PROVEN METHODOLOGY
Our Delivery Process: From Architecture to Deployment
A structured, transparent workflow designed for technical leaders. We deliver production-ready AppChain synchronization modules with clear milestones, predictable timelines, and zero architectural debt.
01
Phase 1: Architecture & Protocol Analysis
We conduct a deep technical audit of your AppChain's consensus, data structures, and RPC endpoints. This defines the synchronization scope, identifies edge cases, and establishes the final data schema for your off-chain services.
Deliverable: Technical Specification Document & Integration Roadmap.

Frequently Asked Questions
Get clear answers on our development process, timelines, and support for your custom synchronization modules.
From initial design to mainnet deployment, a standard AppChain-specific synchronization module takes 4-6 weeks. This includes 1 week for architecture design, 2-3 weeks for core development and internal testing, and 1-2 weeks for client review, final testing, and deployment. Complex multi-chain or high-frequency data syncs may extend this timeline, which we scope and quote for upfront.
