- Circle has replaced bridged USDC with native USDC on X Layer.
- The upgrade introduces CCTP, enabling secure burn-and-mint cross-chain USDC transfers.
- X Layer gains direct access to Circle-issued liquidity, reducing reliance on third-party bridges.
Circle has expanded native USDC to X Layer, replacing the network’s bridged version of the stablecoin and giving the OKX-linked blockchain direct access to Circle-issued dollar liquidity.
The rollout also brings Circle’s Cross-Chain Transfer Protocol (CCTP) to X Layer, allowing USDC to move between supported blockchains through a native burn-and-mint mechanism rather than relying on conventional third-party bridges.
The change is significant for X Layer because the network previously relied on bridged USDC infrastructure to establish dollar liquidity. Circle describes bridged USDC as a third-party-issued representation backed by USDC locked on another blockchain, while native USDC is issued directly by Circle and redeemable 1:1 for US dollars.
We’re replacing USDC_Bridged with native @USDC on X Layer.
Issued by regulated affiliates of @Circle, fully reserved, 1:1 redeemable, CCTP-ready, and MiCA-compliant.

X Layer moves from bridged to native USDC
X Layer had previously adopted Circle’s Bridged USDC Standard, which was specifically designed to give newer blockchains an initial source of USDC liquidity while preserving a pathway toward eventual native issuance.
Under that model, ownership of a compliant bridged USDC contract can be transferred to Circle and upgraded without requiring developers to replace integrations or users to manually swap into an entirely different token. Circle previously demonstrated the process with Linea, where roughly 500,000 wallets and $21 million in USDC liquidity were transitioned through its first bridged-to-native upgrade.
For X Layer, native issuance removes the additional bridge structure between the stablecoin circulating on the network and Circle itself.
The distinction matters because bridged USDC depends on USDC being locked elsewhere, whereas native USDC represents a direct Circle liability backed by the reserves supporting the broader stablecoin.
CCTP reduces dependence on third-party bridges
CCTP adds another important component to the rollout.
Instead of locking USDC on one blockchain and issuing a wrapped representation on another, CCTP burns native USDC on the originating network and authorizes an equivalent amount to be minted on the destination chain.
That model reduces liquidity fragmentation between different representations of the same stablecoin and gives developers a standardized method for moving dollar liquidity between supported networks. Circle also notes that bridged USDC itself is not compatible with CCTP, making native issuance necessary to unlock that interoperability.
The upgrade comes as bridge security has become an increasingly important consideration across crypto. Recent high-profile exploits and migrations between interoperability providers have pushed developers toward infrastructure that minimizes wrapped assets and bridge-held liquidity.
Circle widens USDC’s multichain footprint
X Layer adds another network to Circle’s rapidly expanding stablecoin infrastructure.
As of May, Circle listed native USDC support across 34 blockchain networks, including Ethereum, Solana, Base, Arbitrum, Avalanche, Polygon, XRP Ledger, HyperEVM, Linea and XDC.
The expansion also comes as USDC itself continues growing. Circle reported $73.3 billion of USDC in circulation at the end of the second quarter, up 19% year over year, while onchain transaction volume increased 151%.
For X Layer, the upgrade provides a more direct settlement asset as it expands into payments, DeFi and tokenized markets. For Circle, it continues a broader strategy of replacing fragmented bridged dollar liquidity with directly issued USDC connected through its own cross-chain infrastructure.
