Smart Contract Security

Smart Contract Audit for
DeFi and Web3 Protocols

Smart contracts are immutable once deployed, a single vulnerability can drain millions in seconds, with no way to roll back. Femto Security's smart contract audit combines automated static analysis, expert manual review, and proof-of-concept exploit development to find critical flaws before your protocol goes live. Trusted by DeFi projects, NFT platforms, and Web3 founders across the UAE and GCC.

Frequently Asked Questions

Common questions about our smart contract auditing services

What is a smart contract audit?
A smart contract audit is a systematic review of blockchain-based code to identify vulnerabilities, logic flaws, or security risks before deployment. It ensures that contracts function as intended and are resistant to exploits.
General
Why are smart contract audits important?
Smart contracts handle significant financial transactions in DeFi, NFT projects and Web3 applications. A single flaw can lead to financial loss, exploits, or reputational damage. Audits help prevent these risks.
Security
What does a smart contract audit include?
Audits include code review, security testing, functional verification, automated vulnerability scanning, and manual expert analysis. The goal is to detect logic errors, reentrancy attacks, access control issues and other critical vulnerabilities.
Process
How is a smart contract audit conducted?
Auditors perform both automated analysis using tools and in-depth manual reviews. They map contract logic, simulate potential attack vectors and test integrations with other smart contracts and blockchain networks.
Methodology
What types of vulnerabilities are commonly found?
Common issues include reentrancy vulnerabilities, integer overflows/underflows, improper access control, unhandled exceptions, timestamp dependencies and logic errors in tokenomics or governance mechanisms.
