How much does a smart contract audit cost?
The cost of a smart contract audit typically ranges from $3,000 to $100,000+, depending on the size, complexity, and risk profile of the contract. Simple smart contracts or NFT projects may require lower-cost audits, while complex DeFi protocols, cross-chain bridges, or multi-contract systems demand extensive manual review, automated testing, and multiple audit rounds — significantly increasing costs.
