Show Token Approval Amount on Confirmation Screen

[vnaysngh]

Description

Currently, when users approve a token for trading, USDT in this case, the approval amount is not displayed on the confirmation screen. This can lead to confusion, as the default approval amount in MetaMask is often unlimited. If users want to set a custom approval amount, they need to manually check the token amount from the main screen before entering it in the MetaMask popup.

Steps to Reproduce

1. Connect the wallet to Sepolia.
2. Initiate a token trade that requires approval.
3. Proceed to the approval step.
4. Notice that the approval amount is not displayed on the confirmation screen.
5. In the MetaMask popup, the default approval is unlimited, and users have to manually reference the trade screen for a custom amount.

Expected Behavior (can choose between 1 and 2)

1. The approval amount displayed in the MetaMask popup should match the amount entered on the swap screen.
2. The approval screen should display the exact amount being approved so users can easily reference it when setting a custom amount in MetaMask.

Additional Context
• Adding this information improves transparency and reduces the risk of unintentionally approving an unlimited amount.
• Users should not have to navigate back and forth to confirm the correct token amount for approval.

Hey @vnaysngh , your proposal is great!

But for now, we are sending unlimited amount to approve a token, so there is no point in showing it on the Confirm screen.

As for partial approvals, this feature is included into the roadmap and will be implemented in the near future.

Thanks.
