TRANSPARENT & PREDICTABLE
Our Delivery Process: From Architecture to Audit
We deliver production-ready Bitcoin L2 Data Availability layers with a structured, milestone-driven approach. This ensures predictable timelines, clear communication, and a final product that meets enterprise-grade security and performance standards.
01
1. Architecture & Design
We define the technical architecture, consensus mechanism, and data sharding strategy for your Bitcoin L2. This includes selecting the optimal DA bridge (e.g., BitVM, RGB++) and designing for scalability and cost-efficiency.

Bitcoin L2 Data Availability: Key Questions
Essential questions for CTOs and technical founders evaluating a Bitcoin L2 data availability layer for their protocol.
A standard integration takes 2-4 weeks from kickoff to mainnet deployment. This includes environment setup, custom adapter development, security review, and final testing. For novel consensus mechanisms or complex state transition logic, the timeline may extend to 6-8 weeks. We provide a detailed project plan within the first 3 days of engagement.
