CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for speed, scale, and compliance.
- From Concept to Mainnet: Full-cycle development from architecture and
Hardhat/Foundrytesting to deployment and verification onEVM/Solana/Cosmoschains. - Security as Standard: Every contract undergoes internal audits, formal verification, and gas optimization before delivery.
- Compliance-Ready: Integrate on-chain access controls, upgradeability patterns, and regulatory hooks for real-world use.
Deliver a market-ready, audited smart contract system in as little as 4-6 weeks, with guaranteed correctness and comprehensive documentation.

What Our ZK Upgrade Audit Delivers
Our audit process is engineered to deliver specific, measurable security and compliance results for your zero-knowledge protocol upgrades, ensuring your project meets the highest standards for production deployment.
01
Comprehensive Security Analysis
In-depth review of ZK circuit logic, prover/verifier contracts, and upgrade mechanisms against 50+ vulnerability patterns, including soundness errors and front-running risks. We deliver a prioritized list of findings with exploit scenarios.

Why a Compliance-Focused Audit is Critical for Upgrades
Upgrading a ZK circuit or smart contract without a compliance lens introduces critical risks. Our audits ensure your upgrade not only functions correctly but also adheres to financial regulations, security standards, and on-chain governance requirements from day one.
03
Ensure Protocol & Economic Consistency
We validate that tokenomics, fee structures, and incentive mechanisms in the upgrade remain consistent with the original white paper and community expectations to maintain trust.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your protocol.
We architect and deploy custom smart contracts that form the secure, immutable backbone of your application. Our development process is built on security-first principles, utilizing battle-tested libraries like OpenZeppelin and rigorous testing frameworks to mitigate risk before mainnet deployment.
From tokenomics to governance, we translate your business logic into robust, gas-optimized code.
- End-to-End Development: Full lifecycle support from architecture and
Solidity/Rustcoding to deployment and verification onEVM,Solana, orStarknet. - Security & Audits: Multi-stage review process, including internal audits and coordination with top firms like
CertiKorTrail of Bits. - Gas Optimization: Expert tuning to reduce transaction costs by up to 40%, directly impacting user adoption and protocol economics.
- Integration Ready: Contracts are built with clear interfaces for seamless connection to frontends, oracles, and cross-chain bridges.

Frequently Asked Questions
Get clear answers on our specialized audit process, timeline, and security guarantees for zero-knowledge protocol upgrades.
We employ a three-phase methodology: 1) Architectural Review: Analyze the upgrade's impact on the existing system's security model and compliance posture. 2) Targeted Code Audit: Manual and automated review focusing on the new ZK circuits, verifier logic, and integration points, using tools like Circomspect and custom fuzzing. 3) Compliance Verification: Formal verification of cryptographic soundness and adherence to standards like NIST FIPS 140-3 where applicable. This process has secured over $500M in TVL across 50+ protocol upgrades.
