Circle Internet Financial has expanded the reach of USD Coin, its dollar-backed stablecoin, by deploying native USDC and the upgraded Cross-Chain Transfer Protocol (CCTP) v2 on the Sei Network. The activation, completed on 24 July, gives Sei users direct access to USDC and lets developers move the token across 13 supported blockchains without the wrapped assets typically used in bridges. Sei, a high-speed layer-1 chain, has drawn more than 200 applications and lifted total value locked to about $600 million, a 188% increase since January. Circle said on 31 July that it will bring the same native USDC and CCTP v2 stack to Hyperliquid, a performance-focused blockchain whose ecosystem already holds roughly 70% of the USDC circulating on Arbitrum. Assets under management on Hyperliquid climbed from $4 billion to $5.5 billion in July, according to platform figures. Native integration will allow direct deposits and withdrawals of USDC and open the way for cross-chain trading, payments and treasury applications on Hyperliquid’s HyperEVM smart-contract layer. The back-to-back integrations deepen Circle’s footprint across emerging blockchains as the company prepares for a long-anticipated initial public offering. Broader native support is intended to make USDC more attractive to developers and institutions, reinforcing its position in a stablecoin market that has become a key liquidity layer for decentralized finance.
