Circle Mints 500M USDC on Solana

The signal here is where the liquidity is landing, not the size of the mint: Circle expanding USDC supply on Solana points to stablecoin demand concentrating on a chain chosen for throughput and low fees rather than Ethereum. That matters for Solana-based DeFi and payments venues that price and settle in dollars, and for the broader question of whether issuance keeps migrating toward faster networks. Whether this reflects durable demand or a routine treasury operation ahead of expected activity is the open question.
