SECURE BY DESIGN
Smart Contract Development
Production-grade smart contracts built for security, gas efficiency, and real-world use.
From concept to mainnet, we deliver battle-tested contracts that protect your assets and your users' trust.
- Custom Logic: DeFi protocols (
AMMs, lending/borrowing), NFT collections (ERC-721A,ERC-1155), DAOs, and enterprise utilities. - Security Rigor: Development with
OpenZeppelinstandards, comprehensive unit/integration testing, and pre-deployment review. - Full Lifecycle: Development, deployment scripting, verification on
Etherscan/Blockscout, and upgradeability planning.

PROVEN FRAMEWORK
Our Implementation Methodology
We deliver production-ready stablecoin payment networks in 8-12 weeks using our battle-tested, four-phase framework. This systematic approach ensures regulatory compliance, technical robustness, and seamless go-to-market execution.
01
Phase 1: Architecture & Compliance Blueprint
We define the technical and regulatory foundation, including multi-jurisdiction licensing strategy, tokenomics, and network architecture (e.g., EVM-compatible L2, CCTP integration). Deliverables include a comprehensive technical spec and compliance roadmap.

Frequently Asked Questions
Get clear answers on timelines, costs, and technical specifics for building your cross-border payment network.
A standard implementation takes 4-8 weeks from kickoff to mainnet launch. This includes 1-2 weeks for architecture design, 2-3 weeks for core smart contract development and internal audits, 1 week for integration with your existing systems (e.g., treasury, compliance), and 1-2 weeks for testing and deployment. Complex multi-chain or heavily customized compliance logic can extend this timeline.
