PROVEN FRAMEWORK
Our Delivery Methodology
We deliver secure, production-ready fraud detection systems through a structured, transparent process designed for fintech and Web3 enterprises. Our methodology ensures predictable outcomes, clear milestones, and seamless integration.
01
Threat Modeling & Architecture
We begin with a comprehensive risk assessment to define your threat landscape. Our architects design a modular ledger system with real-time anomaly detection, multi-signature controls, and immutable audit trails.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your protocol.
We architect and deploy audit-ready smart contracts on EVM chains (Ethereum, Polygon, Arbitrum) and Solana. Our development process is built on OpenZeppelin standards and rigorous security patterns, ensuring your core logic is robust from day one.
- Custom Logic: Tailored
ERC-20,ERC-721,ERC-1155, and bespoke DeFi/GameFi contracts. - Security-First: Multi-stage review using static analysis, formal verification, and internal audits.
- Gas Optimization: Every contract is optimized for minimum execution cost and maximum efficiency.
We deliver a complete development package: source code, comprehensive documentation, and deployment scripts, enabling your team to launch with confidence in as little as 4-6 weeks.

Frequently Asked Questions
Get clear answers on how we build secure, real-time ledger systems for FinTechs and Web3 companies.
We deploy a modular, API-first ledger system that connects to your core banking, payment rails, or DeFi protocol via secure REST or WebSocket APIs. Our standard integration uses a sidechain or dedicated L2 (like Polygon, Arbitrum) for real-time transaction analysis, ensuring no disruption to your main production chain. Typical integration is completed in 2-3 weeks, including a full security audit of the integration points.
