Runtime Verification

High-assurance cybersecurity consulting for critical systems. Rooted in formal methods, our engineers work closely with teams developing software that cannot fail.

Runtime Verification provides advanced security and quality assurance services for blockchain systems and mission-critical software. We specialize in smart contract audits, protocol and infrastructure reviews, fuzz testing, and formal verification, helping teams build systems that are correct, secure, and resilient.

Our approach goes beyond traditional audits. Every engagement begins with a design review where we analyze system architecture, identify potential failure modes, and define key invariants - properties that must always hold true. These invariants guide our line-by-line code review, fuzzing campaigns, and AI-assisted analysis to uncover both implementation bugs and deeper logic flaws.

We work across the full stack, including:

Smart Contracts (Solidity, Rust/Soroban, Solana programs)
Blockchain Infrastructure (validators, consensus components, execution layers)
Off-Chain Systems & Integrations

In addition to manual review, we deliver practical security artifacts such as property-based tests, fuzzing harnesses, and specifications that teams can reuse to validate future changes and integrate into CI pipelines.

Runtime Verification is also a leader in formal methods, developing tools such as Kontrol (for EVM), Komet (for Soroban), and KMIR (for Solana), enabling rigorous reasoning about system correctness beyond conventional testing.

Since 2017, we have worked with leading organizations across Web3 and enterprise systems including Ethereum Foundation, Optimism, Solana Foundation, Stellar Development Foundation, and Monad. We focus on long-term partnerships, helping teams continuously improve security as their systems evolve.

Use Cases

Smart Contract & Infrastructure Security Audits

We audit smart contracts and blockchain infrastructure that integrate with stablecoins, including DeFi protocols, payment systems, validators, and execution layers. Our approach combines design review with deep, line-by-line code analysis to identify vulnerabilities, logic flaws, and unsafe assumptions. We focus on correctness of financial flows, access control, and system interactions to support secure, reliable, and production-ready integrations.

Design Review & Formal Modeling

We engage early in the development lifecycle to analyze system architecture and define formal or informal specifications (“invariants”) that describe correct behavior. This process identifies high-level design flaws before they reach production and provides a foundation for testing, audits, and ongoing development. These specifications can also guide AI-assisted development, helping ensure new features and integrations with stablecoins remain within safe and intended constraints.

Fuzz Testing & Formal Verification

We use advanced fuzzing and formal verification techniques to uncover edge cases and prove correctness of critical system components. Fuzzing simulates adversarial inputs to identify crashes and unexpected behaviors, while formal verification ensures key properties - such as accounting consistency and access control - hold under all possible conditions. This combination provides a high level of assurance for systems managing stablecoin flows.

Operational Security & System Hardening

We review operational and administrative controls around stablecoin-integrated systems, including key management, upgrade mechanisms, timelocks, and emergency procedures. Our goal is to reduce real-world risk by helping ensure that sensitive operations are properly controlled, auditable, and resilient to misuse or compromise. This includes evaluating both onchain controls and off-chain operational processes.

Risk & Compliance-Oriented Consulting

We help teams identify and mitigate financial and operational risks associated with stablecoin integrations. This includes reviewing treasury flows, asset custody assumptions, and failure modes that could impact funds or system stability. Our assessments support organizations operating in regulated or high-stakes environments by providing clearer visibility into risks and practical recommendations for improving security posture.
