CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your dApp.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155contracts with advanced features like vesting, staking, and governance. - DeFi & DEX: Automated Market Makers (AMMs), liquidity pools, yield strategies, and cross-chain bridges.
- Security First: Every contract undergoes internal review and is structured for seamless third-party audits from firms like
CertiKorTrail of Bits.
Reduce your time-to-market from months to weeks. We provide a clear development roadmap, from initial spec to mainnet deployment on
Ethereum,Polygon,Arbitrum, or other EVM-compatible chains.

Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts.
We architect and deploy custom smart contracts that form the foundation of your dApp. Our development process is built for security and scalability from day one.
- Security-First Development: Code written in
Solidity 0.8+usingOpenZeppelinlibraries, with formal verification and multi-stage audits. - Gas Optimization: Contracts are engineered for up to 40% lower gas costs through efficient storage patterns and opcode-level tuning.
- Full-Spectrum Support: From
ERC-20tokens andERC-721NFTs to complex DeFi primitives, cross-chain bridges, and DAO governance systems.
We deliver battle-tested contracts with a documented security posture, ready for mainnet deployment in as little as 2-4 weeks.
Our post-deployment services include monitoring, upgrade management, and incident response, ensuring your protocol's long-term integrity and performance.

Frequently Asked Questions
Get clear answers on timelines, costs, security, and implementation for your private credential system.
A standard deployment, from design to mainnet launch, takes 4-6 weeks. This includes 1 week for architecture and circuit design, 2-3 weeks for smart contract and ZK circuit development, and 1-2 weeks for integration, testing, and audit preparation. Complex integrations with existing identity systems or custom privacy logic can extend this timeline.
