Frontier Service
Smart contract audits test for known vulnerabilities. Formal verification proves mathematically that your contract cannot behave in ways you have not specified, even in scenarios you did not think of.
Formal verification uses machine-checkable mathematical proofs to prove that code satisfies its security specification, not just for known test cases, but for all possible inputs and edge cases. The ecosystem has matured rapidly: AI can now write and check proofs at scale, making formal verification practical for production smart contracts for the first time.
Ethereum’s core research is already building on it. Formal verification is being applied to STARKs, the ZK-EVM, Byzantine fault-tolerant consensus, and smart contract languages including Vyper. The frontier is moving fast. Security4Web3 brings this discipline to your contracts today.
Work is delivered through our internal consultancy team and a curated network of specialist partner firms, rigorously vetted for technical depth and professional integrity in the Web3 space.
Signal from the Frontier
“Bugs in computer code become more scary when you put cryptocurrency into immutable onchain smart contracts from which North Korea can automatically drain all your money with no recourse if there’s a bug in the code.”
The New Equilibrium
“AI gives you the ability to write large volumes of code at the cost of accuracy, and formal verification gives you back… accuracy (in fact, even more than you had before).”
Formal verification is gaining traction across Ethereum’s core research: STARKs, the ZK-EVM, consensus algorithms, and smart contract languages are all seeing verified implementations. Security4Web3 brings this frontier discipline to production-level contracts today.
Is It Right For You?
A standard audit finds known vulnerability patterns. Formal verification proves the absence of entire classes of bugs, including ones that have never been seen before. It is most valuable where the cost of a single logic error is irreversible.
Any protocol holding significant value on-chain. One logic flaw in an immutable contract has no recourse. Formal verification eliminates whole classes of risk before deployment.
Bridge contracts hold assets across two ecosystems simultaneously. Their complexity makes traditional testing insufficient, formal proofs cover every possible state transition.
Lending pools, AMMs, liquidation engines. Economic invariants, correct accounting, no path to insolvency, access control guarantees, can be proven mathematically, not just tested.
Regulators under MiCA, DORA, and VARA increasingly accept formal verification reports as documented evidence of security governance. Our reports are structured for this purpose.
