OKX is making a bold move to change how stablecoins work by rolling out USDT0, a new unified version of USDT, across its entire platform. According to OKX on X, the update is now live on X Layer, OKX’s Ethereum Layer 2 network, as well as its wallet and exchange.
With this latest update, OKX clients now have a convenient way to deposit and withdraw USDT0 directly. It enables them to enjoy a more rich and combined liquidity pool on over 12 major chains such as Arbitrum, Optimism, Polygon, Berachain, and Unichain.
In an explanation, OKX said that USDT0 is driven by LayerZero’s Omnichain Fungible Token (OFT) standard, where all trades are verifiably settled and 1:1 backed by canonical USDT.
Furthermore, it eliminates wrapped tokens and perilous bridging solutions. Hence, it is a more secure and efficient way of transferring stablecoins between decentralized finance (DeFi) networks.
The integration allows instant settlements and direct liquidity flows between OKX’s centralized exchange and decentralized markets. Besides, it boosts the speed of cross-rollup transactions while reducing friction for traders and developers.
Star Xu, OKX’s founder and CEO, described X Layer as “The New Money Chain and a foundation for seamless, stable, and interoperable value exchange.” He added, “By partnering with Tether to bring USDT0 to X Layer and other chains, we’re empowering customers with stable omnichain liquidity.”
Since its launch, USDT0 has processed over $11.3 billion in bridge volume through more than 251,000 cross-chain transfers, making it the most active OFT in the LayerZero ecosystem.
Lorenzo R., USDT0 co-founder, emphasized its impact: “Stablecoins are becoming the backbone of on-chain finance. With USDT0 live on OKX and X Layer, millions can tap into unified liquidity.”
Additionally, Tether plans to launch USDT on RGB, a new protocol that expands Bitcoin’s role beyond a store of value. This shows the growing vision for stablecoins to power the next generation of global finance.
