Hi,
I’m not familiar with FTX, but maybe it support connecting to Trezor? I don’t know. However, this is what you should try:
- Set up an account in a third party exchange which support connecting your Trezor, like Metamask.
- Add a new Trezor connected wallet in Metamask.
- Now you should see your BNB from your Trezor in your new wallet on Metamask.
- Transfer the BNB out of Trezor to another wallet (for instance on Binance).
- Transfer it back to Trezor, but this time be sure to use the Ethereum network for transfer.
About #1 to 4, see from this post. Be sure to substitute the Tx address in that thread with your own transaction address (but don’t show it to the public, please).
About #5, see this post first, about how to add an ERC20 token to Trezor Suite. After that, you can perform #5 above. See here for how to send ERC20 tokens to your Trezor.
So the whole processs is about - find and see your BNB, transfer them out to a wallet that support BNBs, then transfer them back to Trezor correctly.
