# 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.
