Tether has launched USDT0, an omnichain version of its USDT stablecoin, on Optimism's Superchain, enhancing the availability of this widely used asset in Ethereum's layer-2 ecosystem.

USDT0 is a bridged version of Tether's existing USDt, designed to expand its adoption across multiple blockchains.

This stablecoin aims to facilitate interblockchain compatibility and enhance interoperability within the Superchain ecosystem.

The deployment of USDT0 will utilize native Superchain interoperability, enabling frictionless asset movement with 1-block finality and zero slippage.

The introduction of USDT0 is expected to foster growth in decentralized finance (DeFi) by allowing capital to move freely and enabling barrier-free transactions.

Furthermore, the deployment of USDT0 is anticipated to attract more significant assets, applications, and partners, highlighting the crucial role stablecoins play in DeFi adoption.

Currently, the Superchain accounts for nearly half of all Ethereum Layer 2 transactions and is utilized by major companies such as Coinbase, Kraken, Uniswap, and Sony.

Since February 2025, Superchain has increased its total value from over $4 billion to $4.2 billion, indicating heightened activity and investment in the ecosystem.

The total value of stablecoins in circulation has risen to nearly $228 billion, with Ethereum comprising 58% of this total stablecoin supply.

Tether remains a dominant player in the stablecoin market and is one of the largest holders of US Treasury assets, contributing to its substantial profits.

With the current U.S. administration, dollar-pegged stablecoins have become a focal point for regulatory discussions, with comprehensive regulations expected to be proposed soon.

Everdawn Labs manages USDT0, which is fully backed by Tether, the largest stablecoin by market capitalization, though it is not directly managed by Tether itself.
