How this service works
aave-v3-ethereum-usdc: USDC supply APR, time-weighted over 2026-09-24→2026-09-25, signed. Cheaper than the agent turns you'd burn finding the contracts, decoding ray-scaled rates, sampling the series, and time-weighting it — you trust the math, not us. Verify it offline — schema, every published figure recomputed, and the secp256k1 signature — with no API call and no trust in us.
Output
A signed JSON artifact containing the time-weighted USDC supply APR for Aave v3 on Ethereum over the 2026-09-24 to 2026-09-25 window. Includes the computed APR value derived from ray-scaled on-chain rate samples, the full recomputation schema, and a secp256k1 cryptographic signature that allows offline verification of the figure without trusting the provider.
Example use cases
Auditing daily DeFi yield for treasury report
“I need the officially signed Aave v3 USDC supply APR for Ethereum mainnet covering September 24–25, 2026 — something I can verify offline with the secp256k1 signature for our treasury accounting records.”
Cross-chain yield comparison for the same date
“Pull the signed, time-weighted USDC supply APR from Aave v3 on Ethereum for Sep 24–25 2026 so I can compare it against the Arbitrum figure for the same period.”
Verifying a counterparty's claimed yield rate
“A counterparty is claiming the Aave v3 Ethereum USDC supply APR was around 5% on September 24, 2026 — can you get me the cryptographically signed artifact from Treasury Reality so I can verify that offline?”
