Actual behaviour

It indicates an Eth balance change on the wallet, which shouldn't exist:

            "balance": {
                "*": {
                    "from": "0xdb41af42d950ca",
                    "to": "0x12294729269af74f8"

Steps to reproduce the behaviour

As you can see, the wallet Eth balance from the calling wallet 0x22810... went from 0xdb41af42d950ca to 0x12294729269af74f8 (from 0.061 to 20.94 ETH)

The decoded transaction data is just an approve method, so we wouldn't expect any balance change when using trace_call.

      "hex": "0x02540be400"
    }
  ],
