How much does a smart contract audit cost?

Smart contract audits start at $500 for a Quick Scan (single contract, up to 500 lines). Full reviews are $1,500, and protocol-level audits range from $3,000-$5,000. We also offer a pay-per-finding model: $300 base fee plus per-vulnerability bonus (Critical $500, High $300, Medium $150, Low $50).

What is the pay-per-finding model?

Pay-per-finding means you pay a $300 base fee for the audit, then a bonus for each vulnerability found based on severity: Critical $500, High $300, Medium $150, Low $50. You only pay more if we actually find bugs — aligning our incentives with yours.

What smart contract languages do you support?

We audit Solidity (Ethereum, BSC, Polygon, Arbitrum, Optimism), Rust (Solana, Near, Cosmos), and Move (Aptos, Sui). We cover DeFi protocols, NFT contracts, DAOs, token launches, and cross-chain bridges.

Do you also offer web2 penetration testing?

Yes. We offer full-stack web2 penetration testing including web applications (OWASP Top 10), API security, cloud infrastructure (AWS/GCP/Azure), and network testing. Packages start at $500 USDT with 77+ offensive tools and ~3 day delivery.
