On March 5, Polkadot‘s DOT experienced a flash crash at Binance perpetual futures that resulted in the contract trading as low at $0.20. While this could have been an honest fat-finger trading mistake, a number of indicators point to a planned attack.
While no hard evidence will likely ever emerge, the open interest increase just 24 hours ahead of the event indicates that an attacker could have generated an $8.3-million profit by manipulating Binance’s matching engine.

As demonstrated previously, throughout the three-minute candle, $20.4 million value DOT contracts exchanged. Even though the swift disadvantage move was a 99.5percent flash accident, it didn’t lead to cascading liquidations.
Futures contracts liquidations are calculated with the cost of area exchanges. Therefore, a flash-crash entirely on futures costs wouldn’t affect most dealers. In accordance with Binance:
“The Price Index is a bucket of prices from the major Spot Market Exchanges, weighted by their relative volume.”
According to Binance’s support site, Polkadot coin-margined futures index cost consists of both Kraken (DOT/ / USD), Binance (DOT/ / USD), Binance (DOT/BTC), OKEx (DOT/BTC) and also Huobi’s (DOT/ / / BTC) marketplace.
It might be well worth noting that this particular arrangement is coin-margined rather than the liquid Tether-settled one. Cointelegraph recently examined those gaps , saying the Tether-based contract “doesn’t need an active hedge to protect collateral (margin) exposure, thus it’s a better choice for retail traders.”
Data finds the proposed ‘attack’
For the attacker to install this transaction, the very first step is constructing a extended long standing whilst concurrently creating short exposure working with an additional account.
To make a flash accident when risking the minimal amount possible, rather, this event should take place more than a few days before the projected ‘attack.’

As represented above, DOT/ / USD endless futures open curiosity climbed from 1.92 million DOT into 3.34 million several 30 hours before the flash accident, equal to a $47-million rise.
To distinguish the assault against a routine leveraged-long, an individual needs to monitor the long-to-short ratio. ) To maximize profits by the flash accident, the attacker could have generated a considerably greater short leveraged sum, thus influencing the long-to-short ratio.

The information above shows the typical 4.25 ratio exerts longs was seriously affected through the open rate growth. This could confirm the concept of a coordinated assault.
How the transaction is executed
By holding a substantially larger internet short position if both balances are united, the attacker could benefit from a flash accident. All this thing should commence the event would be to advertise sell the net long standing. This movement would activate a large sell arrangement, crashing the futures contract. ) Meanwhile, another account, formerly web brief, would score large.
At a $26.73 moderate cost, 762,000 DOT contracts exchanged throughout the three-minute flash-crash candle. Taking into consideration the shift at the long-to-short ratio, the assault probably generated a $30-million lengthy standing. The secondary accounts held a $10-million web short exposure.
Though far by the 99.5% cost accident, this 19% fall in $33 probably created a $9.5-million profit for the accounts holding the 10-million short-term if 5x leverage has been play. On the flip side, the security lost for its 30-million long standing amounts to $1.2 million should 25x leverage has been deployed.
It is crucial to highlight that holders of Binance DOT futures contracts were improbable influenced by the flash accident. Thus, the attackers’ web long account ought to be holding a unfavorable equilibrium, and also the Binance insurance finance will probably pay for.
The above calculations are only speculations according to exchange-provided data. As mentioned before, it’s not likely that hard proof of the attack could possibly surface.
