Circle mints 500 million USDC on Solana

Circle minting 500,000,000 USDC on Solana signals increased stablecoin liquidity and settlement capacity on the network, which can support near-term on-chain trading activity, DeFi collateral availability, and exchange flows. The mint itself is not demand, but it typically reflects anticipated issuance needs from market makers or venues, making Solana's ecosystem the most directly impacted.
