What happened
After the attack on Ankr’s aBNBc token, an address exchanged 10 BNB for 15.5 million BUSD with the help of the Ankr vulnerability, resulting in the emptying of the Hay liquidity pool. Another user made a profit through the same method, with an income of about $3.5 million. Helio Protocol tweeted that the BNB pledged by users is safe, and the official is in close communication with the Ankr team to discuss the restart plan of aBNBc.
