Expert security audits for blockchains
Quantstamp conducts smart contract, off-chain, networking, and front-end audits in order to enhance the security of your decentralized application. We are blockchain agnostic and have audited client systems on Ethereum, Hyperledger, Binance Chain, EOS, Polkadot, Cardano, AVA Labs and Corda. We also audit new blockchains and languages.
What we work on
We secure software incorporating blockchain technology including blockchain clients, DeFi and NFT applications, user wallets, and more.
We have audited numerous blockchain systems including Ethereum 2.0, Binance Smart Chain, Flow, Cardano, and Avalanche and have secured successful cutting-edge applications such as Maker, Compound, and NBA Top Shot. We audit software written in any programming language including new languages specifically written for blockchain applications such as Cadence from Flow.
Our process:
Step 1
You will have an initial meeting with a Quantstamp business lead and lead auditor.
Step 2
After receiving all necessary documentation and artifacts, we will assess the workload and provide a quote.
Step 3
Once accepted, 3 - 4 of our auditors will independently review your code and documentation. They will check whether the code conforms to the provided specification. They will also perform automated analyses on the code, run the test suite, and measure test coverage.
Step 4
Our auditors will then discuss any differences in their findings and come to consensus on solutions and recommendations.
Step 5
Our audit lead and business lead will communicate with your team if we need any further information.
