Pruvendo provides cybersecurity solutions based on deductive formal verification technology to ensure the mathematical correctness and security of blockchain smart contracts. The company specializes in secure smart contract development, formal specification, and comprehensive audits for systems built on Solidity and Rust, supporting EVM, TVM, and MultiversX VM ecosystems. Their proprietary Coq-embedded language, Ursus, enables rigorous mathematical proof of system properties, distinguishing their services from traditional audit approaches.

Problem
Smart contracts are vulnerable to critical exploits and bugs that traditional auditing methods often miss, leading to significant financial losses and security breaches. Standard testing and code review approaches cannot provide mathematical certainty about a system's correctness, leaving complex multi-contract and asynchronous systems exposed to unpredictable behavior and attack vectors.
Solution
Pruvendo applies deductive formal verification technology to make critical blockchain systems measurably credible and mathematically provable. The company offers secure smart contract development, comprehensive audits, formal specification design, and full deductive formal verification services for both simple and complex multi-contract asynchronous systems. Their approach involves analyzing program architecture, constructing call graphs, identifying potential security flaws, and developing both informal and formal specifications before using their proprietary Coq-embedded language, Ursus, to mathematically prove system properties. This methodology has successfully uncovered critical exploits overlooked by conventional audits and delivered systems that are considered 100% predictable.
Target Audience
Primary customers are blockchain projects, decentralized application developers, and enterprises building critical smart contract systems that require the highest level of security assurance, particularly those operating in DeFi, GameFi, and multi-signature wallet environments.
