About the Initiative

The Open Web Application Security Project (OWASP) has been the gold standard for web security since 2001. Their Top 10 lists have guided millions of developers in building secure applications.

As Web3 emerged, CredShields recognized the need to extend OWASP's legacy to smart contracts and blockchain technology. Through our SolidityScan platform and Web3HackHub incident database, we've analyzed thousands of contracts and security breaches.

Our comprehensive data on smart contract vulnerabilities and real-world exploits became a key input for the OWASP Smart Contract Top 10, helping establish the first industry-standard security framework for Web3.

OWASP Smart Contract Top 10

The most critical security risks facing smart contracts and Web3 applications in 2025.

SC01:2025 Access Control Vulnerabilities

Improper access controls allowing unauthorized users to execute privileged functions.

Real-world Example Poly Network Bridge Exploit - $611M
Critical

SC02:2025 Reentrancy Attacks

External calls that allow attackers to recursively call functions before state updates.

Real-world Example Poly Network Bridge Exploit - $611M
Critical

SC03:2025 Integer Overflow/Underflow

Mathematical operations that exceed variable limits causing unexpected behavior.

Real-world Example Poly Network Bridge Exploit - $611M
High

SC04:2025 Unchecked External Calls

Failed external calls that don't properly handle return values or exceptions.

Real-world Example Poly Network Bridge Exploit - $611M
High

SC05:2025 Denial of Service

Contract states or gas limit exploits that prevent normal operation.

Real-world Example Poly Network Bridge Exploit - $611M
High

SC06:2025 Bad Randomness

Predictable random number generation that can be exploited by attackers.

Real-world Example Poly Network Bridge Exploit - $611M
Medium

SC07:2025 Front-running

Transaction ordering manipulation in mempool for financial advantage.

Real-world Example Poly Network Bridge Exploit - $611M
Medium

SC08:2025 Time Manipulation

Reliance on block timestamps that miners can manipulate within limits.

Real-world Example Poly Network Bridge Exploit - $611M
Medium

SC09:2025 Short Address Attack

EVM padding behavior exploited through malformed address parameters.

Real-world Example Poly Network Bridge Exploit - $611M
Low

SC10:2025 Unchecked Return Values

Silent failures from external calls that don't validate return values.

Real-world Example Poly Network Bridge Exploit - $611M
Low

Why These Risks Matter

Web & Mobile App Threat Modeling

Instant & Irreversible

Unlike Web2, exploits in smart contracts are instant, irreversible, and on-chain. Once funds are drained, they're gone forever.

Web & Mobile App Threat Modeling

Enterprise Adoption

With Web3 adoption by enterprises and regulators rising, compliance with security standards is no longer optional.

Web & Mobile App Threat Modeling

Prevention is Key

Over $1.4B was lost to Web3 hacks in 2024, most linked to these exact categories. Prevention is the only protection.

Frequently Asked Questions

What is the OWASP Smart Contract Top 10?

A list of the 10 most critical smart contract vulnerabilities, adapted from OWASP's traditional Top 10, using Web3-specific exploit data.

How does CredShields contribute to the OWASP Smart Contract Top 10?

Access control issues, reentrancy, and front-running are among the top. Our data shows access control vulnerabilities alone accounted for 67% of losses in 2024.

What are Access Control Vulnerabilities?

Use automated scanning tools like SolidityScan, conduct manual audits, and follow secure coding best practices based on the OWASP Smart Contract Top 10.

How can I check if my smart contract is vulnerable?

It sets a global, recognized standard for risk awareness and prevention, critical for developer trust and enterprise adoption in the Web3 space.
