CORE SERVICES

Smart Contract Development

Secure, audited smart contracts built for production by Web3-native engineers.

We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our development process is built for security and speed, delivering a production-ready MVP in 2-3 weeks.

  • Security-First Development: Code written in Solidity 0.8+ or Rust using OpenZeppelin patterns and internal audit checklists.
  • Gas Optimization: Every contract is optimized for up to 40% lower transaction costs.
  • Full Testing Suite: Comprehensive unit and integration tests with Hardhat or Anchor for 95%+ coverage.

We don't just write code; we deliver battle-tested infrastructure that handles real value.

Our team handles the entire lifecycle:

  • Design & Specification: Collaborative sessions to map requirements to secure on-chain logic.
  • Development & Auditing: Iterative builds with peer reviews and optional third-party audit coordination.
  • Deployment & Monitoring: Mainnet deployment with tools for real-time monitoring and incident response.

END-TO-END SECURITY

Our Development & Audit Process

A rigorous, multi-layered approach designed to deliver production-ready, secure ZK-Rollup vaults. We combine battle-tested development practices with exhaustive security audits to ensure your privacy solution is robust from day one.

01

Architecture & Design Review

We start with a collaborative deep-dive to architect your vault's privacy model, data flow, and integration points. This ensures the system design is sound, scalable, and aligns with your specific use case before a single line of code is written.

ZK-Rollup Privacy Vaults

Frequently Asked Questions

Get clear answers on development timelines, security, costs, and our process for building custom ZK-Rollup privacy vaults.

From initial design to mainnet deployment, a standard ZK-Rollup vault with core privacy features takes 6-10 weeks. This includes architecture, smart contract development, circuit design (e.g., with Circom or Halo2), integration with a rollup stack (like StarkEx or zkSync), and security audits. Complex requirements like multi-asset support or custom proving schemes can extend the timeline to 12-16 weeks.
