Korea Upbit locking 98% of coins into cold wallets is already a benchmark for security in the industry. But this only solves the problem of "how to store" them; now there is a more exciting challenge: when AI starts managing and spending money, how should these accounts be calculated?

This is about the recent launch of Kite mainnet. This thing isn’t meant for human use; it’s specifically built as a financial infrastructure for AI agents.

It sounds abstract, but the logic is straightforward — existing blockchains are too "heavy" for AI. You might think a few cents of fee isn’t a big deal, but AI needs to perform hundreds of thousands to millions of micro-payments daily; the costs become astronomical. Kite targets this pain point: transaction confirmations within one second, with per-transaction costs below 0.001 cents. Developers don’t need to learn from scratch; it’s EVM-compatible, so they can get started right away.

How about security? The three-layer identity design is quite clever. You hold the root key, which has the highest permissions; when authorizing an AI assistant, it has its own independent identity and accumulates reputation; for executing specific tasks, it uses temporary keys that are destroyed after use. What does this mean? You can let AI help pay your utilities, but it can’t move other assets in your wallet. Permissions are tightly controlled, enabling machines to truly gain "economic autonomy."

The payment layer is even more aggressive. Kite bets on stablecoins + state channels, allowing AI to perform high-frequency micro-payments frantically. Imagine the scene: every time your AI content assistant generates a piece of copy, it can settle the payment in real-time; every time your data crawler calls an API, it automatically completes the payment — all without human intervention, the machine calculates the bills itself.

This isn’t science fiction; it’s an ongoing infrastructure revolution. When machines start having wallets and spending money, the game rules change.
