According to the source, data from Artemis shows Ethereum added $84.9B in stablecoin supply over the past 12 months, leading all networks by net inflows (source: Artemis). Stablecoins function as the primary quote currency and collateral across centralized and on-chain markets, so rising supply directly increases deployable liquidity for BTC, ETH, and ERC-20 trading and lending (sources: Binance Research, Glassnode). For execution, traders can track USDT and USDC net mint/burn on Ethereum and confirm follow-through via DEX volumes and depth to assess risk-on rotation (sources: Artemis, DefiLlama).
