Tether's USDT0 went live on the Stellar network on September 2, connecting the payments-focused blockchain to more than $180 billion in USDT liquidity. The deployment gives Stellar users access to a unified version of Tether's dollar stablecoin that operates consistently across multiple blockchain ecosystems.

The integration is aimed at payments, remittances, treasury operations, and decentralized finance (DeFi). USDT0 is built on LayerZero's Omnichain Fungible Token standard, which enables cross-chain transfers without depending on traditional custodial bridges or generating separate wrapped-token pools. That design addresses a well-known pain point in cross-chain finance: custodial bridges have repeatedly been exploited, with industry trackers attributing billions of dollars in losses to bridge hacks in recent years.

Unified Liquidity Across Networks

USDT0 maintains a single token supply backed 1:1 by USDT, while allowing that liquidity to move freely across supported networks. The design is intended to reduce fragmentation and make USDT simpler to use across different blockchain environments.

Since launching in January 2025, USDT0 has facilitated more than $100 billion in value transfers. According to the companies involved, the network now supports more than 20 blockchain ecosystems.

For Stellar, the addition of USDT0 provides access to the stablecoin that dominates many emerging-market payment corridors. Stellar offers sub-cent transaction costs and transaction finality in roughly five seconds, aligning with its focus on cross-border financial applications. Stellar has long positioned itself around real-world payment use, including its work with MoneyGram on cash-to-crypto services.

New Options for DeFi and Payments

The launch also broadens Stellar's potential for stablecoin-based financial products. Within DeFi, USDT0 can function as collateral, a trading asset, and a source of liquidity for lending and other applications.

At launch, USDT0 is available through several exchanges, wallets, custody providers, and financial platforms. SushiSwap is among the initial DeFi integrations, and additional services are expected to join the ecosystem.

The integration may prove especially relevant in Latin America, Africa, and Asia-Pacific, regions where USDT already plays a major role in dollar-based digital payments and settlement. It also arrives amid a fast-moving regulatory environment for stablecoins: the EU's Markets in Crypto-Assets (MiCA) framework took full effect in late 2024, and the United States enacted federal stablecoin legislation in 2025, developments that have sharpened institutional attention on compliant, interoperable dollar tokens.

By combining Stellar's low-cost payment infrastructure with USDT's broad liquidity base, USDT0 offers businesses and developers a way to move dollar liquidity across networks with fewer conversion and integration hurdles. The launch accordingly reinforces Stellar's position as infrastructure for cross-border stablecoin payments and on-chain financial services. Further expansion of USDT0 to additional networks, and the pace of DeFi and custody integrations, will indicate how broadly the omnichain model is adopted.
