SecondFi Pulls 129 Million ADA Out of Harm’s Way After Wallet Exploit

SecondFi, the Cardano wallet formerly known as Yoroi, confirmed that three external attacks drained 16 million ADA, roughly $2.4 million, from 374 wallets.

The team then secured another 129 million ADA before attackers could touch it, moving those funds to a third-party custodian.

The headline number here is the rescue, also the theft. Eight times more ADA was pulled to safety than was actually stolen.

SecondFi traced the root cause to its own native Cardano web wallet generation software. The Cardano blockchain was not hacked.
