The U.S. Securities and Exchange Commission issued a “no action” letter to DoubleZero on Monday, effectively blessing the project’s 2Z token days before its debut on Solana. In a statement, the Commission said that it “will not recommend [an] enforcement action” against DoubleZero, which was established last year, and is building a high-performance fiber-optic network for blockchains while using tokens to incentivize participants.
