Circle Mints 750M USDC on Solana in 24 Hours

Circle’s USDC infrastructure minted another 250 million tokens on Solana on September 30, bringing reported gross minting over the preceding 24 hours to 750 million USDC. On-chain monitoring from Onchain Lens tracked the latest transaction as part of the three-quarter-billion-dollar burst. The activity confirms substantial USDC treasury operations on Solana, but it does not establish that $750 million of new USDC entered circulation or flowed into crypto markets.

That distinction is particularly important on Solana. According to Circle’s official documentation on USDC pre-minting, the issuer can create tokens and hold them at designated pre-mint addresses before they are considered circulating. USDC held in those addresses remains excluded from circulating supply until Circle authorizes its distribution to users. A customer receiving USDC from a pre-mint balance increases circulation; sending USDC back into that infrastructure reduces it.

Gross Minting Does Not Equal New Capital

The latest activity follows repeated large Solana issuance events throughout September. Earlier in the month, Circle recorded a roughly $3 billion burst of USDC treasury mints within 24 hours, while individual 250 million-token batches have appeared repeatedly. Those transactions demonstrate that Circle is maintaining substantial issuance capacity on Solana, but gross minting must be separated from net supply growth because redemptions and treasury movements can occur alongside issuance.

Circle’s own global data illustrates the difference. The company reported approximately $75.2 billion of USDC in circulation as of September 24, while mint and redemption activity routinely runs much higher over time as customers move between dollars and USDC. A token can be minted, distributed, redeemed and effectively removed from circulation without representing permanently incremental capital. Circle describes minting as part of its institutional issuance and redemption system rather than a direct indicator of investment demand.

The distinction also means the latest 750 million should not automatically be described as new DeFi liquidity. Earlier Digital Coin Journal coverage of another 250 million USDC Solana mint similarly showed why treasury creation alone cannot reveal whether tokens have reached exchanges, lending protocols, liquidity pools or payment applications. Distribution out of Circle-controlled inventory is the more relevant step for determining whether newly created tokens have become active circulating balances.

Solana Remains a Major USDC Distribution Rail

Solana nevertheless has a substantial operational role within Circle’s multichain system. Circle supports native USDC issuance and redemption on the network, rather than relying on a wrapped representation bridged from another blockchain. Its Solana product documentation positions the asset for trading, financial services and payments while retaining 1:1 redemption against U.S. dollars for eligible Circle Mint customers. Native issuance makes Solana a direct USDC distribution rail, even when individual treasury mints cannot reveal the eventual use of those tokens.

There are separate examples of USDC moving into identifiable Solana use cases. Jupiter’s Universal Deposit routes assets from other chains into native Solana USDC, while Visa has used the network for USDC settlement between participating U.S. financial institutions. Those live workflows provide stronger evidence of stablecoin utility than a mint transaction alone because they identify how USDC is actually being transferred or settled.

The transaction link originally associated with the September 30 event does not support that date: Whale Alert identifies it as a separate 250 million USDC mint completed on June 11, 2026, with the tokens received by an address it labels USDC Treasury. The September 30 monitoring nevertheless supports the broader 750 million gross-mint figure over the preceding 24 hours. The defensible conclusion is therefore that Circle created another large block of USDC inventory on Solana, while the resulting change in circulating supply must be measured separately from the headline mint total.
