Hedera Node Health Oracle FAQ
Get answers to the most common technical and commercial questions about deploying and managing a custom Hedera Consensus Node Health Oracle.
A standard, production-ready Hedera Node Health Oracle deployment typically takes 2-4 weeks from kickoff to mainnet launch. This includes architecture design, smart contract development, off-chain service integration, comprehensive testing, and deployment. Complex requirements like multi-signature governance or custom alerting systems may extend this timeline, which we scope and quote for upfront.
