How this service works
How close USDC lending on Base is to the kink where borrow rates explode: per-protocol utilization, the kink read from the protocol's own rate curve, headroom in bps, and borrow APY at points around it. Aave and Compound only — Morpho's adaptive IRM has no static curve and DefiLlama-sourced protocols expose none, so they are marked unmeasured, never assumed stable. Describes state, not a forecast. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.
Output
A structured response containing per-protocol utilization rates, the kink threshold read from each protocol's on-chain rate curve, headroom expressed in basis points, and borrow APY sampled at points around the kink. Aave and Compound are fully measured; Morpho is marked unmeasured due to its adaptive IRM lacking a static curve. Describes current on-chain state only, not a forecast.
Example use cases
Pre-deposit rate spike risk check
“Before I move $500k USDC into lending on Base, can you check how close Aave and Compound are to the kink on their rate curves — I want to know the headroom in basis points so I don't get caught in a borrow rate explosion.”
Monitoring kink proximity for active position
“I have USDC sitting in Aave on Base — can you pull the current utilization and kink headroom so I can see if rates are about to spike?”
Comparing protocol rate curve exposure
“Give me a side-by-side of how close Aave versus Compound are to their USDC rate kinks on Base right now, including borrow APY at points around the kink.”
Technical details
Endpoint
GEThttps://yieldsignal.vercel.app/sensitivity/usdc-base-yield?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to assess kink proximity and rate curve headroom for USDC lending on Base across Aave and Compound. Prefer it over general yield endpoints when your concern is borrow rate spike risk rather than raw APY ranking. Not suitable when you need Morpho data or forecasts; use sibling endpoints for WETH sensitivity or exit capacity analysis.
Side effects
- Protocol data unavailable if on-chain RPC is unreachable
- Morpho always returned as unmeasured — not a failure but an expected limitation
- Payment not processed returns 402
- Rate data may lag a block or two behind real-time on-chain state
