Crypto protocols lost hundreds of millions of dollars to smart contract failures in 2025. Now, the OWASP Smart Contract Security Project has released the OWASP Smart Contract Top 10 2026, a forward looking framework aimed at identifying the most common ways smart contracts are breaking in the real world.
The 2026 edition is based on structured analysis of smart contract incidents from 2025 and prior years, reflecting exploit patterns that have repeatedly led to major losses across DeFi, bridges, and onchain governance systems.
CredShields, supported by its research platforms including SolidityScan and Web3HackHub, led the incident pattern analysis that informed this year’s ranking.
Unlike theoretical vulnerability lists, the 2026 Top 10 focuses on how contracts are actually failing in production.
Where Smart Contracts Really Break
The highest ranked risks for this year suggest that crypto’s biggest problems are no longer just coding mistakes. They are structural.
Among the top risks:
In many 2025 incidents, attackers didn’t exploit broken cryptography. Instead, they exploited:
In other cases, contracts worked exactly as designed but the economic assumptions embedded in them failed under stress.
Price oracle manipulation and cross chain timing discrepancies enabled multi million dollar extraction events. Cross chain MEV exploits showed how attackers could front run transactions before they even reached destination networks.
The pattern is increasingly clear: a protocol can pass an audit and still fail in production.
This Matters for DeFi
The 2026 ranking is built from real exploit data and aims to highlight where protocols are most likely to break next.
For builders, that means moving security upstream from patching bugs after deployment to modeling risk before capital is exposed.
For investors and users, it reinforces a harder truth: “audited” does not automatically mean “resilient.”
As on chain systems become more interconnected and capital continues flowing into DeFi and tokenized assets, standardized risk frameworks are becoming more important across:
Beyond Contract Code
The release also acknowledges that some of 2025’s largest losses stemmed from operational and governance failures, including multisig compromise, rushed proposals, and supply chain exposure.
An accompanying “Alternate Top 15 Web3 Attack Vectors” expands the lens beyond contract code alone underscoring that smart contract security is only one layer of crypto risk.
The full OWASP Smart Contract Top 10 2026 framework, methodology, and supporting data are available on the official OWASP Smart Contract Security Project page.
