Hyperliquid has linked USDC between its Layer 1, HyperCore, and its HyperEVM, enabling secure, natively minted cross-chain USDC deposits. This marks a significant milestone in the platform's goal to create a unified liquidity ecosystem.

In its final state, the integration will deprecate the existing Arbitrum bridge, meaning all USDC on the platform will be natively minted through Circle's Cross-Chain Transfer Protocol (CCTP). This removes reliance on third-party bridges, enhancing security and streamlining the movement of assets.

Key Features of the Update:

• One-Click Deposits: HyperCore now supports seamless, one-click USDC deposits from CCTP-enabled chains, automatically handling minting on HyperEVM.
• No Immediate Changes for Users: Deposits and withdrawals remain available via both the Arbitrum bridge and HyperEVM. There are no breaking changes.
• Transition Phase Notes: During this period, transfers from HyperCore to HyperEVM may occasionally fail if HyperEVM lacks sufficient liquidity (funds remain safe in HyperCore). Users can fall back to the Arbitrum bridge for withdrawals.
• Improved User Experience: CCTP enables single-transaction transfers to and from HyperCore across supported chains. Circle has already deployed the CCTP route from Arbitrum, with more chains incoming.

Builders are encouraged to begin migrating integrations to the new HyperEVM USDC deposit flow, as the contracts now support enhanced cross-chain functionality.

This development builds on Hyperliquid's earlier native USDC rollout on HyperEVM (September 2025) and further solidifies its position as a leading DeFi ecosystem, combining CEX-like performance with on-chain composability.
