# 2.3 Acquiring Trading Tokens: aSEED on Mainnet and mUSDT on Testnet

### Trading on Acala Mainnet

On the Acala Mainnet, we use aSEED for buying and selling options. Additionally, it's essential to have some $ACA in your account to cover gas fees.\
\
You could get aSEED in [Acala Swap](https://apps.acala.network/swap).<br>

### Trading on Mandala Testnet

On the Mandala Testnet, however, you can obtain test tokens for trading interactions.

\
mUSDT is a test token used for mSEED options trading on the Mandala Testnet. Always make sure you have enough mACA (acquired through the [faucet](https://evmdocs.acala.network/tooling/faucet)) in your account to cover transaction fees. To get mUSDT, click the "Faucet" button and confirm the transaction. Once done, 10,000 mUSDT will be added to your balance. This can be done multiple times to accumulate more test tokens for trading.
