If you want to move your Ethereum from your Trust Wallet to Coinbase, you’ll need to export your Trust Wallet private key. You can do this by going into your Settings, selecting Private Keys, and then selecting Export Keys.
Make sure to write down your private key somewhere safe, as you’ll need it in the next step.
Once you have your private key, open up Coinbase and select the Accounts tab. From there, select the Send button for Ethereum. In the “To” field, paste in your Ethereum address that you got from Trust Wallet.
In the “Amount” field, enter how much Ethereum you want to send. Finally, click Send Funds.
That’s all there is to it! Your Ethereum should now show up in your Coinbase account.
