The company has said it will not redeem any of those tokens and is trying to recover them to prevent them from entering the broader ecosystem.

"If you receive any USDT tokens from the above address, or from any downstream address that receives these tokens, do not accept them, as they have been flagged and will not be redeemable by Tether for USD," said the announcement.

Tether said its issuances have not been affected by the attack and its tokens remained fully backed by assets in reserve accounts.
