Chainswap Contract Vulnerability: $4.00M Reported Loss

·Historical incident record

Incident Overview

The cross-chain bridge Chainswap announced the details of the stolen incident on its official blog. A total of 20 project assets were stolen, with a total value of approximately US$4 million. At present, the ChainSwap team has reached a consensus with the affected projects and initially formulated and implemented a compensation plan. According to the project investigation, due to the error in the token cross-chain quota code, the on-chain swap bridge quota is automatically increased by the signature node, the purpose of which is to be more decentralized without manual control. However, due to a logical flaw in the code, this led to a vulnerability that automatically increases the number of invalid addresses that are not whitelisted.
