BTC Fee Forecaster

Forecasting Bitcoin transaction fee rates based on mempool data

BTC Fee Forecaster provides optimal transaction fee rate suggestions over a 24-hour forecast horizon (at minute intervals; updated every 5 minutes) based on simulated forecasts of future fee rates using current and historical Bitcoin mempool data. To date, BTC Fee Forecaster is the only solution that provides a comprehensive framework for understanding how Bitcoin fee rates will change in the near future. Our API provides an easy way to access the forecasts, giving you an essential source of alpha.

How To Use: BTC Fee Forecaster is best used with existing fee estimators such as mempool.space, BitcoinFees, BlockCypher, or any Bitcoin wallet that provides fee estimation functionality. Our API endpoint provides 3 different confidence levels of a transaction being verified at that timestamp with the provided fee rate, assuming a block is mined. This differs greatly from existing fee estimators, typically giving you suggested fee rates to verify your transactions in the next 1-6 blocks. BTC Fee Forecaster can identify a particular time or fee range of interest within the 24-hour window; within this range, existing fee estimators can be used to provide a fee suggestion. Note: BTC Fee Forecaster has no customized logic on top of the forecast that fits your particular product or use case. Just as the weather app does not tell you to go outside or not, our forecaster does not tell you when to submit transactions. Please connect with the team for further details.

Disclaimer: BTC Fee Forecaster is currently in R&D Production v1.0. Technical fixes, documentation revisions, and feature improvements are continuously being made to the product. Please contact Matt (Head of Blockchain Research; [e-mail]) to connect with the team.
