Stablecoin supply by asset

Stablecoins ranked by circulating supply from DefiLlama's free stablecoin dataset: name, symbol, peg currency and type (USD, EUR, JPY, VAR...), peg mechanism (fiat-backed, crypto-backed, algorithmic), current price and USD peg deviation, circulating supply in peg units and USD, 1d/7d/30d supply change, and per-chain circulation (top chains + count). Filter by peg currency, mechanism, chain (then ranked by supply on that chain) or a name/symbol search; limit up to 100. Totals carry matched circulating USD. Keyless public data.
