[MartinGbz]

General Changes

Based on a request from Optimism team, here's a PR that updates the optimism icons.

Context: https://docs.google.com/document/d/11c8dMHw7u3vmoWhPCj8PTG1AmHFwH1GdxbHzGYrfxcY/edit#heading=h.tr02im5k88nh

fyi, some update made by myself:

• a white background has been added to the OP Mainnet logo (otherwise the white in the icon was transparent)
• the OP token has been resized to the same size than other icons

📦 Next.js Bundle Analysis for aave-ui

This analysis was generated by the Next.js Bundle Analysis action. 🤖

🎉 Global Bundle Size Decreased

Page	Size (compressed)
global	544.59 KB (🟢 -145 B)

Details

The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

If you want further insight into what is behind the changes, give @next/bundle-analyzer a try!

One Page Changed Size

The following page changed size from the code in this PR compared to its base branch:

Page	Size (compressed)	First Load
/bridge	35.88 KB (🟢 -25 B)	580.47 KB

Details

Only the gzipped size is provided here based on an expert tip.

First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 20% or more, there will be a red status indicator applied, indicating that special attention should be given to this.
