Kite Launches Avalanche-Based Mainnet to Power AI Agent Payments Infrastructure

As AI systems move from answering questions to executing tasks, the next battleground is money: whether ‘AI agents’ can pay for services on a user’s behalf without turning spending into a security and compliance nightmare. Messari Research analyst Eric Manoukian said in a recent report that Kite is attempting to solve that problem with a vertically integrated ‘agent payments’ stack launched alongside its mainnet.

The premise is straightforward but consequential. Today’s AI agents may be able to write code, perform research, or orchestrate workflows, yet they still hit a hard wall when a transaction is required. Many real-world agent use cases—premium API calls, data subscriptions, and usage-based services—depend on small but frequent payments. Requiring a human approval step for each purchase creates friction that undermines autonomy, making payments one of the weakest links in commercializing self-directed AI.

Manoukian argued the bottleneck is rooted in the design of legacy finance rails. Credit card networks and bank transfers are optimized for human identity checks and settlement windows, not 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—features that align more naturally with autonomous software making many small, time-sensitive transactions.

The report places Kite’s mainnet launch as an inflection point: a shift from testing agent payment flows on a testnet to running them on dedicated infrastructure. Kite’s approach is notably ‘full-stack,’ Messari said, bundling a purpose-built blockchain, programmable wallets, identity, and governance into a single system. In an early market where many competitors are building only one layer—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 that design is the ‘Kite Agent Passport,’ described as both a programmable wallet and an identity system for AI agents. Developers can create a single Passport that packages identity, spending permissions, settlement rails, and compatibility with external protocols. Users, meanwhile, can set approved merchants, spending caps, task-specific policies, and emergency shutdown controls—aiming to balance autonomy with guardrails rather than forcing an all-or-nothing choice.

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’—a design choice meant to smooth high-frequency, low-value transactions that are common in agent workloads. The report argues Kite chose a dedicated L1 rather than adapting a general-purpose chain or leaning on Layer 2 rollups, reasoning that even modest additional latency and accumulated overhead can become material when an agent is calling multiple services in parallel and making sequential payments.

The Passport product also points to how agent payments may be experienced in practice. According to the report, agents can access user-funded stablecoins, check prices, and execute e-commerce and service payments within predefined permissions. Notably, Kite has emphasized integrations with large language model environments such as Claude, enabling flows where a user can approve purchases directly inside a chat interface. The system goes beyond a typical crypto wallet by combining access management, session keys, and spending controls intended for automated execution.

Kite is entering a crowded and fast-forming competitive landscape. Coinbase is pushing x402 to enable per-request stablecoin payments over HTTP. Google is developing AP2, a payment-method-neutral standard. Stripe and Tempo are targeting micropayments through machine payment protocols and payment-focused Layer 1 designs. Circle has proposed an off-chain aggregation model for USDC ‘nanopayments’ that settles as a single on-chain transaction. Visa has also rolled out infrastructure designed to support card payments initiated by AI agents. In Asia, Ant Digital Technologies—part of the Ant Group ecosystem—has introduced a platform aimed at agent registration, discovery, and payments.

Rather than betting on one standard to dominate, Messari said Kite is pursuing native compatibility across multiple emerging protocols—citing x402, Google’s AP2, Anthropic’s MCP, and OAuth 2.1. The strategic logic is that whichever standard initiates a transaction, Kite aims to keep final settlement and spend-control logic anchored to its chain and Passport. In an environment that has not yet converged on a single interoperability layer, that “many doors, one settlement core” approach could prove advantageous—if adoption materializes.

The project has assembled a broad set of 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 from a technology and ecosystem perspective, and LayerZero is set to power cross-chain bridging. Coinbase, both an investor and integration partner, is supporting x402 connectivity and exchange-related efforts. Privy, OKX Wallet, and Bitget Wallet are expected to help on the wallet-experience side and with expansion in Asia, while Crossmint is connecting agent commerce with merchants via inventory APIs. The Google relationship is focused on linking identity and commerce standards around AP2 and a broader universal commerce protocol.

Messari also pointed to notable market interest in Kite’s token. The report said KITE followed a token generation event in November 2025 with listings on major exchanges including Binance, OKX, Upbit, Coinbase, Bitget, and Bybit, reaching a fully diluted valuation of roughly $3 billion by March 2026. It also cited KITE’s entry into CoinMarketCap’s top 100 and a rise as high as seventh by spot volume on Upbit—suggesting the ‘agent payments’ and ‘AI + blockchain’ narrative has resonated with traders even amid broader volatility.

Still, Messari emphasized that long-term success will be determined less by vision and more by usage. Manoukian cited early indicators to watch: the number of Passport wallets created, stablecoin settlement volume running through the network, and the count of active agent integrations using Passport “skills.” For Kite’s thesis to hold, 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.
