About the FETH/USD Pyth feed
The FETH/USD feed (FIDELITY ETHEREUM FUND / US DOLLAR) is an aggregated equity price published on-chain by the Pyth Network — a first-party oracle sourcing quotes from institutional publishers including exchanges, market makers and trading firms. Each update carries a confidence interval (±), an exponent and a publish timestamp, currently around $0.000. PythFeeds streams this feed live from the Hermes API and surfaces its staleness so you can see exactly how fresh the oracle price is.
