From 5329aa3786ee654d093ef7ed46cad9d1b3e948c9 Mon Sep 17 00:00:00 2001 From: Nicolas Gotchac Date: Mon, 31 Oct 2022 04:50:21 -0400 Subject: [PATCH] Fix trace call for inner reverts (#25971) Inner call reverts will now return the reason similar to the top-level call. Separately, if top-level call is of type CREATE and it fails, its `to` field will now be cleared to `0x00...00` instead of being set to the created address. ---
