Circle Launches Native USDC and Cross-Chain Transfer Protocol on OKX's X Layer
Key Takeaways
- •Circle has launched natively issued USDC and its Cross-Chain Transfer Protocol on X Layer, OKX's Ethereum layer-2 scaling network.
- •CCTP enables cross-chain USDC transfers through a burn-and-mint mechanism that avoids wrapped tokens and liquidity pools, reducing counterparty risk.
- •With this deployment, native USDC is available on 36 blockchains and CCTP operates across 26 networks.
- •The expansion follows OKX Europe's introduction of a USDT-to-USDC conversion tool as the exchange adjusts to the EU's MiCA regulatory requirements.
- •USDC satisfies MiCA compliance standards and has become a primary stablecoin alternative for European users under the new regulatory regime.
Circle has launched native USDC and its Cross-Chain Transfer Protocol (CCTP) on X Layer, OKX's Ethereum layer-2 network, providing users and developers direct access to Circle-issued USDC without dependence on bridged or wrapped tokens. Bridged stablecoins have historically been a recurring vector for exploits and de-peg events, making native issuance increasingly preferred by DeFi protocols and exchanges seeking to minimize smart-contract and liquidity risk.
CCTP facilitates USDC transfers between X Layer and other supported blockchains through a burn-and-mint mechanism: USDC is burned on the source chain and an equivalent amount is freshly minted on the destination chain. This approach eliminates the need for wrapped assets or conventional liquidity pools, reducing counterparty risk and improving capital efficiency. For developers building on X Layer, the integration means USDC can be embedded in smart contracts with the same reserve backing as USDC on Ethereum mainnet, with substantially lower gas costs typical of layer-2 networks.
With this integration, native USDC is now available across 36 blockchains, while CCTP operates on 26 networks. The expansion reinforces USDC's position as foundational infrastructure for cross-chain payments, decentralized finance (DeFi), trading, and automated transactions involving AI agents.
The deployment follows a recent move by OKX Europe, which introduced a feature enabling users to convert Tether's USDT into Circle's USDC as the exchange continues adapting to the European Union's Markets in Crypto-Assets (MiCA) regulatory framework. USDC is among the stablecoins that satisfy MiCA's compliance requirements and has emerged as one of the primary alternatives available to European users navigating the new regulatory landscape. MiCA, which began phased implementation in 2024, introduced some of the world's first comprehensive rules for crypto-asset issuers and service providers, prompting major exchanges to adjust their stablecoin offerings across the bloc.
