USD₮0 (ticker: USDT0) is an omnichain deployment of Tether’s USD₮ that allows the asset to move natively across multiple blockchains via LayerZero’s Omnichain Fungible Token (OFT) standard. In this model, USD₮ on a source chain (typically Ethereum) is locked, and an equivalent amount of USDT0 is minted on the destination chain; the reverse “burn-and-release” returns the locked USD₮. The goal is to unify USD₮ liquidity across networks without creating a separate or synthetic stablecoin.

Project documentation describes USDT0 as backed 1:1 by USD₮ that is held on-chain, with USDT0 serving as the omnichain representation used for inter-chain movement and usage. Some network partners also characterise USDT0 as convertible 1:1 with USD₮ across supported chains. Operational details on mint/burn, message validation and the specific contracts are covered in “How does USDT0 work (lock-and-mint / burn-and-release)?” and “Which networks are supported and what are the official contract addresses?”

USDT0 is used to move USD₮ across blockchains while keeping one unified supply. It enables native cross-chain transfers under LayerZero’s Omnichain Fungible Token (OFT) standard, so users and applications can hold and transact a USD-pegged balance on multiple networks without relying on third-party wrappers. This supports payments, transfers and portfolio moves between chains while preserving fungibility with USD₮.

For day-to-day users, USDT0 is used to bridge USD-denominated value between supported networks to access lower transaction costs or different dApps, and to consolidate or redeploy balances without selling out of USD₮. Official documentation lists cross-chain transfers and liquidity mobility as primary uses. Fee policies are defined by the project (e.g., no extra fee for native OFT transfers; a 3 bps fee for certain “legacy mesh” routes), with gas paid on the chains involved. See “What are the fees, limits and typical cross-chain transfer times?” for details.

For exchanges, market makers and protocols, USDT0 is used to standardise USD₮ movement across multiple networks, simplify listings on new chains and reduce fragmented pools. The OFT model is designed to maintain a single global supply across chains, which helps unify liquidity and simplifies accounting for integrations that support the standard. See “Which networks are supported and what are the official contract addresses?” for implementation guidance on contracts and networks.

Developers use USDT0 as a stable settlement asset inside omnichain workflows. Because OFT abstracts cross-chain messaging and decimal handling, applications can build transfers, payments and settlement that span chains while treating USDT0 as one token. Technical references and quickstarts describe the transfer flows and contract patterns used.
