## Description

Interact with Jupiter Lend Protocol. Read-only SDK (@jup-ag/lend-read) for querying liquidity pools, lending markets (jlTokens), and vaults. Write SDK (@jup-ag/lend) for lending (deposit/withdraw) and vault operations (deposit collateral, borrow, repay, manage positions).

# Jupiter Lend Protocol

Jupiter Lend (powered by Fluid Protocol) is a lending and borrowing protocol on Solana. It offers **Liquidity Pools**, **Lending Markets (jlTokens)**, and **Vaults** for leveraged positions.

The protocol uses two main SDKs:

- `@jup-ag/lend-read`: Read-only queries for all programs (Liquidity, Lending, Vaults)
- `@jup-ag/lend`: Write operations (deposit, withdraw, borrow, repay)

## Agent usage

Example prompts you can use to demo Jupiter Lend integrations:

- Discover all available vaults and list them
- Fetch all vault positions for a user
- Deposit collateral and borrow in a single transaction
- Repay max debt and withdraw max collateral for a position
- Get user Earn (jlToken) positions and underlying balances
- Build a flashloan for arbitrage or liquidation
- Get liquidity rates and APY for a token
- Create a new vault position (positionId 0), deposit collateral, and borrow

## SDK Installation

```bash
# For read operations (queries, prices, positions)
npm install @jup-ag/lend-read

# For write operations (transactions)
npm install @jup-ag/lend
```

# 1. Key Concepts & Protocol Jargon

Understanding the architecture and terminology of Jupiter Lend will help you build better integrations.

### Architecture: The Two-Layer Model

- **Liquidity Layer (Single Orderbook)**: The foundational layer where all assets reside. It manages token limits, rate curves, and unified liquidity. Users never interact with this directly.
- **Protocol Layer**: User-facing modules (Lending and Vaults) that sit on top of the Liquidity Layer and interact with it via Cross-Program Invocations (CPIs).
