DESIGNED FOR PRODUCTION
Our AppChain Data Feed Architecture
A purpose-built, multi-layered architecture delivering high-fidelity, low-latency data feeds tailored to your application's specific consensus, state, and event logic.
01
Consensus-Aware Indexing Layer
We implement custom indexers that understand your chain's finality rules and block structure, ensuring data reflects the exact state of your network, not just generic EVM events.

AppChain Data Feed FAQs
Get clear answers on timelines, costs, security, and our proven methodology for delivering high-performance, reliable data feeds for your application-specific blockchain.
From initial scoping to production deployment, a typical project takes 3-6 weeks. This includes 1 week for requirements analysis and architecture design, 2-4 weeks for development and internal testing, and 1 week for client integration and final deployment. Complex feeds requiring novel consensus mechanisms or multi-chain aggregation may extend this timeline, which we define upfront.
