42DAO Exploit Drains $915,000 from Balance Protocol, BLC Token Collapses

The Balance Protocol, a decentralized stablecoin ecosystem governed by 42DAO on the BNB Chain, was hit by an exploit on Tuesday that resulted in the loss of approximately $915,000. Following the incident, the protocol’s native stablecoin, Balance Coin (BLC), experienced a near-total collapse, losing over 99% of its value.

According to security reports tracked by KuCoin and secondary security sources, the attacker targeted the protocol’s BTCB vaults. The exploit reportedly involved the manipulation of an oracle or the exploitation of an abnormally low BTCB price reading, which allowed the attacker to trigger liquidations within the vault system at manipulated rates.

Mechanism of the Collapse

Balance Protocol operates as an algorithmic stablecoin system where users mint BLC by collateralizing assets such as BTC, ETH, and BCH. The protocol is intended to maintain a $1 peg through an algorithmic supply adjustment mechanism managed via 42DAO.

The exploit disrupted this mechanism by targeting the collateral valuation. Reports indicate that the attacker leveraged the price discrepancy to drain liquidity, subsequently swapping the stolen funds for USDC and BTCB through the decentralized exchange PancakeSwap. This sudden drain and the subsequent liquidation of vaults caused BLC to crash from its $1 target to approximately $0.0013 within a few hours.

Current Status and Impact

Data from market trackers shows that the BLC token remains down roughly 99.8% over the last 24 hours. The high volume of trading activity recorded during the event reflected widespread panic selling as the stablecoin de-pegged entirely from the U.S. dollar.

• Project Status: The 42DAO team has not yet released an official post-mortem or a formal recovery plan in the available public sources.
• User Risk: Liquidity providers and vault owners appear to be the most affected, as many positions were forcibly closed at the manipulated price levels.
• Asset Safety: The stolen funds moved through BNB Chain decentralized protocols, and recovery remains unlikely without centralized intervention or the freezing of funds on secondary platforms.

The incident highlights persistent vulnerabilities in algorithmic stablecoin price oracles, specifically those tied to liquidation triggers. While other major stablecoins on the BNB Chain, such as USDT and USDC, maintained their pegs during the event, BLC holders face significant losses as the protocol’s core stability mechanism remains compromised.
