On July 22, 2026, Balance Coin’s value plummeted from roughly $1 to just $0.0014, losing more than 99 percent of its price within hours. This crash wiped out about $3.5 million in market value and was triggered by a sophisticated attack targeting the Bitcoin price oracle that Balance relied on.
Oracle Manipulation Sparks Liquidation Cascade
Balance Coin’s design depended heavily on a Bitcoin price feed to maintain its peg and safeguard vaults backed by BTC collateral. The attacker exploited this single price feed by artificially lowering the reported BTC price. This manipulation made otherwise healthy vaults appear undercollateralized, prompting the protocol to liquidate them incorrectly.
Those forced liquidations unlocked the ability to mint new BLC tokens, which were immediately dumped into the market. Selling freshly minted tokens into already panicking liquidity pools caused a sharp price decline, fueling a destructive feedback loop. Even a modest price shift in a thinly traded market was enough to trigger this collapse.
Profiting from the Breakdown
Security firms like SlowMist and PeckShield traced the exploit back to a single attacker who netted approximately $912,000 by minting and offloading BLC tokens on PancakeSwap. The attacker converted these into USDT and BTCB, capitalizing on the market chaos. Meanwhile, 18,100 token holders faced near-total losses as the circulating supply of around 3.5 million BLC became essentially worthless.
This event shows the critical risk of relying on a single price oracle, especially for stablecoins backed by volatile assets like Bitcoin. It also highlights how improper liquidation mechanisms can amplify damage. Attackers only needed to nudge the BTC price down briefly to drain millions in collateral and confidence.
