Frequently Asked Questions
Get clear answers on integrating secure, reliable off-chain data into your Cosmos application.
A standard integration with a major data provider (e.g., Chainlink, Pyth) takes 2-4 weeks from kickoff to mainnet deployment. This includes smart contract development, testing on testnet, and security review. Complex multi-feed or custom aggregation logic can extend this to 6-8 weeks.
