🚨 From the dollar to zero in a blink of an eye
A "ghost price" of Bitcoin destroys the Balance stablecoin in a single transaction
The algorithmic stablecoin
#BalanceCoin (
#BLC ) suffered a catastrophic collapse after falling victim to extreme manipulation of its price oracle.
In a single transaction, an attacker injected a
#bitcoin fictitious and unrealistically low price into the lending protocol, triggering the immediate liquidation of completely healthy vaults and draining about $912,000 in reserves. As a result, the token lost 99.9% of its value within minutes.
Attack Anatomy: Step by Step
According to security signature analyses such as SlowMist and PeckShield, the exploit was carried out through a direct flaw in the smart contract logic:
Step 1: Oracle Manipulation (Fake the price feed)
The attacker managed to alter the external data source (oracle) and injected a price of
#BTC absurdly low into the lending system. The contract accepted the data immediately because it lacked range limits (sanity checks) to validate whether the price was consistent with the real market.
Step 2: False Insolvency of the Vaults (Vaults look unsafe)
Assuming that Bitcoin had crashed, the protocol instantly marked vaults as "undercollateralized" even though they were actually fully backed and secure.
Step 3: Instant Liquidation and Extraction (Seize and swap)
Without any safety wait period or delay (liquidation delay), the attacker liquidated the vaults eligible by mistake, confiscated the collateral in BTC, swapped it for profits, and left a financial hole that destroyed the stablecoin’s peg.
