- Kite Chain (Layer-1) + stablecoin rails; integrates x402 / AP2 / MCP envelopes
- core_mechanism
- Kite provides agent payment-and-identity infrastructure: Kite AIR gives agents verifiable identities (Agent Passport) and a hierarchical identity model with mathematical delegation; the SPACE framework adds stablecoin-native sub-cent payments with instant finality, cryptographically enforced programmable constraints (smart contracts), immutable audit trails, and economically viable micropayments. It uses x402 as the interoperability envelope between agents and services, with AP2 specializing the flow for stablecoin settlement and MCP for tool access.

- Running autonomous agents that hold verifiable identities and spend within cryptographically enforced limits using stablecoin micropayments.
- when_to_use
- When you need agent identity, delegation, spend guardrails, and stablecoin rails together on a purpose-built network.
- when_not_to_use
- When a single open payment protocol (x402) or mandate framework (AP2) on existing rails meets your need without a dedicated chain.
- code_example
- // Kite Agent Passport + x402 (schematic) // passport = kite.air.issue({ owner, limits: { perTx: '$0.50', daily: '$20' } }) // agent pays via x402 envelope; constraints enforced on-chain by Kite Chain
