According to BlockBeats, Kite, a payment infrastructure for AI agents, launched its mainnet on April 30, introducing the Agent Passport authorization layer. During the initial phase, the Kite Treasury covers network fees for users. The Passport allows users to authorize agents with defined spending limits, budgets, validity periods, and approved assets through passkey-based sessions, eliminating the need to share private keys or bank details. Kite operates on a three-layer architecture: an EVM-compatible L1 settlement layer supporting stablecoin payments, an Agent service layer powered by Passport, and an Agent interface layer enabling runtime integration.
