PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to implementing private metadata solutions, designed for predictable delivery and seamless integration into your existing media or NFT platform.
01
Discovery & Architecture Design
We analyze your specific use case—be it gaming assets, digital art, or confidential documents—to design a tailored architecture. This includes selecting the optimal encryption standard (e.g., AES-256-GCM), access control model, and on/off-chain data flow.
1-2 weeks

Zero Trust
Architecture Principle
02
Smart Contract & Key Management
Development of secure, auditable smart contracts for access control and token-gating, paired with a robust key management system. We implement industry standards like ERC-4906 for metadata updates and secure enclaves or MPC for private key operations.
