CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built for production by Web3-native engineers.
- Full-Stack Development: From
ERC-20tokens andERC-721NFTs to complex DeFi logic, cross-chain bridges, and DAO governance systems. - Security-First Approach: Code reviews, integration of
OpenZeppelinlibraries, and preparation for third-party audits by firms like CertiK or Quantstamp. - Production-Ready Delivery: We provide comprehensive documentation, deployment scripts, and a 2-week MVP delivery for validated concepts.
Move from concept to a live, auditable contract on
Ethereum,Polygon,Solana, or other L1/L2 networks in weeks, not months.

PROVEN PROCESS
Our ZKP Migration Methodology
A structured, security-first approach to migrating your zero-knowledge applications across chains, minimizing risk and maximizing performance.
01
Architecture & Feasibility Audit
We conduct a deep technical assessment of your existing ZKP circuits and smart contracts. We identify cross-chain compatibility issues, gas inefficiencies, and security vulnerabilities before migration begins.
48-72 hours
Initial Assessment

Code Coverage
02
Circuit Porting & Optimization
Our team ports your ZK-SNARK/STARK circuits to the target chain's proving system (e.g., Plonk, Groth16, Halo2). We optimize for prover speed and verifier gas costs, often achieving 30-50% efficiency gains.

PROVEN METHODOLOGY
How We Deliver Your Migration
Our structured, security-first approach ensures your ZKP migration is executed with precision, minimal risk, and zero downtime. We deliver a production-ready system, not just code.
01
Architecture & Strategy Blueprint
We begin with a comprehensive audit of your current system and design a detailed migration blueprint. This includes selecting the optimal target chain (zkSync, Starknet, Polygon zkEVM), defining the ZKP circuit architecture, and planning for gas optimization and data availability.

Technical & Commercial Questions
ZKP Migration FAQs
Answers to the most common questions CTOs and technical leads ask when evaluating a ZKP migration partner.
A standard migration from a non-ZKP system (like a basic EVM rollup) to a ZK-rollup framework (zkSync, StarkNet, Polygon zkEVM) typically takes 3-6 weeks. This includes architecture design, circuit development, proof system integration, and on-chain deployment. Complex protocols with custom logic or multi-chain state may extend to 8-10 weeks. We provide a detailed project plan with weekly milestones during scoping.
