Now you need to purchase some BNB to swap for your $TUPAC. You can do this directly in Trust Wallet by clicking buy, or on another market such as Binance, Kraken or Coinspot, and then transfer into the wallet you created in Step 1.
If you are using Trust Wallet, you will need to swap this BNB to the smart chain by clicking More and then selecting Swap to Smart Chain. In MetaMask this is automatically done for you.
