PROVEN METHODOLOGY
Our Development & Verification Process
A rigorous, multi-layered approach designed to deliver secure, production-ready Move messaging protocols with predictable timelines and zero critical vulnerabilities.
01
Architecture & Specification
We define the protocol's formal specification, including message flow, state transitions, and security invariants. This creates a single source of truth for developers and auditors.

Frequently Asked Questions
Get clear answers on our process, security, and deliverables for building secure messaging protocols on Move-based blockchains.
Our process is structured for clarity and security. It begins with a technical discovery workshop to define your specific use case (e.g., cross-chain attestations, private group chats). We then deliver a detailed spec and architecture document. Development follows a sprint-based model with weekly demos. Every project concludes with a formal security audit and comprehensive documentation before mainnet deployment.
