# Using a CEX

## **Buying MATIC/USDT on a CEX**&#x20;

Buy MATIC/USDT on a CEX (Centralized Exchange) such as Binance, Coinbase, KuCoin, etc. \
Please check on your chosen CEX if they support Polygon withdraws. \
\
CEXs differ in what chains they support and some do not support certain chains, or withdrawals, depending on the asset.

1. Buy MATIC/USDT on your preferred CEX.
2. Withdraw MATIC/UDST to your Metamask address. **Make sure you select the polygon chain**
