Failed Swaps Following USN Contract Maintenance

Today, following a USN maintenance, we have identified 20 swap transactions that have failed.

Those transactions resulted in a Exchange_callback_post_withdraw call followed by a Ft_resolve_transfer call.

For every failed swap, the Ft_resolve_transfer call transferred the USN to the Ref Exchange contract (v2.ref-finance.near), USN that are now in posession of the Ref DAO (ref-finance.sputnik-dao.near).

The accounts that have been identified for a total of 1,233.402704 USN.

Credits to Francois and Bertrand from Pikespeak for their help to quickly identified the impacted addresses.

Once @Marco has doubled confirmed the above, the DAO will proceed to the USN transfers back to the identified accounts.

Not all failed swap actions would cause a lostfound process. Only those swappers who have no inner account in ref-exchange, would find their usn token-out in lostfound. Like usn-unofficial.poolowner.near in previous table, he has inner account, all usn he swapped out now lies in his inner account.
