A group of U.S. lawmakers are asking Securities and Exchange Commission (SEC) chairman Jay Clayton to clarify when initial coin offerings (ICOs) are considered securities sales.

In the letter

, Representatives Ted Budd, Warren Davidson, Tom Emmer and Darren Soto, along with 11 co-signers, request that Clayton clarify how it is approaching token sales, saying that "current uncertainty surrounding the treatment of offers and sales of digital tokens is hindering innovation in the United States and will ultimately drive business elsewhere."

The letter continues, saying:

As such, the letter continues, the lawmakers are asking the SEC to clarify when token sales should be classified as "investment contracts," whether a token sold as a security can later become a non-security and what tools are available for the "SEC to offer more concrete guidance to innovators."

The letter does not provide a timeline, noting that "such guidance will, reasonably, take time, caution and deep consideration." As such, the letter says the questions are aimed at providing formal guidance in the long-term.

Friday's letter comes just days after Davidson hosted a forum in Washington, D.C. asking leaders in the cryptocurrency space to express any grievances they had with regulations in the U.S.

During the forum, multiple representatives from blockchain startups, cryptocurrency exchanges and venture capital funds emphasized the need for clarity around token sales.

While the SEC has, to date, focused on enforcement actions against malicious actors, CoinList general counsel Georgia Quinn noted that these actions have not provided a clear explanation of what is allowable within the U.S.

This lack of clarity has pushed businesses to leave the nation outright, said Joyce Lai from ConsenSys.
