What Does a Smart Contract Audit Cost?
2026 pricing guide for smart contract audits — what to expect, what affects cost, and how to get the most value from your security budget.
What Does a Smart Contract Audit Cost?
The most common question we hear from founders: "How much should I budget for an audit?" The honest answer is it depends — but here are real numbers from the market.
Pricing Ranges (2026)
| Complexity | Typical Cost | Timeline | Example |
|---|---|---|---|
| Simple token/NFT | $5K - $20K | 1-2 weeks | ERC-20, ERC-721 with standard logic |
| DeFi protocol (medium) | $20K - $80K | 3-6 weeks | Lending, staking, vaults |
| Complex DeFi / Bridge | $80K - $200K | 6-10 weeks | Cross-chain bridges, novel AMM designs |
| L2/Infrastructure | $150K - $500K+ | 8-16 weeks | Rollup contracts, consensus mechanisms |
These ranges reflect private audits from established firms. Competitive audit platforms can be 30-50% less.
What Affects Price
- Lines of code — Most firms price per LOC or per auditor-day. More code = more time = higher cost.
- Complexity of logic — Novel math (custom bonding curves, new AMM invariants) takes longer to review than standard patterns.
- Chain — Solana and Move (Aptos/Sui) audits cost more due to fewer qualified auditors. EVM has the most competition and lowest prices.
- Timeline — Rush jobs command a 1.5-2x premium. Plan ahead and book 6-8 weeks in advance.
- Firm tier — Boutique firms ($200-400/hr) vs. top-tier firms ($400-800/hr). Both can deliver quality; it depends on your risk profile.
How to Save Money
- Run free tools first — Slither, Echidna, and Aderyn catch common bugs before auditors see them. Fewer findings = faster audit = lower cost.
- Clean, documented code audits faster — Auditors bill for time spent understanding your code. Good docs and clear naming save real money.
- Use competitive audit platforms — Code4rena, Sherlock, and Cantina run crowdsourced audits for 30-50% less than private firms.
- Consider a tiered approach — Competitive audit first for broad coverage, then a private audit on critical paths. Best of both worlds.
- Fix what you can before the audit — Every bug you find yourself is a bug you don't pay an auditor to document.
Red Flags in Pricing
- Under $5K for anything non-trivial — You get what you pay for. A cheap audit that misses a critical bug costs infinitely more than a proper one.
- No fixed quote — Reputable firms scope before pricing. If they can't give you a number after reviewing your codebase, they're either disorganized or planning to upsell.
- Won't share public audit reports — Low transparency is a red flag. The best firms are proud of their work and publish results.
- "Guaranteed secure" promises — No audit guarantees safety. Anyone who says otherwise is selling you something, not security.
