According to Blockaid, an attacker used a flash loan to mint inflated tranche shares on Tranche Vault, then redeemed the vault's remaining USDC. Roughly $1.01 million has been drained so far across about two transactions, and the exploit is described as ongoing. Blockaid shared the exploiter addresses, an example exploit transaction, and the victim vault link. Separately, the post congratulates 0xPredicate on its Series A and notes Blockaid's partnership with the team on transaction-level compliance for regulated onchain markets.
