Tether's USDT0 on X Layer and OKX: A Step Toward Unified Stablecoin Liquidity
When we introduced X Layer, our Layer 2 blockchain, we set out to solve one of Web3’s most pressing issues: fragmentation.
X Layer is an EVM L2 that is fully compatible with Ethereum, offering scalability and efficiency without sacrificing security. It connects seamlessly with the OKX Wallet and Exchange, creating a smooth and integrated experience for millions of customers. Transactions are faster and cheaper, and developers can deploy Ethereum-based applications with minimal changes.
We call X Layer, The New Money Chain, because it is designed to unify Web3, making stablecoins, tokens, and financial activity move seamlessly across networks. With the arrival of Tether's USDT0, that vision is becoming reality.
Through this partnership with Tether, we're bringing USDT0 to X Layer and the OKX platform, and OKX is anchoring omnichain stablecoin liquidity to a secure, scalable, and user-friendly Layer 2.
USDT0 is the omnichain deployment of Tether's USDT, the most widely used stablecoin in the world. Its integration into X Layer and OKX facilitates asset transfers across multiple blockchains allows OKX customers to deposit and withdraw USDT0 on Arbitrum, Optimism, Polygon, Unichan and Berachain through our exchange and wallet.
The integration brings USDT0 to millions more across the OKX ecosystem and beyond, unifying stablecoin liquidity across some of the most widely used chains in DeFi.
Why USDT0 Matters
Stablecoins are the backbone of DeFi, yet they remain fragmented across chains. Different versions of USDT exist on different Layer 2s. Many of them are wrapped or bridged, which divides liquidity and complicates the user experience.
Tether's USDT0 solves this problem. Powered by LayerZero’s Omnichain Fungible Token standard, USDT0 creates a single canonical version of USDT that works across supported Layer 2 networks. Each transfer is backed 1:1 by native USDT. This eliminates the need for wrapped tokens and consolidates liquidity into one pool.
It also introduces compliance-ready features such as token address freezing. This gives institutions and regulators more confidence in onchain stablecoin adoption. For customers, this means:
No wrapped tokens or confusion about which USDT is authentic.
Unified liquidity across major Layer 2s instead of fragmented pools.
A standardized implementation of USDT that simplifies trading and development.
Simple access through OKX Wallet and Exchange.
Why X Layer is the Right Home
X Layer is not just another Layer 2. It is designed to be the foundation of OKX’s Web3 ecosystem, fully integrated into the products that millions of users already trust. Its performant architecture delivers low fees and high throughput, while its Ethereum compatibility ensures builders and users can tap into the broader ecosystem with ease.
The Path Forward
Stablecoins need to be simple, compliant, and universally accessible if they are to fulfill their role as the foundation of onchain finance. With X Layer and USDT0, we are one step closer to that reality.
OKX customers can now deposit, withdraw, and transfer USDT0 across X Layer, Arbitrum, Optimism, Unichain, Berachain and Polygon in just a few clicks.
Our vision is clear: wherever you go in Web3, your stablecoin should follow you. And with X Layer, that vision feels closer than ever.
