Kite has launched its Avalanche-based mainnet and its Agent Passport system to enable autonomous AI agents to execute programmable payments, aiming to reduce friction in machine-driven commerce, according to Messari.
As AI systems shift from answering questions to executing tasks, the next challenge is money—specifically whether AI agents can pay for services on a user’s behalf without creating security and compliance problems. Messari Research analyst Eric Manoukian said Kite is addressing this issue with a vertically integrated “agent payments” stack launched alongside its mainnet.
Manoukian argued that today’s agents can write code, conduct research, and orchestrate workflows, but they often stall when a transaction is required. Many real-world agent use cases—such as premium API calls, data subscriptions, and usage-based services—depend on small, frequent payments. Requiring human approval for each purchase can undermine autonomy and makes payments one of the weakest links in commercializing self-directed AI.
Messari said the bottleneck stems from legacy finance rails being designed for human identity checks and settlement windows rather than machine-to-machine micropayments that may need to clear in milliseconds and run continuously. Blockchains, by contrast, operate 24/7, can settle near real time, and support programmable payment logic—capabilities that align with autonomous software making many small, time-sensitive transactions.
Messari described Kite’s mainnet launch as a shift from testing agent payment flows on a testnet to running them on dedicated infrastructure. The report characterizes Kite’s approach as “full-stack,” bundling a purpose-built blockchain, programmable wallets, identity, and governance into a single system.
In an early market where competitors may focus on individual layers—such as standards, wallets, or settlement—Kite is betting that tight integration can reduce onboarding complexity for developers while giving users clearer control over what an agent can do.
At the center of Kite’s design is the “Kite Agent Passport,” described as both a programmable wallet and an identity system for AI agents. Developers can create a Passport that packages identity, spending permissions, settlement rails, and compatibility with external protocols.
Users can set approved merchants, spending caps, task-specific policies, and emergency shutdown controls, aiming to balance autonomy with guardrails rather than requiring an all-or-nothing approach.
Technically, Kite is built as an Avalanche-based, EVM-compatible Layer 1 blockchain. Messari highlighted a one-second block time and sub-second finality, along with “gas abstraction,” intended to smooth high-frequency, low-value transactions common in agent workloads.
The report argues Kite chose a dedicated L1 rather than adapting a general-purpose chain or relying on Layer 2 rollups, citing the view that additional latency and accumulated overhead can become material when agents call multiple services in parallel and make sequential payments.
Messari said agents can access user-funded stablecoins, check prices, and execute e-commerce and service payments within predefined permissions. Kite has also emphasized integrations with large language model environments such as Claude, enabling purchase approvals inside a chat interface.
The Passport is positioned as more than a typical crypto wallet, combining access management, session keys, and spending controls intended for automated execution.
Kite is entering a crowded and fast-forming competitive environment. Messari cited efforts including Coinbase’s x402 for per-request stablecoin payments over HTTP, Google’s AP2 payment-method-neutral standard, and Stripe and Tempo targeting micropayments through machine payment protocols and payment-focused Layer 1 designs.
Other examples mentioned include Circle’s off-chain aggregation model for USDC “nanopayments” that settles as a single on-chain transaction, Visa’s infrastructure for card payments initiated by AI agents, and Ant Digital Technologies (part of the Ant Group ecosystem) introducing a platform for agent registration, discovery, and payments.
Rather than backing a single standard, Messari said Kite is pursuing native compatibility across multiple emerging protocols, including x402, Google’s AP2, Anthropic’s MCP, and OAuth 2.1. The strategy is to keep final settlement and spend-control logic anchored to Kite’s chain and Passport, using a “many doors, one settlement core” approach while interoperability has not yet converged on one layer.
Messari said Kite assembled launch partners to accelerate distribution. PayPal’s stablecoin PayPal USD (PYUSD) is positioned as a core settlement asset, while Banxa provides fiat on- and off-ramps. The Avalanche Foundation is supporting the mainnet rollout, and LayerZero is set to power cross-chain bridging.
Coinbase is supporting x402 connectivity and exchange-related efforts. Wallet and expansion support is expected from Privy, OKX Wallet, and Bitget Wallet, while Crossmint is connecting agent commerce with merchants via inventory APIs. Messari said the Google relationship focuses on linking identity and commerce standards around AP2 and a broader universal commerce protocol.
Messari also pointed to market interest in Kite’s token. The report said KITE followed a token generation event in November 2025 and listed on major exchanges including Binance, OKX, Upbit, Coinbase, Bitget, and Bybit. It cited a fully diluted valuation of roughly $3 billion by March 2026.
Messari said KITE entered CoinMarketCap’s top 100 and rose as high as seventh by spot volume on Upbit, suggesting the “agent payments” and “AI + blockchain” narrative resonated with traders amid broader volatility.
Messari emphasized that long-term success will depend on usage. Manoukian highlighted early indicators to watch: the number of Passport wallets created, stablecoin settlement volume running through the network, and the number of active agent integrations using Passport “skills.”
For Kite’s thesis to hold, Messari said users must be willing to delegate limited fund access to agents, merchants must accept the channel, and settlement must occur consistently on Kite’s chain. As AI transitions from a productivity tool to an economic actor, Kite is positioning itself at the center of the industry’s first real stress test for “agent payments” infrastructure.
Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
