Yes. You can connect your wallet to the Ropsten network to test an ERC-20 token generation on Ethereum (ETH), connect to the BNB Testnet if you want to test token generation on the BNB Chain (Binance Smart Chain), or connect to the Mumbai Testnet if you want to mint tokens on the Polygon (MATIC) Testnet.
Make sure your wallet is connected to the correct corresponding network. For example, if you minted on the ETH chain, you need to set your wallet to the Ethereum Mainnet to view your minted tokens on the 'My Mints' page.
