Implement bep3 evm native conversion logic #1848

Really good test cases covering dust, too small of balance, and insuffient balances on both the sdk and erc20 sides.
Let's just add some defensive testing to ensure all four bep3 assets are covered. In addition to using a map for denom lookup, removing unused code, and making extracted helpers private (or adding unit tests for them).
Looks great otherwise. Refactoring implementation is optional -- just added my thoughts there on readability & complexity.

Nice, normally I'd say use a map[string]struct{}, but with 4 items the benefited clarify and simpler logic in isBep3Asset is nice 👍

This actually makes the tests quite a bit easier to read -- easy to see that all denoms are tested and much more resistant to refactorings that could drop a denom, accidentally rename one, break the check some other unique way, etc

I see what you mean now, and this is a nice approach showing there is are two paths in the logic: One for bep3 assets, and one for not. Also, makes it clear that the amounts are only modified in the bep3 case, but also keeps the dirty details down a level in a function call.
