Understanding Smart Contract Security Audits
Smart contract security audits are essential for identifying vulnerabilities and ensuring the integrity of blockchain-based applications. Our comprehensive audit program covers multiple blockchain ecosystems, providing tailored solutions for each platform's unique requirements.
Token Security Audit Framework
We conduct in-depth examinations of token contracts with the following focus areas:
| Audit Category | Key Focus Areas |
|---|---|
| Overflow & Underflow | Integer operation vulnerabilities |
| Race Conditions | Transaction ordering risks |
| Permission Management | Access control and authority levels |
| Security Design | External module integration and compiler safety |
| Denial of Service | System resilience against attacks |
| Gas Optimization | Efficiency improvements |
| Design Logic | Contract flow and business logic |
Our token audits specifically examine:
- Fallback function implementation
- Hard-coded address security
- Function return value handling
- Low-level call safety

DeFi Security Audit Components
Decentralized Finance protocols require specialized attention due to their complex interactions:
| Vulnerability Type | DeFi-Specific Risks |
|---|---|
| Flashloan Attacks | Price oracle manipulation |
| Reentrancy Attacks | Fund drainage vectors |
| External Calls | Unsafe contract interactions |
| Block Data Dependence | Miner manipulation risks |
Key audit points include:
- Proper tx.origin validation
- Secure external call patterns
- Accurate arithmetic operations
- Variable scope management
Move Language Security (Aptos/Sui)
For Move-based contracts, we emphasize:
| Security Aspect | Move-Specific Considerations |
|---|---|
| Capability Model | Proper privilege management |
| Resource Handling | Secure asset movement |
| Visibility Control | Function exposure analysis |
| External Calls | Safe interaction patterns |
Solana Program Security
Solana's unique architecture requires specialized audit approaches:
| Risk Category | Solana-Specific Concerns |
|---|---|
| Account Forging | Fake account creation |
| CPI Safety | Cross-program invocation |
| Rent Exemption | Storage payment issues |
| Anchor Framework | Common implementation mistakes |
EOSIO Contract Audits
For EOS-based applications, we examine:
| Audit Focus | EOS-Specific Items |
|---|---|
| Rollback Protection | Transaction reversal risks |
| RAM Management | Resource allocation safety |
| Random Number Generation | Predictability analysis |
| Authority Model | Proper permission structuring |

Frequently Asked Questions
Q: How long does a typical smart contract audit take?
A: Audit duration depends on contract complexity, ranging from 1-4 weeks for most projects.
Q: What's the difference between token and DeFi audits?
A: DeFi audits focus more on protocol interactions and financial mechanisms, while token audits concentrate on asset management and transfer safety.
Q: Can audits prevent all vulnerabilities?
A: While audits significantly reduce risks, no audit can guarantee 100% security. Continuous monitoring is recommended.
Q: How often should contracts be re-audited?
A: After major updates or at least annually for active projects.
Q: Do you audit NFT contracts?
A: Yes, our service covers all smart contract types including NFT and marketplace contracts.
Q: What post-audit support do you provide?
A: We offer remediation guidance and verification of fixes implemented.
