startPrank support is coming. It is implemented in hevm, but we haven't upgraded yet.

Are you sure you are calling startPrank? The trace shows startPrankXD.

@arcz yes sir I did call startPrank(),as i saw the same trace message.Cross checked on my part have been fuzzing using echidna and its been an issue converting foundry tests into echidna ones

[ggrieco-tob]

Can you try using echidna from master?
