Quarterly data on stablecoin adoption: supply, volume, holder distribution, and use cases across the major networks.
The data behind stablecoin adoption.
The Stablecoin Index is Circle Research's quarterly read on how stablecoins are actually being used — measuring supply, transaction volume, holder distribution, and the mix of payments, trading, DeFi, and treasury activity across major networks.
It's the dataset institutions and policymakers use to separate signal from noise as the onchain economy matures.
