Cardano founder Charles Hoskinson has expressed strong support for the upcoming x402 upgrade and the ongoing development of the Leios project. The x402 upgrade, developed by Coinbase and integrated into AP2, simplifies resource payments via API by eliminating the need for registration or complex signatures. Hoskinson described this advancement as 'very big for Cardano.' In addition, Input Output has announced that the Leios project, a significant redesign of Cardano's consensus mechanism, is moving from the research phase to engineering. This transition marks a critical step in enhancing Cardano's blockchain capabilities. Furthermore, Cardano (ADA) has been included in the Grayscale CoinDesk Crypto 5 ETF (GDLC), the first multi-asset crypto ETF in the United States.
