Congratulations! Your MetaMask wallet is now configured to interact with the Optimism network. Next up, you need to fund your wallet.

Funding Your Optimism Wallet

Similar to Base, Optimism operates as a Layer 2 solution on the Ethereum Mainnet, utilizing Ether (ETH) as its primary currency. This means that transactions for gas are settled in ETH. To conduct transactions on Optimism, it's essential to first ensure that your wallet is funded with ETH.

Bridging ETH From Mainnet To Optimism

If you're using a MetaMask wallet, you can simply click on the 'Bridge' option located between Swap and Portfolio, or visit https://portfolio.metamask.io/bridge. From there, select Mainnet as the network you are bridging from and choose ETH as the currency you wish to bridge. Then, designate Optimism as the chain where you want to receive your bridged ETH. After confirming your selection, all that's left is to wait for the transaction to be processed. Congratulations, you've successfully bridged ETH from the Mainnet to Base and are now prepared for the Gloomers NFT mint.
