Coinbase’s GDAX cryptocurrency exchange has decided to allow customers affected by the ether price crash last week to restore the value of their ETH/USD account.

On 21 June 2017, a multimillion dollar market sell placed on the GDAX ETH-USD order book resulted into a book slippage of 29.4%. This slippage triggered a cascade of about 800 stop loss orders and margin funding liquidations, driving ETH to temporarily trade as low as $0.10.

In an update posted on June 21, GDAX said that its investigations revealed no foul play, adding that its matching engine operated as intended throughout this event.

However, in a second update posted on June 24, GDAX noted that some customers “did not receive the quality of service we strive to provide and we want to do better.” It added:

“We will establish a process to credit customer accounts which experienced a margin call or stop loss order executed on the GDAX ETH-USD order book as a direct result of the rapid price movement at 12.30pm PT on June 21, 2017. This process will allow affected customers to restore the value of their ETH-USD account to the equivalent value of their ETH-USD account at the moment prior to the rapid price movement.”

It further clarified that customers who had their margin calls or stop loss orders executed will be credited using company funds, while those customers who had buy orders executed, no trades will be reversed.
