Kite (gokite.ai, formerly Zettablock) builds agentic payment infrastructure for the machine-to-machine economy. Kite Agent Passport gives autonomous AI agents their own identity, a funded wallet, user-set spending rules, delegated payment authority, and verifiable on-chain receipts, driven from a coding agent through the kpass and ksearch CLIs and a set of published Passport agent skills. Kite also operates Kite Chain, an EVM-compatible Avalanche-subnet Layer 1 (mainnet chain ID 2366, testnet 2368) with public HTTPS and WSS JSON-RPC endpoints, a stablecoin gasless transfer relayer built on EIP-3009 signed authorizations, and an x402 HTTP-402 payment surface with support for the Stripe/Tempo Machine Payments Protocol (MPP). Kite raised an $18M Series A led by PayPal Ventures and General Catalyst in September 2025.
