Ever wonder which blockchain actually offers the most stable fee environment? There's a practical way to measure this.

Enter the Fee Stability Ratio (FSR)—a metric that lets you compare chains by looking at two key factors: what their median transaction fee actually is, and how wild that fee swings around.

The math is straightforward:

FSR = 1 / (Median Fee × Median Fee Volatility)

Simple rule: higher FSR wins. A chain with low fees that stay predictable? That's FSR territory. One where you get surprise gas spikes? Expect a rougher ratio.

This matters because traders and developers hate uncertainty. A stable fee structure means better planning, predictable costs, and fewer blown budgets. When you rank chains this way, the efficiency leaders show themselves pretty quick.
