USDC and USDT are issued natively on many chains; this reads their supply directly from the token contract on Ethereum, Base, Arbitrum, Optimism, Polygon and Avalanche. The stablecoin endpoint gives one stablecoin's supply per chain (USDC or USDT) with the Ethereum-versus-rollup split; chains ranks the chains by their total native stablecoin liquidity; summary is the top-down view — total USDC, total USDT, the ratio and Ethereum's dominance versus the rollup share. Dollar-pegged and read at each token's on-chain decimals, so supply equals dollars. The stablecoin chain-distribution cut — distinct from the single-chain token feeds, the generic stablecoin-supply aggregators and the price feeds.",
