In the review I will focus on the bridge page because it will be mostly visited. If we are talking about mass adoption in crypto, some suggestion would be oriented on a regular users (the ones that just got how to use metamask and asks us how to transfer the tokens across the chains)
1 . When user adds the tokens he wants to bridge without connecting the wallet and is unable to enter the amount of tokens - its not obvious for a regular user what to do further
Solution
When user clicks on amount form - exclaim the connect wallet button (red border or an animation on the button)
Example
Solution
Separate the destination and Gwei info. Example: Put gwei number and icon below the token icon
Solution Add the approximate transaction cost above the action button.
Example My favourite solana bridge swim solved the problem like that
