Chicago-based cryptocurrency exchange EriX is reportedly about to launch its spot trading service, industry news outlet The Block reports on April 24.

Per the report, the exchange has recently been in test mode with some financial firms that would potentially become users. One of those firms is reportedly United States retail brokerage TD Ameritrade, which announced that it invested in ErisX in October of last year. The platform reportedly aims to host spot crypto and crypto derivative trading later this year after obtaining regulatory approval.

According to a report released at the time, investing company DRW Holdings and high-frequency trader Virtu Financial also invested in the exchange. Moreover, both also reportedly agreed to be market makers for ErisX.

According to The Block, TD Ameritrade could soon offer crypto trading to 11 million retail clients. The Block claims that if TD Ameritrade links to ErisX, it would be among the first major brokers to offer cryptocurrency trading, following Robinhood.

In a tweet published on April 23, ErisX declared that a limited number of participants are currently testing the platform.

As Cointelegraph reported earlier this week, Twitter personality Cryptopolis, a quantitative analyst at StrongMarket, tweeted that he bought one bitcoin through an account on retail brokerage firm TD Ameritrade on Nasdaq. Although he later noted that the trade had not gone through, he still alleged that Nasdaq is quietly testing a new bitcoin-based asset that is available only through their Paper Trading platform.

At the beginning of the current month, ErisX has appointed three veterans from Barclays, Youtube and the Chicago Board Options Exchange to fill executive roles at the company.
