Tether's USDT0 Launches on X Layer and OKX : Towards Unified Stablecoin Liquidity

When we launched our proprietary Layer 2 network X Layer, our goal was to solve one of Web3's most pressing issues: fragmentation.

X Layer is an Ethereum fully compatible EVM L2 that offers scalability and efficiency without sacrificing security. It seamlessly connects with OKX Wallet and OKX Trading, bringing a smooth integrated experience to millions of users. Trading is faster, costs are lower, and developers can deploy Ethereum-based applications with almost no modifications.

We call X Layer The New Money Chain because it aims to unify Web3, enabling stablecoins, tokens, and financial activities to flow smoothly across multiple networks. With the arrival of Tether's USDT0, this vision is becoming reality.

Through our partnership with Tether, we are bringing USDT0 to X Layer and the OKX platform. OKX is anchoring cross-chain stablecoin liquidity on a secure, scalable, user-friendly Layer 2 network.

USDT0 is Tether USDT's omnichain deployment version—USDT is the world's most widely used stablecoin. After USDT0 is integrated into X Layer and OKX, it not only facilitates asset transfers across multiple blockchains but also enables OKX customers to deposit and withdraw USDT0 on Arbitrum, Optimism, Polygon, Unichain, and Berachain networks through our exchange and wallet.

This integration brings USDT0 to the OKX ecosystem and broader users, unifying stablecoin liquidity across multiple of the most commonly used chains in DeFi .

Why USDT0 Matters

Stablecoins are the cornerstone of DeFi, but they remain fragmented across different chains today. Different versions of USDT exist on different Layer 2 networks , many of which are wrapped or bridged versions, which disperses liquidity and complicates user experience.

Tether's USDT0 solves this problem. Leveraging LayerZero's Omnichain Fungible Token (OFT) standard, USDT0 creates a single canonical version of USDT across supported Layer 2 networks. Every transfer is backed 1:1 by native USDT. This eliminates the need for wrapped tokens and consolidates liquidity into a single fund pool .

It also introduces compliance-oriented features such as token address freezing . This gives institutions and regulators greater confidence in on-chain stablecoin adoption.

For customers, this means:

No more need for wrapped tokens, and no need to distinguish which USDT is the "original".
Liquidity is unified across major Layer 2 networks rather than split into multiple fund pools .
Standardized USDT implementation, simplifying trading and development.
Convenient access through OKX wallet and OKX exchange .

Why X Layer Is the Ideal Destination

X Layer is not just another L2 network . It's designed as the foundation of the OKX Web3 ecosystem, deeply integrated with products trusted by millions of users. Its high-performance architecture delivers low fees and high throughput, while compatibility with Ethereum ensures developers and users can easily connect to the broader ecosystem.

The Path Forward

To truly become the cornerstone of on-chain finance, stablecoins must be simple, compliant, and accessible to everyone . With X Layer and USDT0, we're one step closer to this goal.

OKX customers can now deposit, withdraw, and transfer USDT0 on X Layer, Arbitrum, Optimism, Unichain, Berachain, and Polygon with just a few clicks.

Our vision is clear: wherever you are in Web3 , your stablecoins should be with you. And on X Layer, this vision has never been closer to reality.
