paper airplane Today it announced the launch of its mainnet and Kite Agent Passport, an identity and payment infrastructure designed specifically for autonomous AI agents.
The launch marks Kite’s move from testnet to production, offering a payments and settlement layer specifically designed for agent-driven transactions. The infrastructure combines three layers into one platform: the native stable settlement layer (Kite Chain), the underlying agent service (Kite Agent Passport), and the agent interface and expertise.
Kite Agent Passport provides AI agents with a secure, programmable wallet to hold funds and make purchases on users’ behalf – while users retain full control over spending limits and approved destinations. For example, users can purchase physical items, have them shipped home, and let their agent process payments, all within Cloud, with spending limits imposed by Passport. Kite Chain acts as a stable local settlement layer, processing payments in digital dollars and connecting to traditional banking systems for ordinary consumers. The agent interface and experience allows agents and developers to interact with the system through agent registration, tools, and service discovery.
“The launch is just the beginning,” said Qi Zhang, co-founder and CEO of Kite. “Our mission is to create the trusted backbone of agent-driven economies – where each independent agent operates with a verified identity, programmable permissions, and seamless settlement. This is the infrastructure that will finally allow agents to do everything for you. We’re excited to be building it.”
Now, integrated with more than 90 providers, the platform allows users to explore a wide range of agent payment use cases – from shopping and travel planning to automated agent workflows using agent paid services.
Kite is also positioning itself as a unified center for major payment protocol standards, including the x402 Payment Standard, Google’s AP2 Protocol, Stripe’s Automated Payment Protocol (MPP), and the Anthropic Model Context Protocol (MCP). The company is also a member of the Linux Foundation’s Agentic AI Foundation (AAIF).
Kite has raised $35 million in funding led by PayPal Ventures and General Catalyst. Pilot integrations with PayPal and Shopify are currently underway, expanding Kite’s payment infrastructure to include real-world commerce.
