CORE INFRASTRUCTURE
Smart Contract Development
Secure, gas-optimized smart contracts built for production from day one.
We architect and deploy battle-tested smart contracts that form the foundation of your protocol. Every line of code is written with security, efficiency, and maintainability as first principles, using Solidity 0.8+ and OpenZeppelin libraries.
Deliver a production-ready, audited contract suite in 2-4 weeks, not months.
- Security-First Development: Comprehensive unit/integration testing, formal verification with tools like
SlitherandMythX, and preparation for third-party audits. - Gas Optimization: Every function is profiled and optimized to reduce user transaction costs by 15-40%.
- Upgradeability & Management: Implement secure upgrade patterns (
TransparentProxy,UUPS) and provide tools for multi-signature administration and pausing mechanisms.

Frequently Asked Questions
Get clear answers on our development process, security, and timelines for implementing a custom privacy identity layer.
Our process follows a structured 4-phase approach: 1. Discovery & Architecture (1-2 weeks): We analyze your use case and design the identity schema and privacy requirements. 2. Core Development (3-5 weeks): We build the custom circuits (using Circom or Halo2), smart contracts, and off-chain prover/verifier logic. 3. Integration & Testing (2-3 weeks): We integrate with your dApp frontend, conduct internal audits, and perform rigorous testing on testnets. 4. Deployment & Support (1 week): We deploy to mainnet and provide onboarding. We provide weekly sprint reviews and use Jira/Linear for transparent task tracking.
