Circle Minted $11 Billion in USDC on Solana in August, Pushing Solana Past 10% of Total Supply

Circle USDC$1.0000.0% minted roughly $11 billion in USDC on Solana during August 2026, the largest single-month issuance the network has received, according to on-chain monitoring data reported by CryptoBriefing on September 1. By late August, Solana's circulating USDC supply had reached approximately $8 billion, crossing above 10% of total USDC supply across all networks for the first time.

Compass holder-trends data shows $8.10 billion in USDC circulating on Solana on August 31, consistent with CryptoBriefing's reporting and providing a first-party data point for the 10% threshold.

As we covered in late June, when Circle burned $250M USDC on Ethereum and minted $910M on Solana in a single day, the pace of Solana-side USDC issuance had been rising through 2026. August's $11 billion total shows that June event was not a one-off. The pace has continued and accelerated.

How $11 Billion in Minting Produces $8 Billion in Supply

The gap between $11 billion minted and $8 billion circulating reflects standard USDC mechanics. Each issuance is backed one-for-one by USD reserves held by Circle: a counterparty deposits dollars, receives USDC on Solana, and can redeem at any time. Gross monthly minting accumulates across all issuance events; circulating supply captures the net of those issuances minus redemptions and burns.

August's gross issuance ran in repeated $250 million tranches throughout the month, including a $1 billion single-day print and a $1.25 billion one-week burst in mid-to-late August, per CryptoBriefing's Whale Alert sourcing. By the week ending August 26, the weekly USDC issuance rate across all blockchains had reached $5 billion — a pace that reflects the scale of demand Circle was provisioning against.

The Demand Chain: Hyperliquid's Reserve and BNY Mellon's Pathway

The $250 million tranches are institutional-sized transfers, each one representing a single counterparty depositing equivalent dollars with Circle and receiving USDC on Solana. Two demand sources help explain what was driving them.

Hyperliquid holds a $5 billion USDC reserve, per CryptoBriefing, and Circle is the technical deployer for that reserve. When capital inflows to Hyperliquid's perpetuals platform grow, the reserve grows, and Circle provisions the corresponding USDC through its Solana mint pipeline. Hyperliquid's scale as one of the largest on-chain perpetuals platforms makes it a consistent source of demand for Solana-native USDC issuance.

BNY Mellon's institutional pathway, opened in late June, also contributed. BNY Mellon made USDC the first stablecoin on its Digital Asset Custody platform, with Solana supported for institutional mint and burn. That gave traditional financial institutions a regulated custodian route to Solana-native USDC without requiring them to manage blockchain infrastructure directly. Both are structural commitments: a regulated custodian's infrastructure does not switch off in a bear market, and a perpetuals platform's reserve requirement does not contract when spot prices fall.

From April's Record to August's Run Rate

The acceleration from April to August is the clearest signal in the data. Circle minted $3.25 billion on Solana in April 2026, a record at the time. August ran at roughly 3.4 times that pace.

What distinguishes August is not one extraordinary transaction but consistent institutional-scale issuance across the month. Repeated $250 million tranches, sustained through August, point to steady counterparty demand rather than a single large event inflating the total. At $11 billion, the monthly total is the aggregate of that sustained activity.

The 10% supply threshold is the concrete outcome. Solana ended August holding more than one dollar in ten of USDC in global circulation. No chain other than Ethereum had previously reached that share.

Solana as Settlement Infrastructure for USDC at Scale

Institutions moving $250 million or more in a single USDC transfer need settlement infrastructure that is fast, inexpensive, and predictable. Solana USDC transfers settle in under a second at sub-cent fees. Block times moved to approximately 350 milliseconds following the August 21 slot-time reduction, per Anza. Those characteristics matter for transfers at this scale in ways they do not for retail-level activity.

The growing number of wallets holding USDC on Solana runs alongside the institutional figures. Compass data shows Solana's USDC holder base grew from 7.17 million wallets in early June to 8.70 million by August 31 — a 21% increase in three months that spans both retail and institutional wallet growth.

The result is that Solana's USDC infrastructure is operating as a primary settlement layer for institutional issuance, not just a venue for DeFi activity denominated in USDC. Settlement infrastructure demand tracks the institutions that have committed to it, which tends to be more stable than demand tied to market conditions or trading volume.

What the $11 Billion Total Measures and What It Doesn't

One important qualification: the $11 billion August total comes from Whale Alert, which monitors large on-chain transactions. Circle has not independently confirmed this monthly figure. Circle's transparency dashboard publishes chain-level supply data but does not break out monthly gross minting totals. CryptoBriefing applies appropriate hedging ("roughly," "around") because Whale Alert observes activity rather than receiving direct issuer disclosure. Compass's own supply data shows $8.10 billion circulating on August 31; the $11 billion gross minting figure depends on aggregated transaction monitoring.

Ethereum also retains a commanding lead in total USDC circulation. Solana crossing 10% does not displace Ethereum. It moves Solana from peripheral to significant within the USDC supply picture. The pace of that movement, driven by identifiable institutional demand rather than speculative flows, is what makes the August figures meaningful.
