What it returns

Every price oracle ranked by the DeFi value it secures today (the value locked in the protocols relying on it, in USD), each with the protocols it secures, most value first: the top ten, or every one when oracle names it. Across every chain, or on the one in chain. A protocol relying on two oracles appears under both, each with its own part of the value; Internal and TWAP are protocols pricing themselves. Borrowed, staked, pool2 and vesting value are not counted. chains and chainCount describe where the oracle secures anything, whatever chain is. On a chain no oracle secures anything on (STABLE today), oracles is empty.
