According to a June 4 report by crypto platform CEX.io, automated bots facilitated over 4.84 million stablecoin transfers, driving $480 billion in trading volume on Ethereum Layer-1 in May 2025 — its highest ever.Bots Boost Efficiency, Push USDC to the TopOnce criticized for controversial strategies like MEV and sandwich attacks, trading bots are now being credited with improving liquidity and stabilizing Ethereum's DeFi ecosystem. In May, bots elevated stablecoin swaps to 32% of all Ethereum DEX volume, up from 37% in April. USDC became the most-traded asset on the network.CEX.io’s lead analyst Illia Otychenko attributes the comeback to lower gas fees in Q1 2025, which reversed user and liquidity migration trends to Ethereum layer-2 solutions and alternative chains.Ethereum's Mainnet Sees 11% Stablecoin Market Cap GrowthThe renewed demand for stablecoin utility drove an 11% increase in mainnet stablecoin market capitalization in 2025.

Cross-layer cost and liquidity fragmentation remain a barrier, threatening Ethereum’s ability to maintain its leadership in DeFi infrastructure.“This isn’t just a technical issue. It’s what will decide whether Ethereum leads or lags in the next phase of adoption,” Otychenko told Cointelegraph.
