Kraken, a San Francisco-based digital currency exchange, has announced that it is offering Ether (ETH) Dark Pool trading to its clients, allowing them to place large ether orders discreetly.

Clients will now have access to 6 ether dark pool currency pairs, with the option to exchange ether for bitcoin (ETH/XBT.d), euro (ETH/EUR.d), United States dollar (ETH/USD.d), Canadian dollar (ETH/CAD.d), pound sterling (ETH/GBP.d), and Japanese yen (ETH/JPY.d). Ether Dark Pool trading fees range from 0.20% to 0.36%, depending on trade volume.

Ether’s rapid rise in popularity was cited by Kraken as the reason that led it to introduce this feature. With market cap over $750 million, Ether is currently the second most valuable form of cryptocurrency behind only bitcoin.

Kraken has offered dark pool trading for bitcoin since June 2015 and has become the first and the only exchange to offer Ether Dark Pool trading. CEO Jesse Powell said that for Dark Pool trading, traders need to place orders for a minimum of 50 bitcoins or 2500 ether.

“Kraken is proud to be the first exchange to provide clients with a Dark Pool for ether, a strategic option for professional traders. This year, trading volume for ether has dramatically increased on Kraken’s exchange, and we developed the Ether Dark Pool to bridge the gap between our lit order books and over-the-counter desk,” said Powell.

In addition, Kraken also announced major enhancements to its industry leading Margin Trading program, with increased leverage for ETH/XBT (up from 2.5x to 4x) and the addition of support to three pairs: ETH/EUR, XBT/USD and ETH/USD, all with up to 3x leverage. Ether will also become a collateral currency, meaning that now a client’s ETH balance can be used (in addition to XBT, EUR, and USD) as collateral for the advanced (borrowed) funds tied to a leveraged margin trade. Margin trading remains unavailable to US residents at this time.

“The details get technical but there are two important takeaways when it comes to dark pool and margin trading. If traders are looking to move large sizes without affecting the market, they trade dark on Kraken. If traders want to keep fewer assets on account and they want less exposure to funding delays, they trade with margin on Kraken. These services together with our OTC desk reflect the growing professionalism of our client base and our exchange”, Powell added.

The announcements follow Kraken’s new Position Settlement feature that went live on May 4. It allows clients to return the advanced (borrowed) funds tied to a leveraged margin trade and close a position by sourcing the funds from their own account balance. Previously only available on Kraken manually, Position Settlement is now a free, automated service which eliminates the impact of funding latency on trading.
