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

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

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