overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
From tokenization (
ERC-20,ERC-721,ERC-1155) to complex DeFi protocols, we deliver contracts that are gas-optimized, upgradeable, and built for long-term maintainability.
- Security Audits: Every contract undergoes internal review and can be prepared for third-party audits from firms like
CertiKorTrail of Bits. - Full Lifecycle Support: We handle development, testing (
Hardhat,Foundry), deployment, and post-launch monitoring. - Compliance Ready: Integrate features for regulatory requirements, including whitelisting, pause functions, and role-based access control.
