In an unprecedented move, Circle shifted roughly $4.4 billion worth of USDC to a Coinbase wallet through the HyperEVM network. Blockchain analytics firm Arkham identified this as the largest USDC transaction in history. The transfer, comprising about 4.397 billion USDC, was directed to an address linked to Coinbase.
This massive transaction stands out due to its sheer scale and the route taken. HyperEVM is part of the Hyperliquid ecosystem, where USDC serves as a critical asset for trading, quoting, and settlement. Arkham highlighted the significance of this transfer, noting its record-breaking size.
The move appears tied to Coinbase’s recent designation as Hyperliquid’s official USDC treasury deployer under the Aligned Quote Asset (AQA) framework. In May, Coinbase announced expanded support for USDC on Hyperliquid, aiming to enhance the stablecoin’s role in onchain capital markets. By consolidating liquidity around USDC, the system could streamline market operations and reduce conversion needs.
USDC had already become the dominant stablecoin on Hyperliquid, with its supply reaching approximately $5 billion and doubling year-over-year. This context suggests that the large transfer is part of a broader treasury and liquidity strategy rather than a typical exchange deposit. Neither Circle nor Coinbase had publicly commented on this specific transaction at the time of reporting.
The Coinbase-Hyperliquid partnership also impacts USDH, the native stablecoin of the Hyperliquid ecosystem. Coinbase stated that Native Markets, the entity behind USDH, has agreed to terms allowing Coinbase to acquire USDH brand assets. While USDH markets remain operational for now, they are expected to be phased out gradually. Users can still convert USDH to USDC fee-free or redeem it for fiat during the transition period.
Hyperliquid has also designated Circle as the technical deployer for Cross-Chain Transfer Protocol (CCTP) and native cross-chain infrastructure. Coinbase manages the USDC treasury side, while Circle ensures seamless USDC movement across different blockchains. Earlier reports from crypto.news noted that Hyperliquid had already achieved record trading volumes before this treasury shift. The integration of Circle’s native USDC and CCTP V2 is anticipated to facilitate direct on and off ramps, cross-chain transfers, and improved liquidity for decentralized finance (DeFi) and derivatives markets.
This record transfer shines a spotlight on stablecoin flows within major onchain trading venues. USDC is extensively used for collateral, settlement, and quote markets, meaning large treasury movements can significantly influence liquidity dynamics.
