CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 specialists for your token, DeFi, or NFT project.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance. - DeFi Protocols: Automated Market Makers (AMMs), liquidity pools, staking, and yield strategies.
- Enterprise Logic: Multi-signature wallets, access control, and custom on-chain business rules.
- Full Audit Support: Code is structured for seamless review by leading security firms like CertiK or Quantstamp.
We deliver battle-tested contracts with 99.9% uptime SLAs, reducing your time-to-market from months to as little as 2 weeks for an MVP. Security isn't an afterthought—it's the foundation of every line of

Frequently Asked Questions
Get clear answers about our security audit process, timeline, and what to expect when securing your smart contract wallet.
We employ a hybrid methodology combining automated analysis with deep manual review. Our process includes: 1) Static Analysis using Slither and custom tools to detect common vulnerabilities. 2) Manual Code Review by senior auditors focusing on wallet-specific logic (e.g., multi-sig, session keys, social recovery). 3) Formal Verification for critical state transitions. 4) Integration Testing against common attack vectors like front-running and reentrancy. This multi-layered approach has secured over $500M in TVL across 50+ wallet projects.
