USDC Treasury Mints 500M USDC on Solana in Two Batches

Two back-to-back mints of this size on Solana point to issuer-side liquidity provisioning rather than organic demand alone, since treasury mints often precede deployment into circulation rather than reflect it directly. Solana's role as the venue is the more telling detail, reinforcing its standing as a preferred rail for stablecoin settlement activity. Whether the freshly minted supply actually moves into active onchain use or sits idle is the open question worth watching.
