EVM Oracle SDK Development: Frequently Asked Questions
Get clear answers on timelines, costs, security, and process for building a custom oracle SDK with Chainscore Labs.
A production-ready, audited EVM Oracle SDK typically takes 4-8 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture design and smart contract development, 2-3 weeks for SDK library and off-chain components, and 2 weeks for comprehensive security audits and testing. For simpler integrations or price feeds, timelines can be as short as 2-3 weeks.
