- [ ] Deployed contract's verified code (and all dependencies) match the code in master
- [ ] Contract constructors have correct arguments
- [ ] The transactions that interacted with the newly deployed contract match the deploy script.
- [ ] Governance proposal matches the deploy script
- [ ] Smoke tests pass after fork test execution of the governance proposal
