Today we are thrilled to announce that USDT0 is expanding to Optimism and Unichain, bringing USD₮ to the Superchain.

USD₮ has reshaped entire global economies and is the largest stable asset in the world, at over $140B+. And with Optimism and the Superchain added to the USDT0 ecosystem, over 96% of all USD₮ in circulation is now connected across seven chains: Optimism, Unichain, Ink, Ethereum, TON, Tron, and Berachain.

At the same time, Stargate USDT0 (Bridged) now expands liquidity across other Superchain rollups, with integrations like USDT0 on Ink ensuring interoperability within the OP ecosystem’s broader liquidity landscape.

Your USD₮0, anywhere—as the canonical USD₮ across the entire Superchain and beyond.

Optimism is one of the leading EVM L2s and creator of the Superchain, a growing universe of interoperable rollups designed to scale Ethereum without liquidity fragmentation.

With USDT0 now natively deployed on OP Mainnet, we’re bringing instant, efficient, and omnichain-accessible stablecoin liquidity to one of the fastest-growing onchain ecosystems. This enables seamless, capital-efficient stablecoin transactions moving via LayerZero across everything Optimism touches, with USDT0 legacy mesh connecting Optimism to Tron, TON, and Berachain.

As a result, Optimism users now benefit from:

• 1:1 USD₮ movement across Optimism’s DeFi ecosystem, with no slippage on transfers between chains.

• Deep liquidity for lending, trading, and payments, providing a stable, capital-efficient foundation for DeFi applications.

• Seamless omnichain composability, allowing USDT0 holders to move digital dollars across Ethereum, Tron, TON, and the Superchain ecosystem.

With this, over $135B of USD₮ can now be seamlessly transferred between OP-supported chains. The end result is a rapidly growing ecosystem that is further augmented with the most efficient, secure, and scalable stablecoin infrastructure available.

USDT0 is also expanding to Unichain, the L2 developed by Uniswap Labs and built on the OP Stack. Unichain is designed to enhance scalability and efficiency for DeFi applications, which makes it a perfect fit for USDT0’s omnichain stablecoin solution.

With USDT0 now natively deployed on Unichain, the chain gains:

• Optimized stablecoin liquidity for a wide range of DeFi dApps and activities, reducing slippage and improving market efficiency.

• Lower-cost, higher-speed stablecoin transactions, making onchain swaps and payments more seamless than ever.

To future-proof interoperability, all USDT0 deployments across the Superchain are ERC-7802 and LayerZero compatible. This gives developers a native, Superchain-aligned way to interact with USDT0 for intra-Superchain transfers, while preserving full compatibility with the broader USDT0 ecosystem.

Kraken’s Ink is among the first chains to integrate USDT0 within this system, marking a key milestone in standardized stablecoin liquidity across the Superchain. As Optimism continues to advance its native interoperability framework, ERC-7802 ensures that USDT0 remains fully compatible with upcoming validation and execution models, strengthening USDT0’s position as the default stablecoin liquidity layer across Optimism-powered networks.

While OP Mainnet, Unichain, and Ink now feature native USDT0, the expansion doesn’t stop there. USDT0 is also available across the wider Superchain ecosystem through Stargate USDT0 (Bridged), enabling rollups and protocols to access stablecoin liquidity without requiring a native deployment upfront.

This is particularly beneficial for ecosystems that are not yet mature enough for a native deployment, but are ready to leverage USDT0’s Stargate-powered liquidity model. This allows emerging Superchain rollups to build liquidity with bridged USDT0 while maintaining the flexibility to seamlessly transition to a native deployment when ready, without ever needing to change contract addresses. All Stargate (Bridged) USDT0 is backed by USDT0 on OP Mainnet, offering a secure connection point between this new version and native USDT0 deployments.

By integrating both native deployments and omnichain bridging, USDT0 is establishing itself as the stablecoin standard for the Optimism ecosystem, ensuring composable, capital-efficient liquidity across the entire Superchain network.

Optimism’s Superchain vision continues to transform Ethereum’s scalability landscape, moving beyond fragmented L2s toward a unified network of interoperable rollups. With USDT0 now natively deployed on OP Mainnet, Unichain and Ink and seamless bridging available across all Superchain rollups, the foundation for stable, efficient, and composable liquidity is stronger than ever.

As Ethereum’s modular future unfolds, USDT0 ensures that users, developers, and institutions can transact with stable, omnichain-accessible liquidity, wherever they are active.
