Here’s How Project 0 Saved User from $3M DeFi Wallet Hack

Project 0 (P0), a DeFi-native prime brokerage, has demonstrated the real-world value of rapid-response infrastructure after helping a user recover $3 million from a wallet compromise triggered by a phishing attack.

How Project 0 Stopped a $3M Loss

The incident began when the user clicked a malicious link while attempting to access Raydium. Within seconds, an attacker gained control of the wallet and drained nearly all accessible funds.

In many similar cases, victims have little to no recourse. This time, however, a significant portion of the user’s holdings remained protected within Project 0.

Moreover, Project 0’s evolved account architecture prevented the attacker’s drainer function from accessing the $3 million stored on the platform. The user quickly contacted the team, who responded immediately despite being on an off-site trip.

The team halted their travel plans, gathered at an airport, and began building a solution on the spot. They designed an account transfer tool that would allow the user to move funds using their seed phrase. After testing the system with their own money, they confirmed it worked and built a simple interface for the user.

Engineering a Real-Time Rescue Under Pressure

A major obstacle soon emerged. The attacker had reassigned ownership of the compromised wallet to a custom program, blocking the user from signing transactions, a critical step required to move funds.

Notably, the Project 0 team adapted quickly. Within two hours, they updated the transfer mechanism to support a separate key pair as the fee payer. This allowed them to fund a third wallet to handle transaction costs and complete the transfer process.

However, the funds were successfully transferred to a new account controlled by the user’s secure wallet, preventing what could have been a total loss.

MacBrennan, founder of Project 0, emphasized the impact of the intervention:

“If this user WASN’T using P0, they would’ve lost $3M. Because they DID have their money in P0, every penny of it was saved.”

Nonetheless, the incident highlights a growing divide in DeFi between passive infrastructure and active support systems. Project 0’s response shows that user control and real-time assistance can coexist and, in critical moments, make all the difference.
