contracts: Fix Medium OZ audit findings #452

Closed maurelian closed 2 years ago

maurelian commented 2 years ago

This PR fixes the Medium severity issues issues in the OpenZeppelin audit (which is not yet public). Each commit in this PR clearly references the finding that it addresses.

In order to review, I suggest comparing between the audit report (see the Open Zeppelin Audit Resolution doc in Notion), and the commit which mentions it.

This PR builds on #455, but is split out to keep the review manageable.
