The **bitfinex-terminal-key-encoding** package provides custom key‑encoding logic for Hyperbee databases that store Bitfinex terminal data (trades and candle records). By supplying this module as the `keyEncoding` option, developers can perform range queries on fields such as `timestamp` and `candle` (e.g., 1m, 5m) directly against a Hyperbee feed, making it useful for anyone building market‑data services or analytics tools on top of Bitfinex’s decentralized market data streams.
