## What it does

This skill connects agents to the Jupiter Lend protocol on Solana. Querying markets, jlToken exchange prices, and vault states relies on the `@jup-ag/lend-read` package. Executing deposits, debt repayments, and collateral withdrawals requires `@jup-ag/lend`.

The system uses a two-layer structure. A shared liquidity layer sits at the base, while user-facing lending and vault programs operate above it. Vault positions link directly to user NFT identifiers. All position updates pass through `getOperateIx`, where positive or negative values set the transaction direction.

Parameter values in SDK calls must be passed in smallest token base units. Without installing the respective npm packages beforehand, the agent cannot construct valid on-chain instructions.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add jup-ag/agent-skills --skill jupiter-lend -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/jupiter-lend/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/jupiter-lend/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add jup-ag/agent-skills --skill jupiter-lend -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/jupiter-lend/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add jup-ag/agent-skills --skill jupiter-lend -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/jupiter-lend/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jup-ag/agent-skills jupiter-lend
```

2. **Manually: put the files in place**
- File: `.github/skills/jupiter-lend/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add jup-ag/agent-skills --skill jupiter-lend -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/jup-ag/agent-skills --path skills/jupiter-lend
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/jupiter-lend/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jup-ag/agent-skills --skill jupiter-lend -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- query available lending markets and vault limits on Solana
- inspect user jlToken balances and accrued earnings
- deposit collateral and borrow funds in a single transaction
- repay outstanding debt and withdraw deposited collateral
- construct flashloan instructions for arbitrage opportunities

## Example prompts
- Discover all available Jupiter Lend vaults and list their limits
- Fetch all jlToken positions and underlying balances for this wallet
- Build a transaction to deposit collateral and borrow against it

# 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).

### Terminology

- **jlToken (Jupiter Lend Token)**: The yield-bearing asset you receive when supplying tokens to the Lending protocol (e.g., `jlUSDC`). As interest accrues, the exchange rate increases, making your `jlToken` worth more underlying `USDC`.
- **Exchange Price**: The conversion rate used to translate between "raw" stored amounts and actual token amounts. It continuously increases as interest is earned on supply or accrued on debt.
- **Collateral Factor (CF)**: The maximum Loan-to-Value (LTV) ratio allowed when opening or managing a position.
- **Liquidation Threshold (LT)**: The LTV at which a position becomes undercollateralized and eligible for liquidation.
- **Liquidation Max Limit (LML)**: The absolute maximum LTV limit. If a position's risk ratio exceeds this boundary, it is automatically absorbed by the protocol to protect liquidity providers.
