unprobed
EURC peg monitor — unique combined signal: the official ECB euro reference rate (USD/EUR) versus the live on-chain EURC/USDC price from the deepest Uniswap v3 pool on Base, returned as a deviation in basis points with both source values and timestamps. Tells agents holding or pricing EURC how far the on-chain euro stablecoin trades from the official euro. No input required.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
