Frequently Asked Questions
Get clear answers on our process, timeline, and technical approach for building your custom cross-chain oracle.
We deliver a production-ready, audited Substrate pallet in 4-6 weeks for a standard oracle implementation. This timeline includes requirements analysis, architecture design, development, internal testing, and a final security audit. Complex integrations with multiple external data sources or novel consensus mechanisms may extend this to 8-10 weeks. We provide a detailed project plan with weekly milestones upon engagement.
