Live USDC yield panel on Base, read DIRECTLY from chain state — Aave v3, Compoun
Live USDC yield panel on Base, read DIRECTLY from chain state — Aave v3, Compound v3, Moonwell, Euler v2 supply APY from onchain rate views, plus the six largest Morpho (MetaMorpho) USDC vaults with REALIZED trailing APY from ERC-4626 share-price deltas (archive reads, net of fees — not a vendor estimate). Optional: any custom ERC-4626 vault address on Base. Built for yield agents (Sail/Sailor, rebalancers, treasury bots) that need verify-before-acting numbers.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
