Tether launches USDT0 omnichain stablecoin to cut blockchain fees

Tether introduced USDT0, an omnichain version of its USDT stablecoin launched in January 2025. The system locks real USDT in an Ethereum vault and mints a one‑to‑one USDT0 token on other blockchains via LayerZero’s Omnichain Fungible Token standard, avoiding bridge liquidity pools. By late 2025 more than $50 billion had been transferred through USDT0, with daily volumes in the hundreds of millions, and the token also serves as the native gas asset for Tether’s new Stable payments chain.

In parallel, Tether is developing two dedicated blockchain networks – Plasma and Stable – to reduce its dependence on external chains such as Ethereum and Tron. Plasma targets decentralized‑finance applications with its own native token and a paymaster model, while Stable is aimed at enterprises and uses USDT itself to pay transaction fees. The dual‑blockchain strategy seeks to recapture an estimated $2.9 billion in annual fees currently paid to external networks and to lower reliance on Tron, which carries about 45 % of the circulating USDT supply.
