Circle’s USDC Treasury minted $250 million on Solana on August 20 as part of $1.25 billion in weekly issuance, the highest pace since April when $3.25 billion was printed across thirteen tranches. Cumulative gross issuance reached $68.26 billion by mid-July, with circulating supply at $8.27 billion as of August 22 held by 8.39 million wallets. Minting is reactive and occurs only after fiat deposits from market makers, exchanges, or institutions. Key demand comes from DeFi protocols including Jupiter, Kamino Finance, and Raydium, alongside institutional settlement. A June 29 single-day mint of $910 million followed BNY Mellon enabling institutional access. Solana DEX volume hit $7.31 billion on August 21. The gap between gross and circulating supply reflects active token turnover rather than accumulation, with USDC maintaining its peg.
