Cross-chain infrastructure is gaining prominence as stablecoins scale beyond single networks. Wormhole, a multichain interoperability platform, shared on social media platform X on Dec. 15 information following Ripple’s disclosure, outlining how stablecoin Ripple USD (RLUSD) will expand across Ethereum Layer 2 ecosystems using Wormhole’s Native Token Transfers standard.

Wormhole shared on social media platform X:

Ripple’s $1.3b stablecoin, RLUSD, has adopted Wormhole’s NTT standard to expand multichain. This integration will enable the issuance of RLUSD across all of crypto, starting with Base, Optimism, Ink, and Unichain. NTT is the standard for multichain asset issuance.

The post described how Native Token Transfers allow RLUSD to move across networks while remaining natively issued, rather than relying on wrapped representations that fragment liquidity. Ripple designed RLUSD to originate on the XRP Ledger and Ethereum, with Layer 2 networks serving as scalable environments for decentralized finance, payments, and institutional use cases. Wormhole emphasized that the integration allows Ripple to maintain direct control over issuance and smart contracts while benefiting from permissionless cross-chain connectivity.

“Testing will begin on Optimism, Base, Ink, and Unichain, in partnership with Wormhole—one of the leading multichain interoperability protocols—and its NTT token standard,” Ripple noted.

Further details were provided in a separate X post. The platform explained:

With NTT, token issuers eliminate the need for fragmented liquidity or wrapped assets, allowing a single, canonical version of RLUSD to exist natively on each blockchain with Ripple owning the contracts.

“Interoperability is a critical need for major asset issuers. By choosing Wormhole, a permissionless protocol used by institutions like Blackrock, Vaneck and Apollo Global, Ripple ensures it has the best interoperability infrastructure to grow RLUSD multichain,” Wormhole added.

RLUSD operates under a New York Department of Financial Services Trust Company Charter, offering bank-level oversight designed to support enterprise adoption. Ripple has also received conditional approval for an Office of the Comptroller of the Currency (OCC) charter, which would introduce federal supervision alongside state regulation. Wormhole supports more than 40 blockchain networks and has facilitated over $70 billion in cross-chain transfers, positioning its infrastructure as a core layer for compliant, scalable stablecoin issuance in an increasingly multichain crypto market.

• What role does Wormhole play in RLUSD expansion?
  Wormhole provides the NTT standard enabling RLUSD to move natively across multiple blockchains.
• Why is Native Token Transfers important for RLUSD?
  NTT avoids wrapped assets, keeping a single canonical version of RLUSD on each network.
• Which networks will RLUSD expand to first?
  RLUSD is launching across Ethereum Layer 2 networks including Base and Optimism.
• How is RLUSD regulated?
  RLUSD operates under a New York Department of Financial Services Trust Company Charter.
