Input Output Global (IOG), the company responsible for developing the Cardano blockchain, has responded to the U.S. Securities and Exchange Commission's (SEC) recent claim that Cardano's native token, ADA, is a security. IOG has denied the SEC's allegations and stated that ADA is not a security under U.S. securities laws.

The SEC has filed lawsuits against Binance and Coinbase for allegedly offering unregistered securities, and has classified several prominent cryptocurrencies, including Cardano (ADA), Solana (SOL), and Polygon (MATIC), as unregistered securities.

IOG has expressed concern about the lack of understanding of decentralized blockchains and emphasized the importance of developing responsible legislation in collaboration with regulators.
