hi @0xonerb

can you show me what are you approving ?

In this case it's a regular ERC-20 Approve call.

On metamask it shows the amount correctly, but when testing wallet with authentication we are seeing "unlimited".

Hey @rtomas... as @0x33dm said, it's a regular ERC-20 Approve call.

Hey @rtomas, here are two transactions:

• Transaction using AppKit: https://optimistic.etherscan.io/tx/0x177cd5aa50ec82e59c774ebb2694ca77ded0f82530d25d5777b3e9f6f7699e61

As you can see, in our app we made a transaction with an amount of 5:

The AppKit modal shows Unlimited WETH??

• Transaction using MetaMask: https://optimistic.etherscan.io/tx/0x1d37ed2aadaae405bf1ddf7cdc7fd52571231d1e5fb06677903722c832b46558
