I have searched if there are any threads here about Rabby Wallet and it seems there are none. I was using a metamask for my daily use. But for me, the meta mask works too slowly. Recently, I found out about Rabby wallet which works exactly like a meta mask but faster, and it has some extra features as well.
The Rabby wallet shows your balance across all the blockchains, which is not possible in metamask. Moreover, if you lock your balance on a website, it will be deducted from your wallet, and if you forget the website's URL, you cannot find where you staked your balance. However, the Rabby wallet has a unique feature. It will show where you have staked/locked your money. Check the screenshots below.
For example, these 700 dollars are not in a single chain but in all chains.

This is where I staked/locked my ETH
