Security Audits
Runtime Verification audits are not just a checkmark. They are an uncompromising end-to-end review, and a mark of a security conscious team.
Audits by Formal Methods Experts
Request an AuditInvariant-First Analysis
Before touching the code, we define the invariants: the properties that must always hold. This ensures we know exactly what correct behavior looks like from the start.
A Barrage of Rigorous Tools
We verify invariants with symbolic execution, fuzzing, and model checking, including our partner Almanax, covering attack surfaces traditional audits miss.
Reports That Go Beyond Bugs
Our reports include documented invariants, system descriptions, and architecture notes: lasting documentation your team can reference long after the audit.
OpSec Best Practices
Beyond bugs, we recommend operational security improvements (key management, deployment procedures, access controls), building security into every layer.
The most complete security audit in the industry.

Work We're Proud Of
From blockchain launches to aerospace systems: a sample of what we've secured.
Monad: Pre-Launch Security Clearance
Full pre-launch review of the Monad blockchain: architecture hardening, fuzzing harness improvements, and last-mile production checks before one of the most anticipated chain launches in recent memory.

NASA: Mission-Critical Formal Verification
Three consecutive NASA SBIR grants. When the most rigorous engineering organization on Earth needs formal methods expertise, they call Runtime Verification.

Espresso Systems: High-Value Staking Contracts
A precision audit of Espresso's Solidity staking contracts, protecting significant on-chain value with the same depth of rigor we bring to full-scale protocol reviews.

Soroban VM: Smart Contract Runtime Security
Two months inside Stellar's Rust-based smart contract execution environment, covering architecture review, deep fuzzing, and line-by-line analysis of every unsafe code block before mainnet launch.

WASMI: Interpreter-Level Hardening
Every system built on a WASM interpreter inherits its bugs. Our weeks-long review of WASMI uncovered crash vectors and execution inconsistencies that would have silently propagated to every application above it.

Solana Foundation: Token Standard Verification
Formal verification and audit of Solana's p-token and token wrap programs, foundational standards that underpin billions in on-chain value across one of the fastest blockchains in the world.

Why Runtime Verification
Formal Methods: the Security Edge in the Age of AI
As AI generates more of the code, the question isn't just whether it works, but whether it's correct. Formal methods define the standard. Everything else gets checked against it.
- Auditing since 2017
- Nearly a decade of reviews across any language: Rust, Go, C++, Solidity, JavaScript, and more. Our formal specification approach means the language is never the barrier; understanding the system is.
- Trusted by Leaders Across Industries
- DARPA, NASA, Boeing, the Ethereum Foundation, Solana, and Stellar have trusted us with critical systems, spanning aerospace, defense, and frontier technology.
- Open-Source by Conviction
- We build in the open. We maintain the K Framework (a formal methods platform used by researchers worldwide) and contribute to the broader security ecosystem.
- AI-Ready Security Specifications
- The specs and invariants we produce are machine-readable artifacts. We help teams encode security guarantees that AI agents can enforce throughout the development lifecycle.
"We see a worrisome trend in the industry where timelines are a race to the bottom, and we are not willing to compromise. A Runtime Verification audit report is a stamp of approval from our team. It's also a signal to our client's users and community that security is a priority, not an afterthought."
