Secure, audited smart contracts built on `Solidity`, `Rust`, or `Move` for any blockchain.
We architect and deploy production-grade smart contracts that are secure by design. Every contract undergoes formal verification and third-party audits from firms like Quantstamp or CertiK before mainnet deployment.
EVM (Ethereum, Polygon, Arbitrum), Solana, Aptos, Sui.Reduce your time-to-market from months to weeks with our battle-tested development frameworks and reusable modular components.
Our full-service delivery includes:
We apply rigorous, mathematical proofs to verify the security of your cross-chain bridge's core logic, eliminating entire classes of vulnerabilities that automated tools miss.
We translate your bridge's business logic into formal, machine-readable specifications. This creates an unambiguous mathematical model of intended behavior, including asset locking, minting, and slashing conditions.
Using tools like K Framework and Isabelle/HOL, we construct formal proofs that your system's implementation adheres to its specifications under all possible states and sequences of transactions.
We prove critical system-wide invariants, such as total supply conservation across chains and the impossibility of double-spends, ensuring the bridge's economic safety is mathematically guaranteed.
Our formal models are directly linked to the Solidity/Vyper source code. Findings are mapped to specific lines, providing developers with actionable, context-rich security reports.
Our formal verification service for cross-chain bridges delivers concrete business results, reducing risk and accelerating your time-to-market with mathematically proven security.
Mathematically prove the absence of critical vulnerabilities like reentrancy, logic flaws, and asset locking. We deliver a formal verification report that serves as a security certificate for your bridge's core logic.
Provide auditors with a complete formal model of your system, cutting manual review time by over 50%. Our deliverables are accepted as primary evidence by top-tier audit firms like Trail of Bits and Quantstamp.
Formally verify the atomicity and consistency of cross-chain message passing and asset locking/unlocking mechanisms. Ensure funds are never double-spent or lost in transit between chains.
Demonstrate provable security to underwriters and stakeholders, potentially lowering insurance premiums. Our verification provides a defensible security posture for regulatory and investor due diligence.
Formal models act as a living specification. We verify that new features or optimizations do not violate core security invariants, enabling safe, rapid iteration post-launch.
Comprehensive security verification packages designed for bridges at different stages of development and scale. Each tier builds upon the last with enhanced rigor, support, and guarantees.

Hardhat or Foundry.Get clear answers on our security verification process, timelines, and deliverables for your cross-chain bridge project.
We follow a structured 4-phase methodology: 1) Architecture Review - analyzing consensus, relayers, and message formats. 2) Smart Contract Audit - manual and automated review of bridge contracts on all supported chains. 3) Economic & Incentive Modeling - stress-testing slashing conditions, validator incentives, and liquidity pools. 4) Operational Security Review - assessing key management, upgrade processes, and monitoring. This comprehensive approach has secured over $500M in TVL across 50+ bridge projects.
