Circle transferred approximately $4 billion in USDC to Coinbase-linked addresses on HyperEVM on June 12, 2026, marking the largest recorded USDC transaction to date. The transfer followed Circle's appointment as the official USDC deployer on Hyperliquid about a week earlier, representing a planned deployment rather than a sudden liquidity move. The transaction routed the equivalent of 5.3% of USDC's $76 billion circulating supply through HyperEVM, the smart contract environment built on Hyperliquid's Layer-1 blockchain, signaling that stablecoin infrastructure is expanding beyond Ethereum into newer blockchain networks.
Circle Transfers $4 Billion USDC to Coinbase on HyperEVM
Circle routed roughly $4 billion in USDC to Coinbase-linked addresses on HyperEVM on June 12, 2026. The timing aligned with Circle's formal designation as the official USDC deployer on Hyperliquid, which was announced about a week before the transfer. This transaction served as the first major live test of that operational setup.
Transaction Represents 5.3% of USDC Circulating Supply
The $4 billion transfer represents 5.3% of USDC's $76 billion circulating supply. The transaction was executed in seconds on-chain. No previous USDC transfer has reached this figure on record, making this transaction the largest recorded USDC transfer to date.
Hyperliquid AQAv2 Manages USDC Bridging at 9:1 Ratio
The transfer operates through Hyperliquid's AQAv2 system, which manages USDC bridging and rebalancing across the protocol at a 9:1 ratio. This ratio determines how liquidity is distributed across the network's architecture. The $4 billion transfer served as the system's largest real-world stress test.
Circle Appointed Official USDC Deployer on Hyperliquid
Circle was designated as the official USDC deployer on Hyperliquid approximately one week before the June 12 transfer. Under this arrangement, Circle controls the technical deployment of USDC on the network, applying the same operational model it uses on Ethereum and other supported chains. This formal role provided the framework that enabled a transfer of this magnitude.
Circle and Coinbase Co-Founded USDC Through CENTRE Consortium
Circle and Coinbase co-founded USDC through the CENTRE Consortium. Their commercial relationship includes revenue sharing on yield generated by USDC's reserves. Circle handles technical deployment and issuance, while Coinbase manages treasury operations. This operational structure has governed USDC since its launch and now extends into Hyperliquid's Layer-1 environment.
USDC is fully backed at a 1:1 ratio by cash and short-dated U.S. Treasuries. The reserve structure generates yield that flows back to both Circle and Coinbase under their existing revenue-sharing model.
Transfer Demonstrates Stablecoin Infrastructure Expansion
The $4 billion USDC transfer on HyperEVM demonstrates that stablecoin infrastructure is operating on networks beyond Ethereum. Circle's appointment as USDC deployer, followed by the largest USDC transfer on record, shows the arrangement moved from planning to execution. Hyperliquid has built activity in on-chain trading, and institutional participants are routing significant capital through its ecosystem when operational and compliance frameworks are established.
