OKX and Tether have partnered to bring USDT0, a bridged variant of Tether’s USDT, to X Layer, OKX’s Ethereum layer 2 network, along with full support in OKX Wallet and Exchange, the companies announced Tuesday.
The integration enables users to deposit and withdraw USDT0 directly through OKX’s platforms, accessing unified liquidity across multiple DeFi ecosystems, including Arbitrum, Optimism, Unichain, Polygon, and Berachain.
Built on LayerZero’s Omnichain Fungible Token standard, USDT0 ensures each transfer is verifiable and maintains a 1:1 backing with canonical USDT. The system has processed over $11 billion in bridge volume across more than 251,000 cross-chain transfers, supporting nine chain pathways.
Lorenzo R., co-founder of USDT0, said that bringing the stablecoin to OKX’s platform and L2 network, X Layer, helps unlock scalable, cross-chain liquidity. The move aims to bridge fragmentation in stablecoin usability and provide seamless access to value across multiple ecosystems.
“Stablecoins are becoming the backbone of onchain finance. With USDT0 live on OKX and X Layer, millions of users and builders can tap into unified, cross-chain liquidity at scale,” he stated.
According to OKX founder Star Xu, the integration of USDT0 marks a 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 across the OKX platform, we’re empowering our customers with stable omnichain liquidity across the networks they rely on most, while bridging centralized and decentralized finance faster, easier, and more intuitively than ever before,” Xu noted.
OKX launched X Layer last April in a bid to reduce transaction costs and enhance scalability. The network supports multiple decentralized applications and utilizes OKB tokens for gas fees.
OKB recently experienced a massive price surge after the crypto exchange announced a comprehensive tokenomics overhaul, including the burning of over 65 million tokens. The overhaul aims to strengthen X Layer in DeFi and other global applications.
