CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
From token launches to complex DeFi protocols, we deliver contracts you can stake your business on.
- Security Audits: Every contract undergoes rigorous review using
SlitherandMythX, with optional third-party audits fromOpenZeppelinorCertiK. - Full-Stack Integration: Seamless connection to your frontend via
ethers.js/web3.jsor@solana/web3.js, including event listeners and state management. - Compliance Ready: Built-in support for
ERC-20,ERC-721,ERC-1155, and custom standards with upgradeability viaTransparentorUUPSproxies.
Deliverables in 4-6 weeks: Audited source code, comprehensive documentation, deployment scripts, and a dedicated technical point of contact for ongoing support.
