Transferring Wrapped Ethereum out of Coinbase Wallet

Hi guys,

I have some WETH (wrapped ETH) in my Coinbase Wallet. The WETH is on the Polygon blockchain. I want to sell the WETH and was hoping someone could provide guidance on how I can do this?

It doesn’t seem possible to convert the WETH to ETH using Coinbase Wallet and I can’t transfer the WETH to my Coinbase account as there is no option to deposit WETH to Coinbase. I also can’t convert the WETH to any other coin such as USDT and then transfer the USDT to Coinbase - Coinbase Wallet says I needs for example $0.07 MATIC to proceed. I have some MATIC in my Coinbase account but the MATIC is on the Ethereum blockchain.

Is there any way I can transfer the MATIC I have in my Coinbase account, which is on the Ethereum blockchain, to the Polygon blockchain to pay fees to convert the WETH to USDT? Or alternatively is there any other way that I can get the WETH out of Coinbase Wallet and sell it?

Any advice would be much appreciated ????
