Blended Bitcoin Fee Estimations

The Context

Bitcoin fee estimation sounds simple: look at the mempool, pick a fee rate, broadcast. In practice, it's a prediction problem wrapped in a game theory problem.

Get it wrong and your transaction sits in mempool purgatory. Get it very wrong and you overpay by 10x.

Why This Matters

At Strike's scale, fee efficiency directly impacts the bottom line. We couldn't rely on a single estimation source. We needed a system that weighted multiple signals intelligently.

This post details our blended approach - the data sources, the weighting algorithm, and the real-world accuracy improvements we measured.
