Certora Prover is a formal verification tool for smart contracts. It mathematically analyzes contract bytecode against user-defined rules to determine whether specified code properties hold under any possible contract state or execution path. Developers write rules, called specifications, in the Certora Verification Language (CVL), a syntax similar to Solidity used to describe expected contract behavior. Prover compares these rules against the compiled contract bytecode to identify scenarios that could violate the specified properties, rather than sampling execution paths as fuzz testing does. When a rule violation is found, Prover generates a concrete call trace showing the sequence of steps leading to the issue. Results, including rule pass/fail status and call traces, are viewed on the Prover Dashboard, which can be shared with team members. Prover can be integrated into a development pipeline to run on every code commit, allowing continuous verification as code changes. It is used by DeFi protocol teams, including Aave, Compound, and Balancer, referenced as users on the page. The product is offered under free, premium, and enterprise plans, with differences in runtime limits, team size, support level, and additional services such as rule writing and audit retainers.</description> <parameter name="summary">Formal verification tool that mathematically proves smart contract code properties
