The decentralized exchange aggregator 1inch Network, in collaboration with the cybersecurity platform HackenProof, has released its comprehensive vulnerability bounty report for the first half of 2026. According to the document, the initiative received a total of 1,055 bug reports across six core security programs, resulting in 32 rewarded submissions. This proactive security measure highlights the project's commitment to maintaining a robust infrastructure within the decentralized finance (DeFi) ecosystem.
Breakdown of Security Audits and Vulnerability Distribution
The report details the distribution of bug reports across various components of the 1inch ecosystem. The shared liquidity layer, known as Aqua, attracted the highest level of scrutiny from white-hat hackers, accounting for 472 reports, of which 9 were deemed eligible for rewards. The core smart contracts, which facilitate cross-chain swaps and liquidity aggregation, received 267 submissions with 3 receiving payouts.
- The Business sector recorded 111 reports, with 9 rewarded for identifying potential risks.
- Security researchers submitted 85 reports regarding the 1inch Wallet, resulting in 6 rewards.
- The Web terminal interface saw 68 reports, though only 1 was verified for a bounty.
- Infrastructure components received 52 reports, leading to 4 successful reward claims.
Strengthening DeFi Resilience through Collaborative Security
All identified vulnerabilities highlighted in the H1 report have been officially patched and resolved by the development team. By leveraging the HackenProof platform, 1inch utilizes a crowdsourced security model to identify edge-case bugs that traditional audits might overlook. Bug bounty programs have become a standard industry practice for protocols managing high Total Value Locked (TVL) to prevent exploits and financial losses.
The systematic review of these reports ensures that our smart contracts and user interfaces remain resilient against evolving threats in the blockchain space.
The successful resolution of these 32 rewarded cases demonstrates the effectiveness of the 1inch H1 Vulnerability Bounty strategy. By incentivizing the global security community to stress-test their protocols, 1inch continues to bolster user confidence in its liquidity aggregation services and non-custodial wallet solutions. These efforts remain critical as the project scales its operations across multiple Ethereum Virtual Machine (EVM) compatible networks.
