Circle Burns $250M USDC on Ethereum, Issues $910M on Solana as BNY Mellon Opens Institutional Mint Access

Circle USDC$1.000+0.3% burned $250 million USDC on Ethereum and issued $910 million on Solana on June 29, 2026, according to CryptoBriefing. The net effect: $660 million in USDC liquidity moved from Ethereum to Solana in a single day.

On the same day, BNY Mellon announced an expanded partnership with Circle that makes USDC the first stablecoin on BNY's Digital Asset Custody platform. The new capabilities let institutional clients store, transfer, mint, and burn USDC directly through BNY's existing custody infrastructure, with Solana and Ethereum as the initially supported chains for the mint and burn functionality.

The two events are unrelated operationally (one is a routine liquidity rebalancing, the other is a product launch), but arriving on the same date they describe the same structural shift: institutional stablecoin infrastructure is consolidating around Solana.

How the USDC Rebalancing Works

Circle manages its cross-chain USDC supply using the Cross-Chain Transfer Protocol (CCTP). The mechanics are straightforward: burn tokens on one chain, mint an equivalent amount on another. Total supply does not change. What changes is where the liquidity sits.

The June 29 operation ($250M burned on Ethereum, $910M minted on Solana) fits a pattern that has been running for months. We covered it first on June 8, when a $500M Solana mint pushed the network to 10.3% of total global USDC supply, its highest recorded share. On June 12, a $1 billion single-day mint pushed the 2026 gross cumulative issuance on Solana to approximately $57 billion. The June 29 rebalancing continues that trajectory, and notably adds a burn component: Circle is not just minting on Solana, it is actively pulling supply from Ethereum.

The $57 billion figure is gross cumulative issuance (the running total of all USDC minted on Solana throughout 2026), not Solana's current circulating USDC balance, which is a smaller figure representing what remains on-chain after redemptions. The distinction matters, but the cumulative number still describes the scale of demand Circle is seeing from Solana-based activity.

BNY Mellon Brings Institutional Mint and Burn to Solana

The BNY expansion is the more structurally significant development of the two. BNY Mellon oversaw $59.4 trillion in assets under custody and administration as of March 31, 2026, per its press release, making it the world's largest custodian. Until now, converting institutional dollars into USDC required going through Circle's own pipeline. The new setup lets BNY clients instruct Circle to mint or redeem USDC without leaving BNY's custody framework.

Kash Razzaghi, Circle's Chief Commercial Officer, called it "the next chapter in a longstanding relationship that now gives BNY clients connectivity between on-chain and traditional assets, within the infrastructure they already trust," according to BNY's press release.

BNY was already one of Circle's primary USDC reserve custodians, a role it has held since 2022. The new capability extends that relationship to include on-chain issuance and redemption. That Solana is one of the two chains explicitly supported at launch, alongside Ethereum, reflects where institutional USDC demand is concentrating.

Solana's USDC Share Keeps Expanding

USDC is now native on more than 30 networks, per Circle, including Ethereum, Solana, Base, Arbitrum, Avalanche, and Optimism. Ethereum remains the largest USDC chain by circulating balance. But the direction of travel over 2026 has been consistent: Circle is directing new issuance toward Solana at a pace that is gradually shifting the network's share of the overall supply.

The demand driving that issuance is real. Jeremy Allaire, Circle's CEO, noted at Breakpoint 2025 that USDC on Solana leads all chains in transaction volume, a metric that reflects actual usage in DeFi, payments, and institutional settlement rather than idle holdings. USDT remains the dominant stablecoin by market cap overall, but USDC's Solana presence has grown substantially through 2026 across both issuance and transaction activity.

The BNY channel adds a new source of that demand. Institutional clients who previously held dollars in BNY custody can now convert to USDC and deploy it on Solana or Ethereum without routing through a separate workflow. That frictionless on-ramp, built on the infrastructure of a $59.4 trillion custodian, is the kind of integration that creates durable rather than episodic USDC demand.

Solana Compass data shows the USDC holder base on Solana grew from 7.17 million wallets on June 6 to 7.60 million by June 29, a gain of roughly 430,000 wallets across that window. The live holder chart continues to update in real time.

Carolyn Weinberg, BNY's Chief Product and Innovation Officer, described the intent plainly in the press release: "With the addition of our enhanced stablecoin enablement capabilities, we're expanding the ways clients can move value with the operational scale, trust and resiliency they expect from BNY."

Whether the pace of Solana USDC issuance continues at this level depends on what institutional clients and DeFi protocols are actually doing with the liquidity once it lands. The supply side is clearly there. The question for the rest of 2026 is whether the usage metrics (transaction volume, DeFi TVL in USDC pools, settlement activity) keep pace with the minting.
