Exhibit 1-
Remove Orchestrator address initialization in the policy.
Exhibit 2-
Reorder Transaction struct elements to pack values and save storage.
Exhibit 3-
No action. I'm ok with leaving the index in the
TransactionFailedevent, since risk is minimal and it aids potential debugging.Exhibit 4-
No action needed.
Exhibit 5-
Removed unnecessary
deletecall.Exhibit 6-
Removed
transferValueWeiparameter in external_call.Exhibit 7-
Remove
dataLengthparameter in external_call. Load directly from array's storage.Exhibit 8-
No action. It doesn't save gas, and I think it's more legible as is.

Renamed
transactionsLengthtotransactionsSizeto follow market-oracle repo's convention.Exhibit 10-
No action needed, since we mitigated Exhibit 2.
