Circle minted $3 billion in USDC on Solana over a 24-hour period, one of the network’s largest single-day issuances to date. The mint extends a broader 2026 expansion in Solana-based USDC liquidity, including approximately $11 billion in gross issuance during August and circulating supply above $8 billion by late that month, more than 10% of global USDC supply for the first time. Circle’s issuance has included repeated $250 million tranches, a $1 billion single-day mint in June and $1.25 billion issued over three days in early September. Gross minting does not equal net supply growth because redemptions and burns continue. BNY Mellon expanded its collaboration with Circle in June 2026 to support institutional USDC minting and custody directly on Solana, where lower fees and faster finality can facilitate large stablecoin settlements. A June 29 transaction paired a $910 million Solana issuance with a $250 million Ethereum burn, highlighting a shift in stablecoin activity while Ethereum remains the largest USDC venue.
