BUILT FOR ENTERPRISE
Core Implementation Capabilities
We deliver production-ready, audited CoinJoin infrastructure that integrates seamlessly into your existing payment stack, ensuring compliance, scalability, and user privacy from day one.
01
Custom CoinJoin Coordinator
We build and deploy a private, high-availability coordinator service using Zero-Knowledge proofs (zk-SNARKs) for transaction validation. This ensures your platform controls the mixing process, maintains audit trails for compliance, and prevents deanonymization attacks.

Coordinator Capacity
< 100ms
Round Latency
02
Regulatory-Compliant Design
Implementation follows FATF Travel Rule protocols (IVMS101) and integrates with Chainalysis or Elliptic for on-chain monitoring. We architect the system to provide selective disclosure proofs for regulators while preserving default user privacy, a critical requirement for licensed VASPs.

03
Wallet SDK & API Integration
We provide a lightweight SDK for web and mobile apps that handles CoinJoin participation, UTXO management, and fee optimization. Includes a REST API for backend services to initiate mixes, check status, and generate compliance reports, enabling integration in under two weeks.

Anonymity Set Optimization
Our algorithms dynamically adjust mix parameters—like round size and denomination—based on network liquidity and participant volume. This maximizes the effective anonymity set for your users, providing stronger privacy guarantees than fixed-parameter systems.

Multi-Asset & Cross-Chain Support
Implement CoinJoin for Bitcoin, Litecoin, and Bitcoin-based assets (e.g., Liquid Network). We design the architecture to be chain-agnostic, allowing future expansion to Ethereum (using Tornado Cash-like circuits) or other UTXO chains without a full rewrite.

Frequently Asked Questions
Get clear answers on our process, security, and outcomes for integrating privacy-enhancing CoinJoin technology into your payment platform.
A standard implementation for a payment processor takes 4-6 weeks from kickoff to production deployment. This includes architecture design, smart contract development, integration with your existing payment rails, and a full security audit. Complex integrations with custom UTXO management or multi-chain support may extend to 8-10 weeks. We provide a detailed project plan with weekly milestones.
