In the crypto world over the years, I've seen many people fall into traps just for the sake of convenience. A friend once excitedly showed me his so-called perfect setup—single wallet, a pair of private keys, an app, plus an automated trading bot. He thought this arrangement was clean and visually pleasing. I nodded along with a smile, but inwardly I was a bit uneasy.

Because I understand very well: when assets and code are intertwined, simplicity becomes the most luxurious cost.

A week later, he sent me a message late at night, his voice surprisingly calm—his bot had signed some things without his authorization, acting smartly on its own. The problem wasn't the bot itself, but that the permission settings were too lax. It was like having a master key that opens all doors; once lost, the entire assets could be exposed.

This lesson made me particularly appreciate the concept of identity separation proposed by the KITE(KITE project)—not just because it sounds high-end and impressive, but because it’s like paying tuition with real gold and silver. Who wants to pay again?

Traditional methods are essentially a single key system. Giving this key to any proxy, script, third-party plugin, or even your semi-conscious self is equivalent to handing over all decision-making power. Unlike borrowing something that can be returned, once permissions are abused, there's no turning back.

KITE’s solution breaks down identity into three levels: user layer, proxy layer, and session layer. Three keys, three permission levels, dividing risks layer by layer.

The user layer is you, the highest-level root key. It should be operated as little as possible, like a property deed that remains securely locked. Its main responsibility is to set rules—defining who can do what and to what extent, acting as the final check. The remaining execution rights are delegated downward, with each layer’s permissions strictly limited to specific scopes. This way, even if one part goes wrong, the damage is localized and won't affect the whole.
