Tether Expands USDT0 to Optimism, Unichain for Enhanced Liquidity

Tether has expanded its USDT0 stablecoin to the Optimism and Unichain networks, enhancing liquidity and interoperability within the broader Superchain ecosystem. This move is part of Tether's strategy to improve stablecoin accessibility and ensure seamless asset transfers, thereby boosting capital efficiency and user experience.

USDT0, which is native to both Optimism and Unichain, is now available on one of the fastest-growing onchain ecosystems. Optimism, a leading Ethereum Layer 2 scaling solution, is a key player in the Superchain network, which aims to scale Ethereum using interoperable rollups. This expansion aligns with the increasing demand for stablecoins that can operate efficiently across multiple ecosystems without liquidity fragmentation.

Unichain, developed by Uniswap Labs using the OP Stack, is another Layer 2 network that benefits from the integration of USDT0. This network focuses on DeFi innovation, making it a strategic fit for Tether's expansion objectives within the high-growth Superchain landscape.

The integration of native USDT0 brings several benefits to users and developers on both Optimism and Unichain. These include less slippage on stablecoin swaps, efficient transactions with lower costs and higher speeds, optimized capital allocation, and omnichain composability. USDT0 holders can move their digital dollars seamlessly across connected networks like Ethereum, Tron, TON, and the Superchain ecosystem, facilitated by integrations like LayerZero. This allows users of the Optimism platform to move 1:1 USD₮ across any supported chain without slippage on transfers.

To ensure long-term compatibility and ease of use for developers, all USDT0 deployments on the Superchain are based on the ERC-7802 standard and are LayerZero compatible. This adherence enables a native, Superchain-compatible interface to USDT0, mitigating fragmentation and compatibility challenges that can limit ecosystem development and developer uptake. Kraken’s Ink chain is one of the first to utilize this standardized system, supporting USDT0 in a milestone toward unified stablecoin liquidity within Superchain.

USDT0 liquidity will be natively supported on OP Mainnet, Unichain, and Ink, as well as across the greater Superchain ecosystem through Stargate Finance. Stargate USDT0 (Bridged) allows protocols access to stable liquidity with performance benefits without an immediate need for a native deployment. This progressive strategy enables emerging ecosystems to benefit from USDT0’s extensive liquidity network from the outset, promoting growth without the initial burden of complete native integration. Security is enhanced because Stargate (Bridged) USDT0 maintains a direct relationship with native USDT0 on OP Mainnet, making USDT0 the Optimism stablecoin standard and advancing the Superchain vision of unified Ethereum Layer 2s.
