Circle expanded its stablecoin infrastructure across Plasma and Aptos through separate deployments: native USDC and EURC, the Cross-Chain Transfer Protocol (CCTP) and Bridge Kit launched on Plasma, while Aptos activated CCTP V2 on August 26. Plasma’s rollout provides native dollar and euro tokens redeemable 1:1 for U.S. dollars and euros and compliant with the European Union’s Markets in Crypto-Assets (MiCA) framework, plus fiat on- and offramp services and developer tools for payments, settlement and treasury operations. Aptos’s CCTP V2 integration connects the network with roughly nine other blockchains, including Ethereum and Solana, through more than 90 capital-efficient routes and reduces USDC settlement from minutes to seconds. CCTP burns USDC on a source chain and mints native USDC on the destination chain after Circle issues a signed attestation, avoiding wrapped tokens and bridge-based IOUs. CCTP V2 also supports programmable hooks for lending deposits, asset swaps and treasury transfers within the same flow. Circle published Plasma’s mainnet contract addresses on Aug. 28; linked Plasmascan pages showed maximum supplies of 4,654,322.737666 USDC across six holders and 12,866.64 EURC across five holders when checked. Circle lists USDC as native on 37 blockchains, EURC on eight and CCTP on 28. Aptos previously used LayerZero-routed lzUSDC, while native USDC launched on its mainnet on January 30, 2025. Enterprise users can already access USDC through Plasma One, a neobank application launched in 2025, and developers can integrate USDC and EURC into Plasma-based applications.
