Incident Overview

Quick Summary

The Treasure Swap project has been exploited by hackers. Using the vulnerability, the hacker needed only 1 wei to exchange all the $WETH tokens in the transaction pool.

Details of the Exploit

Treasure Swap is a donation protocol driven by the community to build a sustainable DAO.

The hacker noticed a vulnerability in the Treasure Swap contract, where in the swap function the check for the k-value of the constant formula k = a * b, which determines the price of the token (A) in the token (B), was skipped. The hacker noticed this vulnerability, deployed his malicious contracts on the network with which he began to steal the $WETH reserves from the protocol.

Example transactions of the exploit:

2) https://bscscan.com/tx/0x90a8e176…80c92d

3) https://bscscan.com/tx/0x0b13710a…fc219c

All stolen $BNB are still held on the hacker's wallet.

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 Treasure Swap's contract logic - root cause: exchange (dex)
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 Treasure Swap, these are the critical security checks that could have prevented this incident (June 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
