203 Stock Tokens trade on Robinhood Chain. Chainlink prices 33 of them. The other 170 are blind — no contract can read their price. TailFeed prints the missing price tags, and watches every feed on the chain for errors — including Chainlink's 33.

Feeds speak the exact AggregatorV3 language. If your contract already reads Chainlink, swap the address — nothing else.
// Solidity — unchanged Chainlink integration
AggregatorV3Interface feed = AggregatorV3Interface(
0xD320f571eC76eD9430B31e22bB2650bB4cfaae9C // TAIL CIEN/USD
);
(, int256 answer,, uint256 updatedAt,) = feed.latestRoundData();
// answer = 26401500000 (8 decimals)
// check : block.timestamp - updatedAt < 300// JavaScript — plain JSON-RPC, no library needed

- Source verified on the chain's own explorer — every contract, click and read it.
- No hidden powers: no mint, no upgrade, no owner functions. One fixed pusher, set at construction.
- Reads are free — adoption is the business, not gas-farming.
- Watched: every feed (ours and Chainlink's) is checked against the exchange's own quotes. We already caught one sitting 0.40% off.
- Testnet now, mainnet after it survives days of rounds. No token — none is needed to use any of this.
