ZK-circuits are part of the Zero-Knowledge Proof process which allows one party to prove the truth of a statement to another party without disclosing any information about it. We use extractions from different zk-circuit Domain Specific Languages (DSLs) into Lean 4 proof assistant to verify zk-circuit properties formally.
EVM-based smart contract verification involves using formal methods to prove the correctness, security, and adherence to formal specifications of an EVM smart contract.

Starknet smart contract verification involves using formal methods to prove the correctness, security, and adherence to formal specifications of a Starknet smart contract.
RISC Zero is building the RISC Zero zero-knowledge virtual machine (zkVM) as a major step toward improving the security and trustworthiness of distributed applications.
Nethermind recently partnered with RISC Zero to develop tooling that formally verify their zk-circuit against the RISC-V semantics.

While this does not formally verify your implementation, it provides excellent testing coverage of the semantics of your protocol, which can be leveraged to find bugs in parts of your system.
This includes all the benefits of a pen and paper specification, but here we also encode these specifications into an interactive theorem prover (i.e., mechanizing). From this encoding, we verify high-level properties of the system and automatically extract a property tester.
We provide a range of full-stack smart contract formal verification services, formally verifying the implementation of your smart contracts against formal specifications we develop for you.
We offer automated formal verification tools for your new smart contract language. We can also develop encodings of the semantics of your new smart contract into an interactive theorem prover, along with various tools to expedite the process of formally verifying smart contracts using this encoding. Try out our ATP formal verification tool Horus.
We recognize that applications of formal verification within the web3 ecosystem are rapidly evolving, and we are interested in exploring any proposals you may have.
If you have formal verification needs outside of the Starknet ecosystem, get in touch and let's discuss what we can do for you.
