Cardano (ADA)

I didn’t even know that Cardano had $20m in TVL!

CARDANO ECOSYSTEM ALERT: SecondFi has suffered a major exploit after attackers reportedly abused a flaw in its wallet generation software. According to SlowMist, the damage could be over $20M, including more than 129M ADA and other tokens. Users should migrate funds to a new wallet immediately.

🚨MASSIVE EXPLOIT IN CARDANO PROJECT DRAINS OVER $20 MILLION Cardano ecosystem project SecondFi has suffered a major exploit after a flaw in its wallet generation software allowed attackers to drain user funds. Security firm SlowMist says the total damage may exceed $20 MILLION, involving more than 129M $ADA and other tokens. Users have been urged to immediately migrate funds to a new wallet.

Are there any $ADA bulls left around here? All I get is hate and bearishness in my comments.

SlowMist: Cardano Ecosystem Project SecondFi Losses May Exceed $20 Million SecondFi, a Cardano ecosystem project, said the root cause of its recent security incident has been traced to an issue in its proprietary Cardano wallet generation software. The team stated it has completed on-chain analysis to assess the scope of the impact and is working with a blockchain security firm on an independent technical review. SecondFi's preliminary estimate puts the total impact at around 16 million ADA. SlowMist founder Cos (Yu Xian) said that based on the hacker's fund flows and wallet activity, actual user losses could theoretically exceed $20 million, involving more than 129 million ADA and other tokens.

Manwu Yuxian: SecondFi users may have lost over $20 million Manwu founder Yuxian posted that, based on on-chain behavior analysis, in the Cardano ecosystem project SecondFi security incident, suspected hacker addresses transferred a total of over 129 million ADA and other tokens, estimating user losses exceeding $20 million.

Wu said that he learned that the Cardano ecosystem project SecondFi has released investigation progress on the recent security incident, stating that the root cause has been identified as its native Cardano Web wallet generation software, and the impact has not exceeded that component. The team has completed on-chain analysis and is conducting an independent technical review with a blockchain security firm to verify the findings. It is currently estimated that the incident caused a loss of about 16 million ADA. SecondFi said the platform remains in security maintenance mode, has completed a snapshot of user balances, and is cooperating with Cardano ecosystem entities such as Input Output (IOG), Cardano Foundation, Intersect, and SundaeSwap to monitor exchange-related fund flows and reduce the impact on other protocols. https://t.co/0wwXDOSftr

Not your keys, not your...wait 😳 Self-custody just cost hundreds of Cardano users 16 million $ADA 😬 The wallet software itself was the backdoor oddly enough too @secondfiapp formerly Yoroi had a critical vulnerability in its native web wallet generation code Every single wallet it created was compromised! Blink Labs developer warning: "the wallets generated are all unsafe." Switch immediately SecondFi's response? Maintenance mode Paused front-end And this gem: "taken extraordinary steps to protect remaining assets where possible." That last part is key Translation: some users will not be made whole This is Cardano's ecosystem in June 2026: 🔻 TapTools shutting down after its entire leadership bailed 🔻 Summit 2026 cancelled because governance voted down the budget 🔻 JPG Store closed 🔻 $ADA falls out of top 20 first time EVER 🔻 DReps fleeing 🔻 Much of the community sick of Charles “I have more money than you” Hoskinson And now the wallet that was supposed to be the safe, self-custody option had compromised key generation from the start Self-custody means nothing if the software generating your keys is the attack vector So we are left with 16M drained
