Hybrid CeFi/DeFi Stablecoin Gateway Development

We build secure, compliant gateway infrastructure that connects traditional banking and payment rails (CeFi) with decentralized finance (DeFi) protocols for seamless stablecoin minting, redemption, and liquidity management.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that power your core business logic—from token economies to DeFi protocols. Our development process is built for security and speed, delivering audit-ready code in 2-4 weeks.

We don't just write code; we engineer systems that are secure by default and ready for mainnet.

  • Full-Stack Development: End-to-end solutions for ERC-20, ERC-721, ERC-1155, and custom standards.
  • Security-First: Built with OpenZeppelin libraries and formal verification patterns.
  • Gas Optimization: Contracts engineered for up to 40% lower execution costs.
  • Compliance Ready: Modular design for regulatory features like transfer pausing and allowlists.

Hybrid Gateway Development: Key Questions

Answers to the most common technical and commercial questions about building a secure, scalable hybrid stablecoin gateway.

We follow a structured 4-phase delivery model. Discovery & Architecture (1 week) defines requirements and tech stack. Core Development (2-3 weeks) builds the gateway smart contracts and backend APIs. Security & Testing (1 week) includes internal audits and integration testing. Deployment & Handoff (1 week) finalizes mainnet deployment and documentation. Typical time-to-production is 5-6 weeks for a standard gateway with support for 2-3 blockchains and major stablecoins.
