users moving to another wallet would have exposed them at that point.

I suspect that is the reason why they capped it at 16M.

The other 129M is from the white hat hacker that worked out how it was being done and ‘saved’ the rest before the hacker could get more.

Watch out for the email scams too, thats draining people as well. That wouldn’t be covered with the recovery process.

I think it would be impossible, hence they’re shutting it all down.

Sad, they have been on Cardano with Yoroi from the beginning.

I heard that Levvy is shutting down too

Yeh, at least it’s not because of hacks or vulnerabilities. Due to better competition and products from Surf, FluidTokens and Liqwid. Better platforms and better returns attract users.

The request for a clear migration checklist seems especially important. Ideally, affected users need separate guidance for software-wallet migration, hardware-wallet migration, token and NFT verification, staking status, and avoiding recovery-related phishing.
It would also help if every step clearly distinguished between importing an existing seed and creating a completely new wallet, since those actions have very different security implications.

Are old yoroi wallets also vulnerable? I have two wallets from about 4 years ago that I haven’t touched in a long while, would they be considered safe or should I make new wallets? I’ve since imported them in eternl

You can check the addresses on: https://checker.secondfi.io/

As far as I know, the horribly broken transaction signature was only introduced after (or when?) they upgraded from Yoroi to SecondFi. So, you should be safe if you never did any transaction in SecondFi, only in Yoroi years ago.

To be clear: Old wallets and even wallets originally created in other wallet apps can vice versa very much be vulnerable if a transaction signature was done in SecondFi. The keys were leaked when SecondFi signed and submitted transactions for them. Doesn’t really matter when and where the wallets were first created.

But: It seems that almost all vulnerable addresses were already emptied. Either by the attacker or by the rescue operation (for which I still find it very much unclear if Emurgo themselves did that or some white hat hacker later cooperating with Emurgo).

Title: ADA stolen shortly after SecondFi maintenance ended — Did anyone else experience this exact sequence during the Yoroi→SecondFi Chrome extension update?

I am a Japanese ADA holder and I would like to share my exact experience and find others who went through the same process.

June 18, 2026 — I opened the Yoroi Chrome extension as usual. It had become “SecondFi (formerly Yoroi)” and I pressed the button to update. During the update process:

  1. I was asked to enter my spending password (PIN) → I entered it
  2. My recovery phrase was displayed on screen — but at this point, my ADA balance was NOT shown
  3. The app then asked me to INPUT my recovery phrase
  4. After I entered it, my ADA balance finally appeared and I felt relieved

June 23, 2026 — My ADA balance was still showing normally in the SecondFi wallet.

After June 23, SecondFi entered long-term maintenance mode.

Shortly after the long-term maintenance ended, ALL of my ADA was sent to what I believe is a hacker’s address.


My questions:

  • Did anyone else go through this exact same sequence during the Yoroi→SecondFi Chrome extension update in June 2026? (recovery phrase displayed with no balance shown → then asked to input recovery phrase)
  • Did anyone else have their ADA drained shortly after the SecondFi maintenance ended?

I have already submitted a support ticket to SecondFi. Any information or shared experience would be greatly appreciated.

Did you at any point between 18th and 23rd June do any transaction (which could also be, e.g., just withdrawal of staking rewards)?

The vulnerability we know up to now depends on a transaction being signed by the affected version of SecondFi. If you did not sign a single transaction, yours must be something else.

Did you check the history of your address/account on an explorer? Are you sure that the drain happened after maintenance mode and not during maintenance mode?

That would be rather unusual. Almost all drains possible due to the vulnerability happened early on between 21st and 23rd June, either by the attacker or by the person allegedly “saving” wallets at risk.

No, I did upgrade from Yoroi to the SecondFi app on June 18, but I haven’t conducted any transactions since then—including receiving rewards. Therefore, on the day of the hack, the hacker performed the following actions: “delegation,” “receipt of rewards,” and “transfer of the entire balance after receiving rewards.” It’s frustrating to think that, since SecondFi had entered a long-term maintenance period anyway, if they had asked me for prior confirmation before ending the maintenance, we might have been able to prevent this damage.

No.
I was never asked for pass phrase. The app logo just changed. I opened it and saw they partnered with Base. Then I immediately uninstalled since it’s owned by Brian Armstrong and anything that Brian or Andreessen or SBF or Altman or Sun… are involved in just extracts value and is antithetical to values of crypto and cypherpunks.

I strongly recommend always staying away from these.

Also, screw which ever project manager at Emurgo decided to just signs us all up with these scum.

I guess we add name VINEETH BUVANAGHIRI to the list of henchmen for the charlatans of crypto and stay away from anything he is involved in as well.

Hope your funds are safe and it was only visual or update glitch @okawallet
