description: Ranger Finance SDK for building perpetual futures trading applications on Solana. The first Solana Perps Aggregator - aggregates liquidity across multiple perp protocols (Drift, Flash, Adrena, Jupiter). Use when integrating perps trading, smart order routing, position management, or building AI trading agents.

Ranger Finance SDK Development Guide

A comprehensive guide for building Solana applications with Ranger Finance - the first perpetual futures aggregator on Solana.

Overview

Ranger Finance is a Smart Order Router (SOR) that aggregates perpetual futures trading across multiple Solana protocols:

• **Drift Protocol**: Leading perps DEX on Solana
• **Flash Trade**: High-performance perpetuals
• **Adrena**: Leverage trading protocol
• **Jupiter Perps**: Jupiter's perpetuals platform

Key Benefits

• **Best Execution**: Automatically routes orders to venues with best pricing
• **Unified API**: Single interface for all supported perp protocols
• **Position Aggregation**: View and manage positions across all venues
• **AI Agent Support**: Built-in MCP server for AI trading agents

Quick Start

Installation (TypeScript)

# Clone the SDK demo
git clone https://github.com/ranger-finance/sor-ts-demo.git
cd sor-ts-demo
npm install

Environment Setup

Create a `.env` file:

RANGER_API_KEY=your_api_key_here
SOLANA_RPC_URL=https://api.mainnet-beta.solana.com
WALLET_PRIVATE_KEY=your_base58_private_key  # Optional, for signing

Basic Setup

import { SorApi, TradeSide } from 'ranger-sor-sdk';
import dotenv from 'dotenv';

dotenv.config();

// Initialize the SOR API client
const sorApi = new SorApi({
  apiKey: process.env.RANGER_API_KEY!,
  solanaRpcUrl: process.env.SOLANA_RPC_URL,
});

// Your wallet public key
const walletAddress = 'YOUR_WALLET_PUBLIC_KEY';

Core Concepts

1. Trade Sides

type TradeSide = 'Long' | 'Short';

2. Adjustment Types

type AdjustmentType =
  | 'Quote'           // Get a quote only
  | 'Increase'        // Open or increase position
  | 'DecreaseFlash'   // Decrease via Flash
  | 'DecreaseJupiter' // Decrease via Jupiter
  | 'DecreaseDrift'   // Decrease via Drift
  | 'DecreaseAdrena'  // Decrease via Adrena
  | 'CloseFlash'      // Close via Flash
  | 'CloseJupiter'    // Close via Jupiter
  | 'CloseDrift'      // Close via Drift
  | 'CloseAdrena'     // Close via Adrena
  | 'CloseAll';       // Close entire position

3. Position Interface

interface Position {
  id: string;
  symbol: string;
  side: TradeSide;
  quantity: number;
  entry_price: number;
  liquidation_price: number;
  position_leverage: number;
  real_collateral: number;
  unrealized_pnl: number;
  borrow_fee: number;
  funding_fee: number;
  open_fee: number;
  close_fee: number;
  created_at: string;
  opened_at: string;
  platform: string;  // 'DRIFT', 'FLASH', 'ADRENA', 'JUPITER'
}

4. Quote Response

interface Quote {
  base: number;
  fee: number;
  total: number;
  fee_breakdown: {
    base_fee: number;
    spread_fee: number;
    volatility_fee: number;
    margin_fee: number;
    close_fee: number;
    other_fees: number;
  };
}

interface VenueAllocation {
  venue_name: string;
  collateral: number;
  size: number;
  quote: Quote;
  order_available_liquidity: number;
  venue_available_liquidity: number;
}

interface OrderMetadataResponse {
  venues: VenueAllocation[];
  total_collateral: number;
  total_size: number;
}

Trading Operations

Get a Quote

Before executing a trade, get a quote to see pricing across venues:

import { SorApi, OrderMetadataRequest, TradeSide } from 'ranger-sor-sdk';

const sorApi = new SorApi({ apiKey: process.env.RANGER_API_KEY! });

async function getQuote() {
  const request: OrderMetadataRequest = {
    fee_payer: walletAddress,
    symbol: 'SOL',
    side: 'Long' as TradeSide,
    size: 1.0,                        // 1 SOL position size
    collateral: 10.0,                 // 10 USDC collateral (10x leverage)
    size_denomination: 'SOL',
    collateral_denomination: 'USDC',
    adjustment_type: 'Quote',
  };

  const quote = await sorApi.getOrderMetadata(request);

  console.log('Available venues:');
  quote.venues.forEach(venue => {
    console.log(`  ${venue.venue_name}: ${venue.quote.total} USDC`);
  });

  return quote;
}

Open/Increase a Position

async function openLongPosition() {
  const request = {
    fee_payer: walletAddress,
    symbol: 'SOL',
    side: 'Long' as TradeSide,
    size: 1.0,
    collateral: 10.0,
    size_denomination: 'SOL',
    collateral_denomination: 'USDC',
    adjustment_type: 'Increase' as const,
  };

  // Get transaction instructions
  const response = await sorApi.increasePosition(request);

  console.log('Transaction message (base64):', response.message);

  if (response.meta) {
    console.log('Executed price:', response.meta.executed_price);
    console.log('Venues used:', response.meta.venues_used);
  }

  return response;
}

// Open a short position
async function openShortPosition() {
  const request = {
    fee_payer: walletAddress,
    symbol: 'ETH',
    side: 'Short' as TradeSide,
    size: 0.5,
    collateral: 100.0,
    size_denomination: 'ETH',
    collateral_denomination: 'USDC',
    adjustment_type: 'Increase' as const,
  };

  return await sorApi.increasePosition(request);
}

Decrease a Position

async function decreasePosition() {
  const request = {
    fee_payer: walletAddress,
    symbol: 'SOL',
    side: 'Long' as TradeSide,
    size: 0.5,                        // Decrease by 0.5 SOL
    collateral: 5.0,                  // Withdraw 5 USDC collateral
    size_denomination: 'SOL',
    collateral_denomination: 'USDC',
    adjustment_type: 'DecreaseFlash' as const,  // Route through Flash
  };

  return await sorApi.decreasePosition(request);
}
