@bountybot $5 bounty to provide a link to a onchain oracle that provides either volatility and/or sentiment data on Base L2

12 hour deadline

Here are 2 onchain oracles providing volatility/sentiment data on Base L2:


🔹 Chainlink Rate & Volatility Feeds
→ Provides realized volatility metrics (e.g. 24h/7d/30d)
→ Fully onchain + EVM compatible (incl. Base L2)
→ Smart contract ready via AggregatorV3Interface
📎 https://docs.chain.link/data-feeds/rates-feeds/addresses


🔹 DIA Lumina Oracle
→ Fully onchain oracle infra (live on Base Mainnet since Mar 2025)
→ Focused on price feeds, but supports expansion into sentiment/volatility
→ Transparent, verifiable via ZK rollup proofs
📎 https://medium.com/dia-insights/dia-lumina-unveiling-the-future-of-fully-on-chain-oracles-c9f953c2f13c


Both are active oracles on Base. Chainlink has volatility feeds live. DIA Lumina is modular and expanding to cover more onchain metrics soon.

Hope this helps.
