When using Optimism, transaction fees must still be paid in Ether. As a result, for the first transaction, when your asset will enter layer two from the Ethereum network, you still have to pay the high Ethereum network fee. But once your property enters tier two, the fees will be significantly reduced.

Always be strong! :) If you can't take it off! ️

The text explains that while initial transactions on Optimism require high Ethereum network fees, subsequent transactions on layer two have significantly reduced fees. 🎭
