Smart Contract Audit Cost Estimator
Estimate what your audit will cost across four delivery tracks, calibrated to real public pricing data, not a lead-capture form. Paste your code or enter your nSLOC.

What drives smart contract audit pricing
Two things dominate: size (normalized lines of code) and complexity (proxies and upgradeability, oracle dependencies, cross-chain messaging, ZK circuits, inline assembly). A 400-line ERC-20 and a 400-line bridge are not the same audit. This tool reads those complexity signals directly off your pasted code and places the project on the pricing curve, rather than asking you to guess.
The other levers are the delivery model (a solo auditor, a tier-1 firm, a public contest, or a layered program), the timeline (rush and emergency work carries a premium), and the chain (Solana/Rust and ZK/Cairo cost more than EVM because the specialist talent pool is smaller). Preparing well, clean documentation, a real test suite, and fixing automated scanner findings before the audit, reliably cuts the final cost.
