Stablecoin Index

The Stablecoin Index service tracks peg stability, market dominance, and chain distribution for 14 major stablecoins. Each stablecoin receives a stability score (0–100) with letter grades.

Peg prices are sourced from CoinGecko; chain distribution and dominance history from DefiLlama. Stability scores and letter grades are Bitcompare's own calculation applied to this data.

Name
Average Deviation (30%)
Description
Mean deviation across all data points.
Name
Time-Weighted Deviation (20%)
Description

Name
Recovery Speed (20%)
Description
How quickly the price returns to peg after a depeg event.
