overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production at scale.

We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our contracts are built for high-volume, high-value applications with a focus on gas efficiency and security-first design.

  • Full Development Lifecycle: From specification and Solidity/Rust coding to deployment and on-chain verification.
  • Security by Default: Adherence to OpenZeppelin standards, formal verification, and integration with leading audit firms.
  • Production-Ready: Includes comprehensive testing suites, upgradeability patterns (TransparentProxy, UUPS), and monitoring dashboards.

We deliver contracts you can trust, reducing time-to-audit by 40% and mitigating critical vulnerabilities before mainnet launch.

MATHEMATICAL CERTAINTY FOR ZK CIRCUITS

Our Formal Verification Capabilities

We apply rigorous formal methods to mathematically prove the correctness of your ZK-Rollup circuits, eliminating the risk of logic bugs and ensuring your protocol operates exactly as specified.

01

Circuit Logic Verification

We formally verify the logical correctness of your custom ZK circuits (R1CS, Plonkish) against your protocol's specification, guaranteeing no arithmetic overflows, underflows, or incorrect constraints exist.

100%
Logic Coverage
Zero Bugs

02

Security Property Proofs

We define and prove critical security invariants—like soundness, completeness, and non-malleability—using theorem provers (Coq, Lean) to ensure your rollup's state transitions are cryptographically secure.

BEYOND AUDITS

Why Mathematically Verify Your ZK Circuits

Traditional audits find bugs; formal verification mathematically proves your circuit's logic is correct. For ZK-Rollups securing billions in assets, this is the ultimate guarantee of security and reliability.

01

Eliminate Logical Vulnerabilities

We use formal methods to prove your circuit's arithmetic constraints and business logic are mathematically sound, eliminating entire classes of bugs that manual audits can miss.

Ensure Protocol Correctness

Formal verification guarantees your ZK-Rollup's state transition logic—deposits, withdrawals, and transaction execution—adheres precisely to your protocol specification.

Formal Verification for ZK-Rollups: FAQs

Get clear, technical answers to the most common questions CTOs and engineering leads ask about securing their ZK-Rollup circuits with formal verification.

A standard engagement for a core ZK circuit (e.g., a state transition or Merkle tree) takes 4-6 weeks from kickoff to final report. Complex, multi-circuit systems (like a full zkEVM) can take 8-12 weeks. The timeline includes specification formalization, theorem proving, and comprehensive documentation.
