USDC Treasury mints 250M USDC on Solana

A single $250 million mint is routine treasury mechanics rather than a market signal on its own, but the venue matters: Solana has become a preferred rail for stablecoin liquidity, and supply growth there reflects where demand for dollar settlement is concentrating. The read-through is less about the headline number than about whether this freshly minted supply gets absorbed into on-chain activity or sits idle. Watching subsequent burns or redemptions, and whether Solana's share of USDC supply keeps climbing, is the more telling indicator.
