{"investigation":{"slug":"balance-coin-blc-42dao","entity_name":"Balance Coin (BLC) / 42DAO","trust_score":4,"severity_base":null,"score_modifier":0,"confidence":0.7,"status":"draft","content_type":"investigation","summary":"Balance Coin (BLC), a dollar-pegged algorithmic stablecoin issued by the BNB Chain protocol 42DAO, collapsed by approximately 99% on July 22, 2026 after an attacker manipulated the protocol's price oracle to trigger fraudulent liquidations and mint millions of unbacked BLC tokens. Blockchain security firms SlowMist and PeckShield estimated the direct loss at roughly $912,000–$915,000, with BLC's market value falling from near its $1.00 peg to fractions of a cent. Multiple crypto-news outlets reported the incident consistently, though 42DAO itself does not appear to have issued a public statement or recovery plan at the time of reporting.","sections":[{"content":"On July 22, 2026, Balance Coin (BLC), an algorithmic dollar-pegged stablecoin minted by depositing BTC, ETH, and BCH collateral into the 42DAO protocol (a MakerDAO-style vault system on BNB Chain), lost its peg and collapsed by over 99% within hours. According to analysis attributed to blockchain security firms SlowMist and PeckShield, an attacker used 42DAO's Median Oracle mechanism to inject an artificially low BTCB (Binance-pegged Bitcoin) price into the protocol's accounting contract via the Spotter contract's 'poke' function. Because the Spotter component allegedly lacked price deviation checks, maximum drawdown limits, and a minimum price floor, and because the protocol's 'Dog' liquidation module accepted the falsified price without a time delay or secondary validation, the manipulated price made healthy, overcollateralized BTCB vaults appear insolvent. The attacker then triggered liquidations across multiple vaults in a single transaction, seizing collateral at the fraudulent price and profiting from the gap between the manipulated and real market valuation of BTCB.","heading":"The Oracle Manipulation Exploit","sources":[{"url":"https://cryptorank.io/news/feed/162be-42dao-oracle-exploit-crashes-balance-coin-blc-99-after-912k-defi-hack","name":"42DAO Oracle Exploit Crashes Balance Coin (BLC) 99% After $912K DeFi Hack — CryptoRank","type":"news_article","credibility":2},{"url":"https://www.cryptotimes.io/2026/07/22/42daos-blc-stablecoin-depegs-to-near-zero-after-912k-oracle-exploit/","name":"42DAO's BLC Stablecoin Depegs to Near Zero After $912K Oracle Exploit — CryptoTimes","type":"news_article","credibility":2},{"url":"https://www.cryptopolitan.com/balance-coin-crashes-after-oracle-attack/","name":"Balance Coin crashes 99% after oracle attack drains $912,000 from 42DAO — Cryptopolitan","type":"news_article","credibility":2}],"severity":"critical"},{"content":"Reporting indicates the attacker exploited a compromised GemJoin contract to mint approximately 4.5 million BLC tokens from a null address — several times the protocol's reported pre-attack circulating supply of roughly 3.5 million BLC — and transferred them to a PancakeSwap V2 liquidity pool, swapping the newly created tokens for Binance-pegged USD (BSC-USD) and BTCB. A second, smaller transaction using the same technique reportedly minted an additional 5,900 BLC approximately two hours later and drained further assets from liquidity reserves. The resulting flood of unbacked supply overwhelmed BLC's liquidity pools, driving the token's price down from approximately $1.00 to figures reported between $0.0008 and $0.0025 depending on the source and timestamp — a decline of roughly 99–99.9% within 24 hours.

Reporting states the exploit did not require a sophisticated code break, but instead relied on the absence of basic safeguards around oracle price validation and liquidation triggers. The incident was described in coverage as part of a pattern of recent oracle-related DeFi exploits, with comparisons drawn to Allbridge (~$1.65M) and Echo Protocol, and reporting noted it was the third major BNB Chain DeFi exploit within a two-month span, following incidents affecting DxScale (~$7.3M) and TesseraDAO (~$2.5M).","heading":"Protocol Design Failures","sources":[{"url":"https://www.cryptotimes.io/2026/07/22/42daos-blc-stablecoin-depegs-to-near-zero-after-912k-oracle-exploit/","name":"42DAO's BLC Stablecoin Depegs to Near Zero After $912K Oracle Exploit — CryptoTimes","type":"news_article","credibility":2},{"url":"https://www.techtimes.com/articles/321253/20260722/stablecoin-blc-loses-dollar-peg-after-oracle-attack-drains-915k-42dao-protocol.htm","name":"Stablecoin BLC Loses Dollar Peg After Oracle Attack Drains $915K From 42DAO Protocol — Tech Times","type":"news_article","credibility":2}],"severity":"high"},{"content":"As of the most recent reporting reviewed, 42DAO had not issued a public statement, post-mortem, or recovery plan addressing the exploit.
