overview
CORE SERVICE

Smart Contract Development

Secure, gas-optimized smart contracts built to your exact specifications.

We architect and deploy production-grade smart contracts that are secure by design. Every contract undergoes a rigorous multi-stage audit process, including automated analysis with Slither and manual review by our in-house security team, before deployment to Mainnet.

  • Custom Logic: Build ERC-20, ERC-721, ERC-1155, and bespoke token standards.
  • DeFi Protocols: Develop automated market makers (AMMs), lending pools, and staking mechanisms.
  • Gas Optimization: Achieve up to 40% lower transaction costs through efficient bytecode and storage patterns.
  • Full Audit Trail: Receive comprehensive documentation and a verifiable security report.

From a 2-week MVP to a complex multi-chain system, we deliver contracts that are reliable, upgradeable, and ready for scale.

Frequently Asked Questions

Get clear answers on how we build secure, compliant, and automated onboarding systems for your Web3 platform.

A Legal Entity Onboarding System automates the collection, verification, and management of KYC/KYB documentation for corporate clients (e.g., VCs, DAOs, institutional funds) accessing your DeFi protocol, exchange, or tokenization platform. It's essential for compliance with global AML/CFT regulations, enabling you to serve institutional capital while managing risk. Without it, you face manual overhead, compliance gaps, and an inability to scale B2B offerings.
