Kite launches its mainnet and rolls out AI Agent authorization payment controls layer

According to Kite’s official announcement, the AI Agent economy payment infrastructure Kite officially launched its mainnet on April 30. During the mainnet launch period, Kite Treasury covers network fees, and users do not need to perceive gas. Kite also opened Kite Agent Passport to the public, serving as the Agent authorization and payment control layer.

Mainnet technical architecture

According to Kite’s official announcement, Kite adopts a “three-in-one” architecture, with the mainnet built on top of the Avalanche network:

Settlement layer: EVM-compatible L1, with native support for stablecoin settlement, targeting high-frequency, low-amount, Agent-driven payment scenarios

Agent service layer: carried by Agent Passport for identity verification, delegated authorization, and risk control

Agent interface layer: allows mainstream Agents to connect directly when running

Detailed breakdown of Kite Agent Passport features

According to Kite’s official announcement, Kite Agent Passport allows users to use a passkey to one-time sign a session with a controlled boundary, with content covering per-transaction limits, total budget, validity period, allowed assets, and payment methods. Within the above constraints, the Agent independently executes tasks without needing to obtain the user’s bank account, credit card, or private keys. All operations are recorded in a unified activity log and support audits at any time.

According to Kite’s official announcement, users can complete account registration, Agent registration, and boundary-scoped delegated authorization on the agentpassport.ai website.

Live application scenarios and metrics

According to Kite’s official announcement, current live application scenarios include online shopping and paid API calls settled via the x402 protocol. The initial batch also supports Agents autonomously executing multi-step tasks across services.

According to Kite’s official announcement, Kite explicitly stated that it does not use TVL (total value locked) as the primary evaluation metric, and will publicly track progress using the following three metrics: total number of transactions, monthly active Passport numbers, and total settlement amount.
