use metamask and then connect it to the bridge (linked above) to swap. if you use trust wallet, you can also swap them directly (but only for bnb though, so you need to convert your usdt to bnb first, not really efficient).Does metamask support BSc network?
Yes; MetaMask can be used with all EVM-compatible networks, BSC included. You can use your wallet to access the majority of dapps on BSC. To do so, make sure you have added the BSC network to your wallet (see below), and that you've selected it. How do I add BSC to MetaMask? See here for a how-to covering adding the network.
