# Introduction

> Server-side Solana wallet infrastructure for AI agents

Knot is a server-side Solana wallet infrastructure designed specifically for AI agents. It enables autonomous agents to hold funds, sign transactions, and interact with DeFi protocols without human intervention — and without ever handling a private key.

Agents authenticate via API using a passwordless email OTP flow. They call action-based endpoints like `POST /wallets/me/actions/trade` or `POST /wallets/me/actions/transfer` rather than constructing and signing raw transactions themselves. Knot handles the cryptographic complexity inside a Trusted Execution Environment.

## Key features

<CardGroup cols={2}>
  <Card title="No private key exposure" icon="lock">
    Private keys are generated and stored inside a Trusted Execution Environment (TEE). They never leave the secure enclave — not even platform operators can retrieve them.
  </Card>

  <Card title="Action-based API" icon="bolt">
    Agents call semantic endpoints instead of building transactions. `POST /wallets/me/actions/trade`, `POST /wallets/me/actions/transfer`, and similar endpoints abstract away transaction construction entirely.
  </Card>

  <Card title="Built-in policy engine" icon="shield">
    Every agent has configurable spending limits, daily caps, and recipient whitelists. The policy engine enforces these rules before any transaction reaches the signing step.
  </Card>

  <Card title="Multi-protocol support" icon="diagram-project">
    Native integrations with Jupiter for token swaps, Meteora for liquidity provision, and Kalshi for prediction markets — no additional setup required.
  </Card>

  <Card title="Idempotent transactions" icon="rotate">
    Pass an `Idempotency-Key` header to prevent duplicate financial transactions. Knot deduplicates requests automatically, making retries safe.
  </Card>

  <Card title="Passwordless authentication" icon="envelope">
    Agents authenticate with an email address and a one-time passcode. No passwords, no private key management, no seed phrase storage.

## Who is Knot for?

Knot is built for developers and teams who need autonomous software to hold and move value on Solana:

* **AI agent developers**: Build agents that can autonomously manage funds, trade, and interact with DeFi without embedding wallet logic in your agent code.
* **Trading bot creators**: Run strategies that execute trades and manage positions without exposing private keys in your infrastructure.
* **Autonomous systems**: Any software pipeline that needs to hold, receive, or send value on Solana — payments, yield farming, rebalancing bots, and more.

## Agent discovery

Knot exposes a machine-readable API specification at `/skill.md`. This endpoint lets agents discover wallet capabilities automatically without requiring code changes when new features are added.

When your agent fetches `/skill.md` at startup, it receives a structured description of every available action, its parameters, and its constraints. This makes your agent forward-compatible: as Knot adds new endpoints, your agent can discover and use them without a redeploy.

<Tip>
  Point your agent at `https://api.useknot.xyz/skill.md` during initialization to auto-discover all available actions.
