Improve loading time when set max amount for ETH for Bridge with Superhero-wallet

[Andreea167]

Steps to reproduce:

1. Navigate to DeFi -> Bridge (on dev env)
2. click connect an Ethereum wallet
3. connect an Ethereum wallet via Superhero-Wallet
4. Click "Max"
5. Notice that it takes like 10-15 seconds until the max amount is displayed into the input text. -> which is quite a long amount of time

Notice that if you connect a MetaMask-Ethereum wallet and make the same steps it takes like 1-2 seconds which is the expected result
