OKX's integration of USDT0 on X Layer brings unified liquidity, streamlining stablecoin transfers and boosting DeFi composability across multiple chains.

OKX, USDT, and X Layer: Leveling Up DeFi with Unified Liquidity
OKX is partnering with Tether to bring USDT0 onto X Layer, OKX’s Ethereum Layer 2 network, as well as to the OKX Wallet and Exchange. This unlocks composable liquidity across DeFi. Let's dive into what this means for the future of decentralized finance.
The Skinny on USDT0 and X Layer
OKX has teamed up with Tether to integrate USDT0, a unified liquidity solution for USDT, across its Ethereum Layer-2 X Layer, the OKX Wallet, and the OKX exchange. This rollout aims to bring unified, composable stablecoin liquidity to OKX's massive user base. The integration allows users to deposit and withdraw USDT0 directly through the OKX wallet and Exchange, accessing deeper stablecoin liquidity across networks like Arbitrum, Optimism, Unichain, Polygon, and Berachain.
Omnichain Transfers: Eliminating the Friction
USDT0 leverages LayerZero’s Omnichain Fungible Token (OFT) standard. Every transfer is verifiable and backed 1:1 by canonical USDT, ensuring transparency and eliminating the need for wrapped tokens and bridging solutions. This integration speeds up settlement, simplifies cross-rollup movement, and allows users to move liquidity between OKX’s centralized venue and decentralized markets seamlessly.
X Layer: The New Money Chain
OKX's founder and CEO, Star Xu, describes X Layer as “The New Money Chain and a foundation for seamless, stable, and interoperable value exchange.” This Layer 2 network is fully integrated across OKX’s product suite, providing a streamlined and secure user experience.
By partnering with Tether to bring USDT0 to X Layer and other chains across the OKX platform, customers now have stable omnichain liquidity across networks. This integration bridges centralized and decentralized finance faster, easier, and more intuitively than before.
Rapid Growth and Market Impact
In less than a year since its launch, USDT0 has processed over $11.3 billion in bridge volume across more than 251,000 cross-chain transfers, supporting nine chain pathways. This makes it the most active OFT within the LayerZero ecosystem.
Lorenzo R., co-founder of USDT0, emphasizes that stablecoins are becoming the backbone of on-chain finance. With USDT0 live on OKX and X Layer, millions of users and builders can tap into unified, cross-chain liquidity at scale.
Future Expansion: USDT on Bitcoin
Tether plans to launch USDT on RGB, a next-generation protocol for issuing digital assets on Bitcoin. This move is designed to expand Bitcoin’s role beyond a store of value, allowing stablecoins to exist natively on Bitcoin’s blockchain.
Final Thoughts
OKX’s integration of USDT0 on X Layer is a big step towards mainstream adoption of stablecoins in global finance. By removing the friction associated with stablecoin transfers and providing unified liquidity across multiple chains, OKX is positioning itself as a key player in the DeFi space. So, buckle up, folks—the future of finance is looking brighter and a whole lot smoother!
