Important notes

ETH on Optimism is not ETH on Ethereum. Both are called ETH, but each network keeps its own balance, and ETH on Ethereum cannot pay a fee on Optimism. To move ETH between them, use Bridge.
The same address on every EVM network. Your Optimism address is also your address on Ethereum, BNB Chain and the other EVM networks. A token sent on another network arrives there, not on Optimism, so check the network before you send or withdraw. See I sent crypto on the wrong network.
Approvals last until you revoke them. Approve only what a DApp needs, and revoke what you no longer use. See Token approvals.

Questions

In the help center

Which network do I choose to withdraw to FxWallet from an exchange?

Optimism, which some exchanges call OP Mainnet. In FxWallet the network is called Optimism: tap Receive and choose ETH on Optimism to copy your address. It is the same address as on Ethereum, so make sure the exchange sends on Optimism. See Deposit or receive crypto.

Can I send tokens on Optimism without ETH?

Yes. Pay the network fee with a Gas Card. It uses Normal speed and does not work with hardware wallets. See Gas fees and Gas Card.

Does OP pay the fees on Optimism?

No. Fees on Optimism are paid in ETH. OP is the network’s governance token, an ERC-20 token that you hold and send like any other.
