We’re excited to announce support for USDT0, the omnichain version of USDT, now fully integrated into LI.FI’s routing via Glacis.

Built using LayerZero’s OFT (Omnichain Fungible Token) standard, USDT0 allows users to move USDT across chains without changing the asset itself.

USDT0 is available across all supported chains through LI.FI’s API, SDK, and Widget.

Why is USDT0 different?

USDT has historically been deployed as separate contracts on different chains, for example, USDT on Ethereum and USDT.e on Avalanche. These independent deployments often result in fragmented liquidity across networks.

With USDT0, USDT introduces a single omnichain token that:

• Is always 1:1 backed by canonical USDT on Ethereum

• Can be burned and minted across chains using LayerZero messaging

• Avoids liquidity pool reliance, reducing cost and price impact

Move USDT0 from Ethereum to Berachain, Arbitrum, and more — powered by LI.FI & Glacis.

What this unlocks

USDT0 simplifies USDT across chains. LI.FI brings it out of the box:

• No additional integration: Apps don’t have to implement USDT0 logic. It’s already comes out of the box via LI.FI.

• No versioning or token handling: Apps don’t need to handle multiple USDT variants across chains.

• Minimal slippage: Transactions use burn-and-mint, not pools — the amount sent is the amount received.

• No updates: New routes unlock automatically as LI.FI and USDT0 go live on more chains.

What is USDT0?

USDT0 is a version of USDT built using LayerZero’s Omnichain Fungible Token (OFT) standard. It allows USDT to move across supported chains through burn-and-mint messaging, without relying on wrapped tokens or liquidity pools. The result is the same USDT, available more efficiently across chains.

What is Glacis?

Glacis is building an infrastructure platform to unify and secure Web3 for an easier user experience. AirLift, a universal token interface, was built in close collaboration with LI.FI to address poor UX. Glacis’ AirLift removes this overhead for anyone using LI.FI. Any token, any size, anywhere.

What is LI.FI?

LI.FI is an onchain liquidity API to swap, bridge, and zap across all major chains. It provides the most comprehensive price comparison and trade execution across 40+ chains, spanning multiple virtual machines (EVM, SVM, altVMs) and has been integrated by over 400 customers, many of them enterprise companies. It offers the broadest chain and asset coverage, high reliability, and built-in redundancy by pulling from multiple liquidity sources on every chain.
