It Was Supposed to Be $1 but It Hit Zero: A 99% Collapse

Balance, an algorithmic stablecoin, effectively hit zero after losing 99% of its value following the exploitation of a pricing vulnerability in its protocol.

As security vulnerabilities continue to plague the cryptocurrency world, Balance Coin was the latest target. This algorithmic stablecoin, which is normally expected to remain pegged to the $1 level, plummeted to as low as $0.0014 following an attack on Wednesday. Approximately $3.5 million in nominal market capitalization evaporated almost entirely within minutes.

According to blockchain data, the attacker seized approximately $912,000 worth of assets from Bitcoin vaults within 42DAO, the governance entity behind the project. According to the system’s operation, users minted this stablecoin by providing Bitcoin (BTC) as collateral. However, the attacker managed to input an erroneous Bitcoin price into the system by manipulating the mechanism known as an oracle, which provides price data from the external world.

Oracle Manipulation and Security Vulnerability

Security firm SlowMist stated that the attacker exploited a loophole in the system to show the Bitcoin price as abnormally low. The protocol’s lending contract accepted this faulty price without any verification or liquidation delay. This situation allowed the attacker to instantly seize numerous vaults that should not have been liquidated and swap the collateral inside for profit.

This incident once again highlights how critical security vulnerabilities are in the decentralized finance (DeFi) ecosystem. Especially on platforms involving complex code structures and technical processes, the smallest logic error can lead to millions of dollars in losses. With recent technological developments, including the integration of artificial intelligence systems, protecting digital assets has become more challenging than ever.
