Quantstamp (QSP) Quantstamp is the first scalable security-audit protocol designed to find vulnerabilities in Ethereum smart contracts. The Quantstamp protocol solves the smart contract security problem by creating a scalable and cost-effective system to audit all smart contracts on the Ethereum network. Over time, Quantstamp expects every Ethereum smart contract to use the Quantstamp protocol to perform security audits, as security is essential. The Quantstamp protocol relies on a distributed network of participants to mitigate the effects of bad actors, creating the required computing power to provide governance. Each participant will use the Quantstamp Protocol Tokens (QSP) to pay for, receive, or improve upon verification services. The minimal withdrawal is 20 000 000 QSP.
