Secure, audited smart contracts built for production and scale.
We architect and deploy custom, gas-optimized smart contracts on EVM and Solana that form the backbone of your application. Every contract follows OpenZeppelin standards and is designed for upgradeability and composability from day one.
Deliver a secure, audited MVP in as little as 2 weeks.
Our development lifecycle is built for security and speed:
Solidity 0.8+ or Rust logic.Ethereum, Polygon, Arbitrum, or Solana.We architect and deploy EVM-compatible privacy protocols with institutional-grade security, scalability, and compliance. Our engineering ensures robust anonymity sets, minimal trust assumptions, and seamless integration into your existing DeFi or payment stack.
A custom-built EVM mixer is a strategic asset. It delivers privacy, compliance, and operational advantages that generic solutions cannot match.
Custom logic enables features like gasless deposits, multi-asset batching, and predictable fee structures. This reduces friction, lowers costs for end-users, and drives higher transaction volume to your platform.
Own the protocol, its fee model, and its upgrade path. Capture value through custom fee structures and avoid reliance on third-party services, creating a new, sustainable revenue stream for your business.
We develop mixers with optimized smart contracts and circuit designs, reducing on-chain verification costs by up to 70% compared to generic implementations. This ensures long-term viability as network fees fluctuate.
Seamlessly embed privacy into your existing DeFi suite, NFT marketplace, or payment rail. Our custom mixers act as a native privacy layer, enhancing the utility and security of your entire product stack.
A transparent comparison of our structured development packages, from a secure foundation to a fully managed, production-ready privacy solution.

A systematic, security-first approach to delivering production-ready EVM-compatible mixer protocols, from initial architecture to mainnet deployment and ongoing support.
We begin with a zero-trust architecture review, identifying potential attack vectors (front-running, denial-of-service, privacy leaks) and designing robust mitigation strategies before a single line of code is written.
Implementation of custom zk-SNARKs or zk-STARKs circuits using Circom or Halo2 for the core mixing logic, ensuring cryptographic correctness and optimal proving performance.
Gas-optimized Solidity/Vyper contracts for deposit, proof verification, and withdrawal logic. We utilize established patterns from Tornado Cash and Aztec, hardened with formal verification where applicable.
Multi-layered audit process including internal review, automated analysis (Slither, MythX), and a final external audit by a top-tier firm like Trail of Bits or Quantstamp before any testnet deployment.
Development of a secure, intuitive user interface and a TypeScript SDK for seamless protocol integration into existing wallets, dApps, or custodial platforms.
Managed mainnet deployment with comprehensive monitoring dashboards for transaction volumes, anonymity set health, and security alerts, ensuring operational transparency and reliability.
A detailed breakdown of the technical, security, and business trade-offs between developing a custom, audited mixer from scratch versus deploying a forked, generic version.

Get clear answers on timelines, costs, security, and our development process for building a custom, compliant privacy protocol.
A standard, production-ready EVM-compatible mixer with core features (deposit/withdraw, anonymity set management, basic UI) takes 3-5 weeks from spec to mainnet deployment. Complex features like multi-asset support, zk-SNARK integration, or custom governance can extend this to 8-12 weeks. We provide a detailed sprint-by-sprint timeline after the initial technical scoping session.
