Identity, governance, and stablecoin rails for agentic payments
Overview
This summary uses submitted and public product material. Only source-mapped claims are documentation reviewed.
Kite is building payment infrastructure for autonomous agents on top of an agent-first blockchain stack. The current platform emphasizes cryptographic identity, programmable governance, stablecoin-native payments, and x402-compatible agent-to-agent transaction flows.
Listing decision
Kite Agent Passport treats the autonomous agent as a first-class identity and payment participant, with delegated budgets and session rules that govern the agent’s own transactions.
Before you choose
Agents that need user-authorized budgets for paid APIs, services, transfers, or purchases using stablecoin and machine-payment rails.
A user must fund the Passport and approve each scoped spending session with a passkey before the agent can spend; card-based payments require a separate issuer onboarding and identity-verification path.
No public Kite Agent Passport fee schedule or plan page was found in the reviewed first-party sources, so product pricing remains unknown; wallet funding and third-party transaction costs do not establish Kite’s own fees.
