Coinbase is expanding its role within the Hyperliquid ecosystem by taking on responsibility for managing USDC liquidity across the rapidly growing decentralized trading platform.

The company said Thursday it will act as the official treasury deployer of USDC on Hyperliquid (HYPE), marking a deeper integration into one of crypto’s most active onchain derivatives markets.

Under the agreement, Coinbase (COIN) will oversee stablecoin liquidity through Hyperliquid’s Aligned Quote Asset (AQA) framework. The system embeds USDC directly into the platform’s trading infrastructure while directing reserve yield revenue back to the protocol.

As part of the transition, Native Markets—the developer of Hyperliquid’s native stablecoin USDH—has agreed to terms granting Coinbase the option to acquire USDH brand assets. USDH will remain redeemable for USDC or fiat during a phased migration before being gradually retired.

The move reinforces Coinbase’s broader effort to drive USDC adoption beyond Ethereum (ETH) and centralized exchanges, even as competition among stablecoin issuers continues to intensify.

Hyperliquid has quickly become one of the most closely watched decentralized finance trading platforms, known for its low fees, deep liquidity, and performance that rivals centralized exchanges.

Trading activity on the network has accelerated in recent months as users increasingly migrate to onchain markets amid renewed interest in DeFi. Coinbase estimates USDC supply on Hyperliquid has roughly doubled year over year, reaching about $5 billion.

The platform has also grown into a key venue for speculative trading and token launches, further elevating its role in broader crypto market structure debates. Because stablecoins serve as the primary settlement layer for digital asset trading, deeper integration within a fast-scaling exchange ecosystem enhances distribution for both Coinbase and Circle (CRCL).

Native Markets said Coinbase’s participation could further strengthen Hyperliquid’s expansion by bringing a major U.S. crypto company deeper into its ecosystem.

The partnership also reflects a wider evolution in crypto infrastructure, where stablecoins are increasingly embedded into trading, collateral, and treasury systems rather than treated as standalone assets.

Separately, Circle (CRCL), the issuer of USDC, announced an expanded role within Hyperliquid as USDC becomes the Aligned Quote Asset across HIP-1 through HIP-4 markets. HIP-4 introduces outcome-based markets, extending the platform beyond perpetual futures.

Circle will also handle technical responsibilities for USDC deployment on Hyperliquid, including minting, redemption, and cross-chain transfers, positioning USDC as the core settlement layer across the exchange’s expanding market structure.
