The Brazilian Securities and Exchange Commission (CVM) requested that Mercado Bitcoin provide it with information on fixed-income tokens the exchange has issued over the past two years.
The CVM wants to know the amount Mercado Bitcoin raised with the tokens and see a list of investors who participated.
Mercado Bitcoin said in a statement that it didn't release "public offerings of securities outside the scope of the authorizations we hold as an authorized crowdfunding platform and investment manager."
In September, the CVM banned the Singapore-based cryptocurrency exchange Bybit from brokering securities, as it argued that only Brazil's stock exchange B3 was allowed to offer such instruments.
CVM plans to release an official crypto guide recommending companies to consult the commission before issuing any token that may be considered a security, CoinDesk learned on Tuesday.
