How much was lost in the Vauld hack?

The Vauld hack resulted in — in losses on July 04, 2022.

What attack technique was used in the Vauld exploit?

The Vauld exploit utilized Other. Understanding this attack vector is critical for smart contract auditors and developers building secure DeFi protocols.

How can developers prevent similar smart contract attacks?

Preventing smart contract hacks requires a combination of secure coding practices, thorough security audits, and understanding common attack vectors like reentrancy, oracle manipulation, and access control flaws. Smart Contract Hacking (SCH) provides hands-on training to help developers and auditors identify and prevent vulnerabilities before deployment.

Incident Overview

Quick Summary

On the 4th of July 4 2022, the trading and lending platform Vauld freezed user withdrawals.

Details of the Case

Vauld faced financial challenges due to market conditions, such as the Terra Luna crash and paused withdrawals by Celsius, and financial difficulties of the platform’s key business partners.

Following withdrawals from Vauld of about $200 million that happened in 25 days after Terra's case, the platform’s management decided to stop all deposits and further withdrawals.

What the Attacker Needed to Succeed

Understanding the prerequisites for this type of attack helps auditors identify protocols that are most at risk and helps developers build better defenses.

Technical Knowledge Deep understanding of other and Solidity and EVM internals

Capital Required Seed capital to cover gas and initial position setup

On-Chain Access Ability to interact with smart contracts and deploy a custom exploit contract

Protocol Analysis Identification of the exploitable vulnerability in Vauld's contract logic - root cause: cefi

Execution Speed Precise transaction ordering and timing to exploit the vulnerability within a single atomic block

Obfuscation Plan A strategy to launder and move stolen funds - typically through mixers, cross-chain bridges, or decentralized DEX swaps to resist tracing

What Auditors Should Check

Could this have been caught in audit? Likely — with a thorough Other audit checklist and test coverage

If you're auditing a protocol with similar architecture to Vauld, these are the critical security checks that could have prevented this incident (July 2022).

Verify all logic paths related to Other are guarded by proper access controls and input validation
Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
