Goldfinch Wallet Hack Steals $330K ETH, PeckShield Issues Warning

PeckShield Alerts on Goldfinch Wallet Hack and Tornado Cash Laundering

Ever wonder just how secure your crypto is? The recent Goldfinch Wallet Hack proved just how dicey it could get. One user, deltatiger.eth, lost about $330,000 in Ethereum after a hacker gained access to their wallet.

The stolen funds included 118 ETH, sent by the attacker to Tornado Cash, a service providing crypto flow concealment. 

PeckShield, a blockchain security company, warned that everyone should revoke approvals immediately for a suspicious smart contract: 0x0689aa2234d06ac0d04cdac874331d287afa4b43.

What "Revoke Approvals" Means 

Anytime user interact with websites like Goldfinch, user permit smart contracts to transfer the tokens. And if that contract gets compromised, hackers can drain users wallet.

Revoking approvals is easy yet significant. It:

• Prevents risky contracts from touching tokens

• Protects wallet from future hacks

• Can be done with tools like Revoke.cash or Etherscan Token Approval Checker

Checking approvals now-even if user has never had a problem in this area-can prevent a lot of problems.

Why This Hack Is Part of a Bigger Problem

But this isn't just about one user account, AI is starting to play a role in crypto hacks. Researchers at Anthropic tested AI models like Claude Opus 4.5, Sonnet 4.5, and GPT-5 and showed that they could automatically exploit smart contracts. Using a tool called SCONE-bench, AI recreated past hacks worth $4.6 million and even discovered new vulnerabilities in fresh contracts.

AI reasoning through complicated steps, automated fixing of mistakes, and automatically generating exploits allows for quicker and more unpredictable threats of hacks.

Recent Similar Attack

Take the Yearn Finance yETH hack in November 2025. The attacker didn't directly break the code; the pricing of the vault was changed to withdraw more ETH than was deposited, and then the stolen crypto was laundered through Tornado Cash.

This shows that security isn't just about code; it's also about how tokens interact, how pricing works, and how liquidity is managed. Even trusted platforms can be prone to vulnerability if precautions aren't taken.

Why Goldfinch Users Should Take Action Now

• The hack of Goldfinch's wallet is another warning to everybody in DeFi: users should

• Revoke risky approvals immediately

• Be vigilant regarding wallet security.

Consider AI tools to monitor smart contracts. Goldfinch is still a pretty trusted platform that offers private credit funds on-chain, but an incident like this shows even the best platforms can't protect users who leave risky approvals active. Fast action will avoid losses and keep funds safe.
