btw, had a quick look and don't think this is going on the right track.. we're changing a lot of things unrelated with private keys... hard coding RPCS for instance, is one.. but there are others...
have you ever looked at file src/test/utils/addresses.ts ? we have everything there needed for refactoring the tests around private keys.

Ok thank you Paulo, but the purpose was to no expose private keys in the code, now we place them in a separate file... it is a bit confusing, I remeber Alex said to not share private keys anywhere, we can have them as env vars, but it is not clear the scope of the issue then.
