Balance Coin fell 99.9% after the protocol hack

Balance Coin plunged 99.9% after reports of a hack of Balance Protocol, with losses from the incident estimated at $912 000 to $915 000. This hit traders holding BLC and DeFi users on BNB Chain, where the token was supposed to stay near $1.

According to a market aggregator, the algorithmic stablecoin BLC lost its peg to USD and collapsed almost to zero after the attacker, according to the incident version, exploited a vulnerability in the protocol’s pricing mechanism. Specialists were the first to report a possible hack, and a short report was later published by another analytics company. At the time of writing, the aggregator showed a price of about $0,000965, a 24-hour volume of $103 023, and a #4145 ranking. For readers following similar failures, this is another example of how quickly a technical flaw turns into a market crash.

What exactly went wrong in Balance Protocol?

Balance Protocol runs on BNB Chain and is built on logic similar to MakerDAO. Users deposit BTCB as collateral and receive Balance Coin in return, which is supposed to stay near $1. When collateral falls below the threshold, the position is automatically liquidated. It sounds simple. But the whole system depends on the price recorded by the oracle.

That is where the problem arose. The report noted that the architecture has two modules, Spotter and Dog, but no OSM, meaning Oracle Security Module. In MakerDAO, this is what filters out sharp spikes and adds a delay before a price update. Balance did not have this barrier, so the attacker was able to manipulate the BTCB price in the Median Oracle and force Spotter to record an abnormally low value without additional checks. Dog then worked with the fake figure. As a result, several BTCB vaults were deemed undercollateralized and liquidated almost instantly. This clearly explains why in DeFi one weak point often brings down the entire mechanism. Earlier we wrote about news on regulatory changes in the crypto sector, and such incidents only increase attention to protocol security.

There was no complex magic in this scheme, just one poorly protected price. When the oracle fails, liquidations cascade.

The market reaction was harsh

After the incident, Balance Coin started being sold off almost without pause. At the time the source was published, BLC was already trading at $0,007, but fresh data showed an even worse picture, around $0,000965. This drop does not look like ordinary volatility. The token has effectively lost trust.

There is another strange signal as well. A separate BLC/USDT pool on one DEX platform showed about $0,9866 for 1 BLC, liquidity of $102 857, 97 transactions, and $14 169 in 24-hour volume, while the aggregator itself showed an almost zero price. Such a gap often means the market is split into separate pockets of liquidity rather than trading on one fair benchmark. In such conditions, even a small trade can produce a very different result than the seller or buyer expects. For those following similar crashes, it is also useful to look at our piece on weekly inflows into Ethereum ETFs, because the market behaved very differently there: no shock, but a clear shift in capital.

According to another crypto media outlet, after the drop the number of BLC holders rose to 18,03 thousand as of July 22, but 64,42% of the supply was still concentrated among large holders. This matters. When a token is that concentrated, a few large wallets can move the price significantly even without heavy trading volume.

• BLC lost its peg to the dollar and fell 99.9%.

• Losses from the incident were estimated at $912 000 to $915 000.

• One market aggregator showed a price of about $0,000965 and a daily volume of $103 023.

• The BLC contract lists Solidity v0.5.12, 200 runs, and the label No Contract Security Audit Submitted.

• Separate analysts wrote about the movement of more than 10,73 BTCB and about 761 696 BSC-USD.

• More than 4,5 million BLC passed through one DEX platform, according to analysts’ estimates.

What does this mean for investors?

For holders of algorithmic stablecoins, this case has a very simple takeaway: a peg to the dollar is worthless if the oracle can be hacked or fooled. One module without OSM protection, one weak price check, and the system starts liquidating its own users. In DeFi, this is not theory. It is a direct loss of more than $900 000.

Ukrainian traders should look not only at the price, but also at the technical foundation of the project. If a token depends on a single liquidity pool, a single oracle, or a poorly audited contract, the risk of a sharp collapse is above average. And one more thing: when an asset falls 99.9%, buying “cheap” often means catching not a rebound, but a trap with poor liquidity and dead demand. If you need to quickly cash out BTC into hryvnia, it is convenient to sell Bitcoin to Monobank without unnecessary moves between services.

There is also a broader lesson for the whole market. OWASP, in its Smart Contract Top 10:2026, explicitly classifies price oracle manipulation as a separate risk category and recommends multiple price sources, anomaly filtering, and TWAP. Balance Protocol, apparently, did not have enough resilience in exactly this area. So for an investor, the key issue is not the project’s loud name, but whether it can survive one bad data block.

Frequently asked questions

Why did Balance Coin fall almost to zero?

Because the protocol, according to reports, fell victim to manipulation of the BTCB price in the oracle. As a result, several collateral positions were liquidated, and the attacker likely minted unsecured BLC and sold them for USDT and BTCB.

How much was lost in this incident?

The source estimates losses at $912 000 to $915 000. Separately, analysts described the movement of more than 761 696 BSC-USD and more than 10,73 BTCB, which helps show the scale of the attack.

Could the risk have been spotted in advance?

Yes, partially. The BLC contract is marked as having no submitted security audit, and the architecture itself lacked an OSM, which slows sharp price changes. That is not a guarantee of a hack, but it is already a serious warning sign.

Balance Coin showed how quickly an algorithmic stablecoin can lose everything if its pricing cannot withstand an attack. For those who want to lock in profits or exit a risky asset into hryvnia, it makes sense to look at sell USDT TRC20 to Monobank as a practical option without unnecessary complications.
