CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production from day one.
- Production-Ready Code: Contracts built with
Solidity 0.8+orVyper, following established standards likeERC-20,ERC-721, andERC-1155. - Comprehensive Audits: Every contract undergoes internal review and optional third-party audit coordination with firms like
CertiKorQuantstamp. - Gas Optimization: We write for efficiency, routinely achieving 20-40% lower gas costs versus unaudited implementations.
- Full Lifecycle Support: From initial spec to mainnet deployment and upgrade management via transparent
Proxypatterns.

TANGIBLE RESULTS
Business Outcomes of a Professional Migration
A strategic migration to a modern ZK proof system delivers measurable improvements in performance, cost, and security, directly impacting your bottom line and competitive edge.
01
Radically Reduced Transaction Costs
Migrate from gas-intensive proof systems to efficient ZK-Rollups (zkSync, StarkNet) or ZK-EVMs (Polygon zkEVM, Scroll). We deliver up to 90% lower gas fees for end-users, directly increasing protocol adoption and transaction volume.

Gas Cost Reduction
> 1000 TPS
Scalability Target
02
Enterprise-Grade Security Posture
Our migration process includes formal verification of new circuits and contracts, comprehensive audits, and integration with battle-tested libraries (e.g., Circom, Halo2). We ensure your new system inherits the cryptographic security guarantees of the underlying ZK protocol.

ZK Proof Migration FAQs
Get clear answers on timelines, costs, security, and process for migrating your protocol to a zero-knowledge proof system.
A standard ZK proof system migration takes 4-8 weeks from kickoff to mainnet deployment. This includes 1-2 weeks for architecture design and proof system selection (e.g., zk-SNARKs vs. zk-STARKs), 2-4 weeks for circuit development and integration, and 1-2 weeks for security audits and final testing. Complex protocols with custom logic or multi-chain requirements may extend this timeline. We provide a detailed project plan in the first week.
