Key Takeaways:
- USDT0 by Tether is native to the Optimism and Unichain networks.
- This expansion aims to improve stablecoin accessibility and interoperability within the broader Superchain ecosystem.
- Related implementations use the ERC-7802 standard, improving interoperability and future-proofing compatibility.
Tether has launched its cross-chain dollar stablecoin, USDT0, natively on both Optimism and Unichain, expanding its reach. This is part of an effort to strengthen interoperability and offer users better choices for stablecoin use throughout the rapidly growing Superchain ecosystem. As we move into a more multi-chain world, ensuring seamless asset movement between networks is key to improving user experience and capital efficiency.
As the largest stable asset in the world with a circulation exceeding $140 billion, USD₮ now extends its presence with the introduction of USDT0, which facilitates coverage of over 96% of its total value across seven major chains, including Optimism, Unichain, Ink, Ethereum, TON, Tron, and Berachain. This integration aims to establish USDT0 as a fundamental part of the USD₮ ecosystem within the Superchain, offering users enhanced utility and efficiency.

USDT0 Launches on Optimism and Unichain
With USDT0 now natively deployed on OP Mainnet, stablecoin liquidity—instant, efficient, and omnichain-accessible—is now available on one of the fastest-growing onchain ecosystems. Optimism, the top Ethereum Layer 2 scaling solution, is behind the new Superchain, a network that aims to scale Ethereum using interoperable rollups while avoiding liquidity fragmentation.
At the same time, USDT0 has launched on Unichain, a Layer 2 network developed by Uniswap Labs using the OP Stack. Optimism’s well-established status as a leader among Layer 2 solutions, combined with Unichain’s on-demand focus on DeFi innovation, align Tether’s expansion objectives with the high-growth Superchain landscape. Unichain is designed to improve scalability and efficiency for Decentralized Finance (DeFi) applications which are perfectly suited to support USDT0’s omnichain stablecoin solution.
Bringing DeFi to the Next Level with Smooth Liquidity and Efficiency
The integration of native USDT0 will bring huge benefits to users and developers on both Optimism and Unichain. Key benefits include:
- Less Slippage: Deeper liquidity means less slippage on stablecoin swaps, opening up market efficiency.
- Efficient Transactions: Users experience seamless onchain swaps and payments with lower-cost, high-speed transactions.
- Optimized capital allocation: USDT0 provides deep liquidity and stability, serving as a reliable foundation for DeFi applications such as lending, trading, and payments. Such stable liquidity pools are particularly crucial for decentralized exchanges (DEXs) and lending protocols, which rely on them to function efficiently and offer competitive rates.
- 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. Users of the Optimism platform particularly benefit as they can move 1:1 USD₮ across any supported chain without slippage on transfers.
The introduction of USDT0 enhances liquidity within these platforms, facilitating the seamless movement of a significant portion of the $135 billion USD₮ supply across OP-supported chains.
Standardizing Superchain Stablecoin Access
In order to make all USDT0 deployments on the Superchain compatible long term and easy to cope with for developers, all USDT0 deployments are based on the ERC-7802 standard and also LayerZero compatible. Adherence enables a native, Superchain-compatible interface to USDT0 for bona fide intra-ecosystem intent without compromising on currency interoperability with the wider USDT0 network. These standards help mitigate the fragmentation and compatibility headaches that can limit ecosystem development and developer uptake.
One of the first to utilize this standardized system is Kraken’s Ink chain, which now supports USDT0 in a milestone toward unified stablecoin liquidity within Superchain. By complying with ERC-7802, USDT0 will also be future-proofed for any advancements to the validation and execution layers to come on Optimism, further solidifying USDT0 as the default stablecoin liquidity layer across all Optimism networks.
Stargate Bridging and Expanding Access
USDT0 liquidity will be natively supported on OP Mainnet, Unichain, and Ink as well as across the greater Superchain ecosystem through StargateFinance. Stargate USDT0 (Bridged) allows protocols access to stables liquidity with much of the performance benefits available right now 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.
Such an approach is particularly advantageous for emerging ecosystems within the Superchain that need access to deep liquidity now. It offers them the flexibility to build with bridged USDT0 initially and seamlessly transition to a native deployment when they mature, without needing to change contract addresses. Security is enhanced because Stargate (Bridged) USDT0 maintains a direct relationship with native USDT0 on OP Mainnet.
USDT0 is positioning itself as the de-facto stablecoin standard of the Optimism ecosystem by leveraging native deployments alongside omnichain bridging via Stargate, ensuring composable and capital-efficient liquidity across the entire ecosystem. Stablecoins like USDT0 are the system’s rails for much of the activity happening on these scaling solutions enabling trade, payments and complex financial strategies. Aiming to create a Superchain vision — an interconnected series of Ethereum Layer 2 protocols – USDT0’s strategic introduction serves as a first step toward realizing that vision by uniting L2s under a single, stable, efficient and widely accessible liquidity source to support users, developers and institutions alike as they navigate Ethereum’s evolving modular future.
