Crypto exchange OKX has announced a strategic partnership with Tether to launch USDT0, a bridged variant of the USDT stablecoin, on X Layer – OKX’s Ethereum Layer 2 network – with full integration across OKX Wallet and OKX Exchange.
Through this collaboration, users can now deposit and withdraw USDT0 directly via OKX platforms, while gaining access to unified liquidity across major DeFi ecosystems, including Arbitrum, Optimism, Unichain, Polygon, and Berachain.
USDT0 is built on LayerZero’s Omnichain Fungible Token (OFT) standard, ensuring each transaction is transparent, verifiable, and backed 1:1 with canonical USDT. To date, the system has processed more than $11 billion in cross-chain transaction volume across over 251,000 transfers spanning nine blockchain pathways.
According to Lorenzo R., co-founder of USDT0, integrating the stablecoin into X Layer and the OKX ecosystem unlocks scalable, cross-chain liquidity while addressing fragmentation in stablecoin usability:
“Stablecoins are becoming the backbone of on-chain finance. With USDT0 now live on OKX and X Layer, millions of users and builders can access unified, cross-chain liquidity at scale.”
OKX founder Star Xu highlighted that the integration marks an important step toward positioning X Layer as a foundational network for seamless and interoperable value exchange:
“By partnering with Tether to bring USDT0 to X Layer and other chains within the OKX ecosystem, we’re empowering our users with stable omnichain liquidity across the networks they rely on most, bridging centralized and decentralized finance faster, easier, and more intuitively than ever before.”
OKX launched X Layer last April to reduce transaction costs and enhance scalability. The network supports multiple decentralized applications and uses OKB tokens as gas fees.
Notably, OKB has recently experienced a sharp price surge following OKX’s announcement of a comprehensive tokenomics overhaul, including the burning of more than 65 million tokens. This move is expected to further strengthen X Layer’s role in DeFi and broader global applications.
