ENGINEERED FOR PRIVACY
Our Development Methodology
A systematic, security-first approach to building production-ready ZK-SNARK based cross-chain swaps. We deliver audited, high-performance systems, not just proofs of concept.
01
Privacy-First Architecture Design
We design the zero-knowledge circuit and smart contract architecture in tandem, ensuring privacy guarantees are foundational, not an afterthought. This includes threat modeling and defining precise privacy parameters before a single line of code is written.

Circuit Coverage
Phase 1

02
Circuit Development & Optimization
Expert implementation of ZK-SNARK circuits (Groth16, Plonk) using Circom or Halo2, focused on minimizing constraints and prover time. We deliver circuits that are efficient enough for real-time user interactions.

Frequently Asked Questions
Get clear, technical answers to common questions about our zero-knowledge cross-chain swap development service.
From initial architecture to mainnet deployment, a standard implementation takes 6-10 weeks. This includes 2 weeks for design & circuit specification, 3-4 weeks for core development and testing, and 1-2 weeks for security audits and final deployment. Complex multi-chain integrations or custom privacy features can extend this timeline.
