I'm sorry for my newbie question since i'm still new here as well as crypto world.... what is ETH bridge that we're finalizing? what's it for? and will it bring more benefits to us? if yes, how?

It means assets can move from the Ethereum ecosystem to Elrond and back with ease (there's a bridge at the moment but slow and limited) This will mean a lot more adoption on the network, so tokens, NFTs, those that chase defi Apr. It makes it a lot easier for projects to migrate too, thus increasing the ecosystem. So it's a vital component

Eth bridge will connetct elrond blockchain to ethereum. This will allow for tokens on the eth blockchain to come to elrond
