Coinbase has announced its plan to activate AQAv2 on USDC as the treasury deployer, with Circle serving as the technical deployer responsible for CCTP and native cross-chain infrastructure. Both Coinbase and Circle have committed to stake HYPE to activate AQAv2. As part of this transition, Native Markets has agreed to terms granting Coinbase the right to purchase the USDH brand assets. 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. As a result, canonical outcome (HIP-4) markets will use USDC as the quote asset in a future network upgrade. User and builder feedback has been consistent that fragmentation leads to degraded experience; now, the community no longer needs to choose between liquidity and protocol alignment. 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. The Hyper Foundation will give grants to eligible HIP-3 deployers, HIP-1 deployers, and builders who integrated USDH, supporting teams through migration over the next months. These grants reflect an ongoing commitment to teams who choose to build on Hyperliquid and align with the protocol. USDH markets are fully functional but will sunset over time. USDH remains fully backed, with feeless conversions to USDC and fiat available to users during this transition.
