We architect and deploy custom smart contracts that power your core business logic, from tokenomics to complex DeFi protocols. Our code is built for mainnet from day one with security as the foundation.
CoinJoin Protocol Liquidity Engineering
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Security-First Development: Contracts are built on
Solidity 0.8+usingOpenZeppelinlibraries and undergo rigorous internal audits before delivery. - Gas Optimization: We specialize in writing efficient code to reduce user transaction costs by 15-40%.
- Full-Stack Integration: Contracts are delivered with comprehensive test suites, deployment scripts, and frontend SDKs for seamless integration.
We deliver battle-tested contracts that handle real value, ensuring your application's foundation is robust and secure.
Core Engineering Deliverables
We provide production-ready CoinJoin liquidity infrastructure, built for scale and security. Each deliverable is a fully integrated component, backed by verifiable performance metrics and security best practices.
Custom CoinJoin Coordinator
A high-throughput, non-custodial coordinator service with support for WabiSabi and Chaumian protocols. Features real-time fee management, participant scheduling, and automated UTXO selection for optimal privacy.
Liquidity Pool Integration Layer
Secure middleware connecting your CoinJoin protocol to major DEXs and CEXs for seamless liquidity sourcing and exit. Implements atomic swaps and cross-chain bridging for BTC, ETH, and stablecoins.
Anonymity Set Analytics Engine
Real-time dashboard and API for monitoring pool health, anonymity set size, and participant behavior. Provides actionable insights to optimize liquidity incentives and detect protocol-level threats.
Security & Audit Package
End-to-end security review including smart contract audits, coordinator penetration testing, and economic model analysis. All code follows OpenZeppelin standards and undergoes formal verification.
Business Outcomes: Reliable Privacy at Scale
Our CoinJoin protocol engineering delivers measurable infrastructure advantages for FinTechs and exchanges requiring institutional-grade privacy and compliance.
Institutional-Grade Uptime & Reliability
Deploy a non-custodial privacy layer with a 99.9% uptime SLA, ensuring your users' transactions are never delayed. Built on fault-tolerant, multi-region node architecture.
Regulatory-Compliant Anonymity Sets
Engineer liquidity pools that achieve mathematically provable anonymity (k-anonymity) while maintaining full audit trails for compliance (Travel Rule, AML). Integrates with Chainalysis and Elliptic.
Predictable, Optimized Fee Structure
Eliminate variable, unpredictable mixing costs. Our protocol engineering delivers fixed, sub-cent transaction fees with volume-based discounts, directly improving your unit economics.
Rapid Integration & Time-to-Market
Go live with a custom, white-labeled CoinJoin service in under 3 weeks. We provide full API documentation, SDKs, and dedicated technical support for your engineering team.
Scalable Throughput for High Volume
Process thousands of privacy transactions per second without degradation. Our architecture scales horizontally to support your user growth from launch to millions of active wallets.

Our Engineering Methodology
We engineer CoinJoin liquidity solutions with a focus on provable privacy, operational resilience, and seamless integration. Our process is designed to deliver enterprise-grade infrastructure that scales with your transaction volume.
High-Availability Coordinator Infrastructure
Deploy fault-tolerant coordinator nodes with multi-region failover, achieving 99.95% uptime SLA. We manage round scheduling, input registration, and signature aggregation to ensure continuous, non-custodial mixing operations.
Real-Time Liquidity Pool Engineering
Build automated, non-custodial liquidity pools that interface with coordinator outputs. We optimize for capital efficiency and minimize slippage, enabling high-volume exits into stablecoins or other assets without market impact.
Gas Optimization & Fee Management
Engineer batch processing and EIP-1559-aware fee strategies to reduce on-chain settlement costs by up to 40%. Our systems dynamically adjust to network conditions, protecting your operational margins.
Monitoring, Analytics & Compliance Feeds
Gain real-time visibility into mixing rounds, liquidity depth, and system health with dashboards and alerts. We provide structured data feeds for internal reporting and regulatory compliance (Travel Rule, AML).
Frequently Asked Questions
Get clear answers on how we build, secure, and scale private liquidity pools for your protocol.
A standard deployment for a custom CoinJoin liquidity pool takes 4-6 weeks from kickoff to mainnet launch. This includes 2 weeks for architecture and smart contract development, 1 week for internal testing and simulation, 1 week for a third-party security audit (optional but recommended), and 1-2 weeks for integration and final deployment. For integrating our pre-audited, modular liquidity components into an existing protocol, timelines can be as short as 2 weeks.
