Smart Contract Audit Playbook for Tier-1 Security Review

Frequently Asked Questions

01.How much does a Tier-1 smart contract audit cost?

A Tier-1 smart contract audit typically costs between fifteen thousand and eighty thousand US dollars, depending on codebase size, complexity, and the number of protocol interactions involved. Some top-tier firms charge above that range for very large codebases or formal verification work. The cost of an audit is a fraction of the cost of a successful exploit.

02.How long does a Tier-1 audit take?

Most Tier-1 audits run four to eight weeks from kickoff to final report. This window covers initial scoping, active review, remediation, and a re-audit cycle. Projects with incomplete documentation or untested code often extend this timeline. Strong preparation can compress the active review phase by one to two weeks.

03.Can a smart contract audit guarantee zero vulnerabilities?

No audit firm can guarantee zero vulnerabilities. A Tier-1 audit significantly reduces risk by identifying known vulnerability classes, protocol-level logic errors, and compliance gaps. The goal is a defensible, documented security posture, not a perfect one. Post-audit bug bounty programs complement the audit by providing ongoing community review.

04.What documentation should founders prepare before an audit?

Prepare a technical specification covering all protocol flows, a threat model, a full test suite with coverage reports, a changelog of recent changes, and a list of third-party integrations. Auditors who receive complete documentation typically deliver faster, deeper findings.
