Kite Mainnet officially launched, introducing a Payments Layer for the Agent economy

BlockBeats News, April 30 — For the AI Agent economy, the payment infrastructure Kite announced that its mainnet is officially live, with the launch period covered by Kite Treasury paying network fees, so users do not need to perceive gas.

Along with the mainnet, Kite Agent Passport, which is open to the public, has also been launched as the authorization and payment control layer for Agents. Users can sign a session with control boundaries (including single transaction limit, total budget, validity period, permitted assets, and payment methods) using a passkey. The Agent autonomously executes tasks within these constraints without needing to give the Agent access to bank accounts, credit cards, or private keys. All actions are logged into a unified activity log, which can be audited at any time.

Kite adopts a “three-layer integrated” architecture: the bottom settlement layer is an EVM-compatible L1 that natively supports stablecoin settlement, targeting high-frequency, low-value, Agent-driven payment scenarios; the middle core Agent service layer is hosted by Passport for identity, delegation, and risk control; the top Agent interface layer allows mainstream Agents to connect directly during runtime.

On the application level, use cases for online shopping are now live, with paid API calls settled via the x402 protocol. The Kite team explicitly states that they are not chasing TVL, and will measure progress based on three metrics: total transaction count, monthly active Passports, and total settlement amount.

Currently, users can register an account at agentpassport.ai, register Agents, and initiate delegated authorizations with boundaries. The first batch supports scenarios such as automated online shopping, paid API calls, and multi-step tasks across services.
