Stablecoin Supply

by stableintel-supply in Onchain & crypto

x402 APIPassing, checked 45 min ago

Supply facet for a stablecoin: total circulating supply plus the per-chain breakdown from DefiLlama, cross-checked against an INDEPENDENT on-chain ERC-20 totalSupply read of the curated contract, with a divergence flag when the two disagree beyond a tolerance. Cited to both the open-data source and public on-chain state.
