What this gives you
Live on-chain data
Claude connects directly to ChainFundamentals datasets — answers are grounded in real, up-to-date blockchain data, not the model's training knowledge.
Ask in plain language
No SQL or coding needed. Just ask Claude questions about Sky, Ethena, Morpho, Maple Finance, and the yield coin landscape — it queries the data automatically.
Transparent & verifiable
All datasets are built from open-source Dune queries. The underlying on-chain data can be independently verified by anyone.

"What has happened to total USDS demand over the past six months? Has growth come from retail or whale wallets?"
"Show me Sky's gross cash inflows and outflows over the last quarter. Is the capital buffer growing or shrinking?"
"How has the distribution of SKY token holders changed over the past year? Are whale wallets increasing or decreasing as a share?"
"How many wallets are currently depositing into Lockstake, and has participation been growing in recent months?"
"How has the number of syrupUSDC holders trended over the past year? Is the holder base growing?"
"Compare total USD deposits across sUSDS, sUSDe, and syrupUSDC over the past year. Which has seen the strongest growth?"
