Describe the bug

I'm triggering the Send Malicious from the test dapp, and I'm seeing as if I would get a greater USDC value (native token) in return :thinking_face: This could trick users to perform tx's where they think they get more money back. It's seems an issue with Arc network solely

Expected behavior

Estimated balance value should be correct
