COINBASE CUTS USDC ON-RAMP FEES ON BASE AS CIRCLE BUILDS STABLECOIN L1

Summary from the TLDR Crypto newsletter

Coinbase and Mercuryo have partnered to slash USDC on-ramping fees by ~50% for MetaMask users on Base, as Circle plans a USDC-native Layer 1. The move comes amid growing institutional interest in stablecoins post-GENIUS Act and Circle's report of 90% YoY USDC supply growth to $61.3B. With Base gaining traction and Circle leaning into vertical integration, USDC is positioning as the central rail for stablecoin-native infrastructure.
