Description

  • Track transaction statuses on per signature basis to identify which signature for a transaction was included to detect re-orgs specifically for it
  • Update the confirmation logic to identify regression in a signature’s transaction status when no or processed status is received to detect re-orgs
    • A transaction can revert back to no status or processed from confirmed status
    • A transaction can revert back to no status from processed status
  • If a re-org is detected, restart the retry/bump loop for it to try to get the transaction re-included

this is out of scope of the reorg, but pushing it here so we don't need to make a separate merge: https://smartcontract-it.atlassian.net/browse/NONEVM-1015
