When we launched our own Layer 2 network, X Layer, our goal was to tackle one of Web3’s most pressing issues: fragmentation.

X Layer is an Ethereum-compatible EVM L2 that offers scalability and efficiency without sacrificing security. It’s seamlessly connected to the OKX Wallet and OKX exchange, bringing a smooth, unified experience to millions of users. Transactions are faster and cheaper, and developers can deploy their Ethereum-based apps with minimal changes.

We call X Layer The New Money Chain because it’s designed to unify Web3, enabling stablecoins, tokens, and financial activity to flow smoothly across networks. With the arrival of Tether’s USDT₀, that vision is becoming a reality.

Through our collaboration with Tether, we’re bringing USDT₀ to X Layer and the OKX platform, anchoring omnichain stablecoin liquidity on a secure, scalable, and user-friendly L2.

USDT₀ is the omnichain deployment of Tether’s USDT — the world’s most widely used stablecoin. By integrating USDT₀ on X Layer and OKX, we’re facilitating asset transfers across multiple blockchains and enabling OKX customers to deposit and withdraw USDT₀ on Arbitrum, Optimism, Polygon, Unichain, and Berachain via our exchange and wallet.

This integration brings USDT₀ to the OKX ecosystem and beyond, unifying stablecoin liquidity across some of the most used chains in DeFi.

Why USDT₀ Matters？

Stablecoins are the backbone of DeFi, but they’re still fragmented across chains. Different versions of USDT exist on various L2s — many of which are wrapped or bridged — which fractures liquidity and complicates the user experience.

Tether’s USDT₀ solves this. Using LayerZero’s Omnichain Fungible Token (OFT) standard, USDT₀ creates a single canonical version of USDT across supported L2s. Every transfer is backed 1:1 by native USDT. This eliminates the need for wrapped tokens and consolidates liquidity into a single pool.

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

For customers, this means:

• No more wrapped tokens or guessing which USDT is the “real” one.

• Unified liquidity across major L2s instead of fragmented pools.

• A standardized implementation of USDT that simplifies trading and development.

• Easy access via the OKX Wallet and OKX exchange.

Why X Layer Is the Ideal Home？

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

The Road Ahead

For stablecoins to truly become the backbone of on-chain finance, they must be simple, compliant, and accessible to all. With X Layer and USDT₀, we’re one step closer.

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

Our vision is clear: no matter where you are in Web3, your stablecoins should be there with you. And on X Layer, that vision is closer than ever.
