Decentralized exchange aggregator 1inch recently faced a significant security challenge but successfully recovered the majority of $5 million stolen during a breach.
-
The breach was a direct consequence of an outdated smart contract, affecting a third-party market maker while the end users remained unscathed.

“After negotiations with the hacker, most of the $5 million stolen from 1inch has been returned, with the hacker keeping a portion as a bug bounty,” reported WuBlockchain, relying on Decurity’s thorough investigation.
This article delves into the recent security breach of 1inch, highlighting the recovery process of stolen funds and the critical need for enhanced security measures in DeFi platforms.
1inch Recovers Most of Its Stolen Funds
1inch encountered a serious security incident on March 5, caused by a vulnerability in an outdated version of its smart contract system. Following intensive discussions with the hacker, the platform managed to reclaim the majority of the $5 million that went missing.
“After negotiations with the hacker, most of the $5 million stolen from 1inch has been returned, with the hacker keeping a portion as a bug bounty,” announced WuBlockchain, in line with findings from Decurity’s meticulous postmortem report.
As detailed in a blog post by 1inch on March 7, the exploit was rooted in a flaw within the Fusion v1 resolver smart contract, which is no longer active on the platform. The breach was identified shortly after 6 PM UTC on the day it occurred and illustrated how attackers can manipulate outdated logic to carry out unintended transactions.
Crucially, no end users were harmed in this episode, as the exploit primarily targeted a third-party market maker known as TrustedVolumes. Once the breach was detected, 1inch promptly redeployed its resolver contracts to mitigate the potential for further attacks.
According to the thorough analysis in Decurity’s report, onboard messages from the hacker indicated a willingness to negotiate for a bug bounty in exchange for the return of the stolen assets. This negotiation led to TrustedVolumes working out a deal with the attacker, allowing for a rare recovery of stolen funds in the decentralized finance (DeFi) space.
This incident marks a pivotal moment in the realm of DeFi, showcasing the rising inclination towards ethical hacking practices and amicable resolutions in the face of security breaches.
Security Remains a Major Challenge for 1inch
This event represents the second significant security breach experienced by 1inch in the past six months, following a front-end compromise due to a supply chain attack in October 2024. This recurrent issue emphasizes the inherent risks associated with DeFi protocols and the critical need for ongoing monitoring and rapid response strategies to protect assets and user investments.

Despite the successful recovery process, the market did not react dramatically, with the 1INCH token experiencing a modest increase of only 1.12% following Sunday’s session, trading at approximately $0.23 at the time of writing.
This situation reiterates the paramount importance of conducting regular smart contract audits and embracing proactive vulnerability detection measures, alongside the implementation of robust validation mechanisms aimed at preventing similar occurrences in the future.
Conclusion
The recent breach at 1inch serves as an urgent reminder of the necessity for heightened security protocols within the DeFi industry. As platforms navigate the complexities of blockchain technology and smart contracts, it is essential that they invest in advanced safety measures and uphold transparency in their operations. The incident acted as a bolster for the ongoing dialogue surrounding ethical hacking and the importance of robust response strategies to combat ever-evolving threats. Moving forward, the industry must prioritize security to retain user trust and ensure broader adoption of decentralized finance solutions.
