Circle minted about 500 million USDC on the Solana blockchain (high-speed public network) in the past 24 hours, according to monitoring by SolanaFloor.

In crypto markets, fresh stablecoin issuance is commonly watched as a sign of rising liquidity available for transfers, trading, and settlement across blockchain-based applications.
