Coinbase Becomes USDC Treasury Deployer on Hyperliquid as Native Stablecoin USDH Winds Down

Announced Thursday, the arrangement places Coinbase at the center of USDC’s reserve management on Hyperliquid, with Circle handling the technical side through its Cross-Chain Transfer Protocol. The agreement also gives Coinbase the right to purchase the brand assets of USDH, the native stablecoin issued by Native Markets that launched on Hyperliquid in September 2025.

Hyperliquid described the move in a statement on X: “With Coinbase, in its role as treasury deployer, sharing the vast majority of reserve yield revenue with the protocol, USDC will become the most aligned stablecoin on Hyperliquid.”

USDC has been Hyperliquid’s dominant collateral since the platform launched in 2023. Supply on the network has grown to roughly $5 billion, about double what it was a year ago, making Hyperliquid one of the most concentrated environments for on-chain dollar usage in derivatives trading.

The AQAv2 upgrade names USDC as the canonical quote asset for future markets under Hyperliquid’s HIP-4 specification. Both Coinbase and Circle have committed to stake HYPE tokens to activate the framework. Coinbase has also increased its staked HYPE position beyond what the activation requires.

Coinbase described the integration in a blog post published the same day: “As 24/7 onchain capital markets grow, concentrating liquidity with USDC, which is always available and instantly transferable, improves market efficiency and allows capital to flow freely with fewer conversions.”

The agreement effectively resolves a tension that has existed on Hyperliquid since USDH launched. Traders and builders could access deeper liquidity through USDC, but only USDH carried the yield-sharing mechanics that kept reserve income inside the protocol. AQAv2 folds that yield-sharing directly into the USDC integration, removing the tradeoff.

Hyperliquid acknowledged the groundwork laid by Native Markets: “The pioneering work of Native Markets in launching USDH as the first production-scale stablecoin sharing yield directly with a protocol in a purely onchain implementation made AQAv2 possible. The learnings and mechanics pioneered by USDH will live on in AQAv2.”

USDH markets remain fully operational during the transition. Native Markets’ USDH Dashboard gives users feeless conversion from USDH to USDC, along with fiat redemption options. Coinbase noted in its blog post that “users will continue to be able to redeem USDH for USDC or fiat without fees via Native Markets’ USDH Dashboard” over the coming months.

The Hyper Foundation is providing grants to eligible HIP-3 deployers, HIP-1 deployers, and builders who integrated USDH to cover migration costs. Hyperliquid said those grants “reflect an ongoing commitment to teams who choose to build on Hyperliquid and align with the protocol.”

For traders using Hyperliquid, the practical result is a single stablecoin across all major markets, deeper liquidity in USDC-quoted pairs, and direct access to Coinbase’s global fiat on and off-ramp infrastructure. Cross-chain movement is handled natively through CCTP, removing friction for users bridging in from other networks.

For Coinbase and Circle, the deal extends USDC’s reach into one of the most active on-chain trading venues. Coinbase framed the moment in broader terms: “This integration solidifies USDC’s role as the preferred stablecoin underlying onchain capital markets.”

The Hyperliquid ecosystem benefits in a way that mirrors what USDH originally promised but with the liquidity advantage USDC already carries. Reserve yield that previously flowed to external issuers now returns to the protocol, supporting HYPE buybacks and the Assistance Fund, with a larger supply base generating that yield than USDH ever reached.
