Tether’s USDT is the most widely adopted stablecoin in the world. It’s a fiat-backed digital dollar that powers a growing universe of exchanges, wallets, payment apps, and DeFi protocols across more than a dozen chains. For many people, USDT is the stablecoin.

But USDT is not inherently multichain. Every blockchain has its own version of USDT, and in addition to native USDT there is now a growing tangle of wrapped, bridged and synthetic variants. These different versions aren’t interoperable and have introduced new layers of risk, friction, and liquidity fragmentation to an asset that was designed to be stable and secure.

USDT0 was designed to solve this. But what exactly is USDT0, and how is it different from USDT? Let’s break it down.

USDT0 the omnichain deployment of USDT, built to unify USDT liquidity across blockchains using LayerZero’s OFT (Omnichain Fungible Token) standard. It’s the same USDT, backed 1:1 by USDT held on Ethereum but made natively composable across chains.

In other words, USDT0 is not a wrapped asset, a synthetic representation, nor a fork. It’s an omnichain liquidity standard for USDT.

Stablecoins are involved in over two thirds of all onchain transactions, and are increasingly being embraced by institutions and policymakers as the world moves onchain. Within this backdrop, USDT remains the largest and most widely distributed stablecoin, and USDT0 builds on this foundation by extending its utility and reach via a unified, omnichain liquidity layer.

USDT0’s omnichain liquidity layer unlocks:

• Unrivaled Capital Efficiency: USDT0 makes stablecoin liquidity more unified and accessible across chains. Users and protocols can access deep, reliable liquidity on any supported network as capital moves natively to wherever it’s needed most.

• Composability Without Compromise: Because USDT0 uses the OFT standard, it can be natively utilized across all supported networks. This means USDT0 behaves exactly the same on Arbitrum, Optimism and beyond, with full composability across the stack.

• Simplicity and Trust: USDT0 reduces the complexity and risk of multichain stablecoin activity. All USDT0 transfers are transparent, fast and fully backed, with immutable messaging endpoints and dual-layer DVN verification ensuring transaction integrity.

• Forward Momentum with Backwards Compatibility: USDT0 is live on Arbitrum, Optimism, Ink, Unichain, SEI, Berachain, and Corn—with more integrations coming soon. At the same time, popular networks that don’t support the OFT standard or native USDT0 minting yet can still leverage USDT0’s unified liquidity layer via the Legacy Mesh.

USDT ushered a new era of global, permissionless finance, where anyone can access a stable, digital dollar from anywhere in the world. USDT0 builds on this legacy and takes it to the next level. By unifying USDT liquidity across chains, USDT0 removes the friction and fragmentation that have kept onchain finance from reaching its full potential. What once required multiple contracts, bridges and workarounds now works natively and securely out of the box.

So if you’re holding USDT today, well done—you’re already using the most trusted stablecoin in the world. But if you want to move your USDT seamlessly across chains and seize new opportunities, then USDT0 is the answer.
