Why Smart Contracts Need Audits
Smart contracts form the backbone of decentralized finance (DeFi) and Web3 applications, but their immutable nature makes security critical. A single vulnerability can result in millions of dollars in losses. At walletr, we take this responsibility seriously through multi-layered audit processes.
Critical Insight: 68% of major DeFi hacks in 2025 were due to unpatched vulnerabilities found in smart contract code.
Our Multi-Stage Audit Framework
Automated Analysis
We use industry-leading tools like Slither and MythX to automatically detect common vulnerabilities such as reentrancy attacks, integer overflows, and gas optimization issues.
Manual Code Review
Our team of blockchain security experts perform line-by-line reviews to catch subtle logical errors or edge cases that automated tools may miss.
Formal Verification
For mission-critical contracts, we employ mathematical proofs to formally verify contract behavior against its intended logic.
Security by Design
Formal Verification
Mathematical proofs ensure contract behavior matches specified logic
Penetration Testing
Our security team simulates external attacks to find weaknesses
Regulatory Compliance
Contracts undergo legal review to ensure compliance with global AML/KYC standards

Benefits of Rigorous Auditing
Through our comprehensive audit process, we've achieved:
- 100% audit compliance with OpenZeppelin standards
- Avg. 98% reduction in contract vulnerabilities
- 99.99% system uptime for audited contracts
Final Thoughts
At walletr, we believe that trust in the blockchain ecosystem depends on rigorous security practices. Our multi-layered audit approach ensures that all smart contracts in our platform are not only functional but absolutely secure.
If you're a developer looking for secure contract deployment or a user seeking trusted DeFi platforms, remember that security should always be the top priority.
