A list of 10 accounts that were at risk was released by the team; these accounts would have been at risk between midday September 11th and early morning of September 12th; no action is required for addresses that are not on this list; for those that are listed the announcement directs users to https://authorizations.airswap.io/ where they can revoke authorizations for the contract Link
