USDT is not limited to a single blockchain. It operates across multiple networks including:
- Ethereum - as an ERC-20 token

This multi-chain presence provides flexibility and accessibility for users across different blockchain ecosystems.
Use Cases
USDT serves several important functions in cryptocurrency markets. Traders use it to quickly move value between exchanges without converting to fiat currency. It provides stability during volatile market conditions and enables international transfers with minimal fees compared to traditional banking.
Regulatory Considerations
Tether Limited has faced regulatory scrutiny regarding reserve backing and transparency. Multiple investigations and audits have been conducted to verify that USDT tokens are properly collateralized. Users should be aware of ongoing regulatory discussions surrounding stablecoins globally.
