[evm] What about having 2 DenomUnits for UX?

Summary

Code4rena:

What about having 2 DenomUnits:

1. The smallest possible unit with Exponent = 0, universally called wei (i.e. Denom = "wei") for all such erc20 funtokens
2. The regular unit which uses the erc20 token's decimals, i.e. { Denom: bankDenom, Exponent: info.Decimals }

This first wei unit will be used as the coin's Base and the second unit as Display.

Yeah, I think that would improve the UX. That would bring about parity between MetaMask and Keplr/Leap.

The 0 exponent one's required and technically correct, but putting a second denom unit like you've described would make the behavior similar to NIBI's bank metadata:

    {
      "description": "The native staking token of the Nibiru network.",
      "denom_units": [
        {
          "denom": "unibi",
          "exponent": 0,
          "aliases": [
            "micronibi"
          ]
        },
        {
          "denom": "NIBI",
          "exponent": 6,
          "aliases": []
        }
      ],
      "base": "unibi",
      "display": "NIBI",
      "name": "NIBI",
      "symbol": "NIBI",
      "uri": "",
      "uri_hash": ""
    }

Integrating a change shortly.
