PREDICTABLE, TRANSPARENT, AND FAST
Our Delivery Process: From Spec to SDK
We provide a structured, milestone-driven delivery process that ensures your AppChain messaging SDK is built to spec, on time, and ready for production. This is how we guarantee a seamless integration and rapid time-to-market for your project.
01
1. Discovery & Architecture
We start with a deep technical dive into your AppChain's consensus, data structures, and use cases. We deliver a detailed technical specification and architecture document, ensuring the SDK is perfectly tailored to your chain's unique requirements.

AppChain Messaging SDKs: Common Questions
Get specific answers about our development process, security, and support for your custom messaging layer.
We deliver a production-ready, audited AppChain messaging SDK in 4-8 weeks for most projects. The timeline breaks down as: Week 1-2 for architecture and specification, Week 3-5 for core development and internal testing, and Week 6-8 for security audits and final integration support. Complex features like cross-chain validation or advanced privacy (ZK) can extend this by 2-3 weeks.
