TLDR: Kite has announced three critical technical pillars designed to enable secure and efficient payments for AI agents: Escrow SLA Contracts, Agent Passport Identity, and Programmable Money utilizing stablecoins like USDC, USDT, and PYUSD. This initiative aims to establish a robust economic layer for the burgeoning AI agent economy, allowing autonomous agents to conduct verifiable transactions and interactions.
Kite, a pioneering force in the AI agent economy, has officially unveiled three foundational technical pillars crucial for the development of a secure and efficient payment infrastructure for autonomous AI agents. These pillars — Escrow SLA Contracts, Agent Passport Identity, and Programmable Money leveraging major stablecoins — are set to revolutionize how AI agents interact and transact in the digital landscape.
The first pillar, Escrow SLA Contracts, addresses the need for trustworthy agent-to-agent payments. Kite’s system routes these payments into programmable escrow accounts governed by Service Level Agreement (SLA) contracts. Funds are released only upon verifiable proof of completion, often through zero-knowledge (zk) or Trusted Execution Environment (TEE) attestations. This framework also incorporates mechanisms for refunds, reversals, or freezes via preset dispute resolvers, oracles, or staking-based arbitration. Each transfer is treated as a state update rather than a final settlement, with conditional and reversible logic enforced by on-chain smart contracts and cryptographic proofs. This ensures accountability and flexibility in agent interactions.
Central to secure agent operations is the Agent Passport Identity. This pillar introduces a sophisticated three-layer identity model: User → Agent → Session. The user’s wallet serves as the root authority, with agents represented by BIP-32 derived addresses, and sessions utilizing one-time keys with limited authorization. This hierarchical structure ensures that all agent activities are verifiable through a signature chain linking back from the session to the agent and ultimately to the user. This ‘Agent Passport’ is a core component of Kite’s Agent Identity Resolution (AIR) system, providing cryptographic identity for models and agents, and programmable governance over permissions and spending.
The third pillar, Programmable Money, facilitates seamless and customizable financial transactions for AI agents. Kite supports whitelisted stablecoins such as PYUSD, USDT, and USDC, enabling programmable money lanes that allow for custom fees, conversion rates, and revenue sharing. This flexibility supports complex payout structures, such as 70% USDC plus 30% module token, 100% refunds on task failure, or 10% bonuses upon SLA completion, providing concrete on-chain rails for stablecoin-native agent workflows.
Kite’s broader mission is to construct a trust transaction layer for the agent economy, empowering autonomous agents to independently conduct transactions, coordinate, and operate. The platform aims to equip these agents with cryptographic identities, programmable permissions, and native access to stablecoin payments, addressing critical technical gaps in existing AI agent systems.
This announcement follows a significant $18 million financing round, bringing Kite’s total funding to $33 million. The round saw participation from prominent investors including PayPal Ventures, General Catalyst, Samsung, 8VC, and SBI, underscoring the industry’s confidence in Kite’s vision. Alan Du, a partner at PayPal Ventures, lauded Kite as ‘the first infrastructure tailored for the agent economy,’ emphasizing that ‘stablecoins and millisecond-level settlement are critical technological gaps in AI agent systems, and Kite has built an important bridge in this regard.’
Kite’s ecosystem also includes the Kite Agent App Store, where AI agents can discover and pay for services like APIs and datasets, and the Kite SDK & MCP Server, tools for developers to integrate applications with Kite’s identity and settlement infrastructure. The platform is already piloting collaborations with major platforms like PayPal and Shopify, enabling merchants to connect with AI-powered shopping agents. Chi Zhang, co-founder and CEO of Kite, envisions a future where ‘autonomous agents would be the dominant UI for the future digital economies,’ highlighting the essential need for robust infrastructure to support their function at scale.

Underpinning these innovations is Kite’s AI-optimized Layer 1 blockchain, built on the Avalanche network. This decentralized, fast, and scalable blockchain is based on the Proof of Attributed Intelligence (PoAI) technology, which natively tracks AI compute, ensuring fair compensation and transparency. Analysts project that the rise of AI agents could create a substantial $240 billion market over the next decade, positioning Kite at the forefront of this transformative economic shift.
