Stablecoin protocol Helio, which issues the U.S. dollar-pegged HAY stablecoin, said in a Dec. 7 tweet that it has bought back $3 million worth of bad debt in HAY thus far in the open market. The day prior, blockchain infrastructure platform Ankr stated it would allocate $15 million to buy back the bad debt resulting from its recent exploit and the resultant overcirculation of HAY.
A series of seemingly unrelated incidents occurred on Dec. 2 when a hacker manipulated vulnerabilities in Ankr’s smart contract code and compromised private keys after a technical upgrade. As a result, the hacker minted 20 trillion Ankr Reward Bearing Staked BNB (aBNBc), which was pegged to BNB (BNB), and dumped them, with the price of aBNBc plunging to less than $2 from around $300.
