# Asset Guide - USDT

## **What is USDT?**

USDT0 is the official USDT token on Sei, fully backed 1:1 by Ethereum's native USDT and bridged via LayerZero’s OFT (Omnichain Fungible Token) standard. It enables secure, scalable, and omnichain-compatible transfers while serving as the default stablecoin for lending, swapping, and incentives across the Sei DeFi ecosystem.

### **Where do I get USDT?**

You can get USDT from:

* **On-chain swaps** via Sei-based DEXs like [Symphony](https://symph.ag/).
* **Centralized exchanges** (CEXs) → Acquire USDT and bridge it to Sei.
* **Bridging** from Ethereum and other chains using [Yei bridge](https://app.yei.finance/bridge/) or LayerZero-enabled bridges like [Legacy Mesh](https://usdt0.to/transfer).
