# DFlow - Complete Integration Guide

The definitive guide for integrating DFlow - a trading protocol that enables traders to exchange value across spot and prediction markets natively on Solana.

## What is DFlow?

DFlow is a comprehensive trading infrastructure that provides:

- **Trading Applications & Wallets** - Token swaps with intelligent routing and 99.9% token coverage
- **Exchanges & Aggregators** - Access to billions in monthly routed volume across DEXes and Prop AMMs
- **Financial Institutions & Market Makers** - Programmable execution layers with CLPs and async trades
- **Prediction Market Platforms** - Discovery, pricing, routing, and settlement infrastructure

### Key Capabilities

| Feature | Description |
|---------|-------------|
| Token Coverage | 99.9% with millisecond detection |
| Infrastructure | Globally distributed, high-throughput optimization |
| Execution | Advanced algorithms with JIT routing for best-price execution |
| Markets | Support for both spot and prediction market trading |
| MEV Protection | Enhanced sandwich protection with Jito bundles |

## API Overview

DFlow provides two main API categories:

### 1. Swap API (Trading)
**Base URL:** `https://quote-api.dflow.net`

For executing trades:
- **Imperative Swaps** - Full control over route selection at signature time
- **Declarative Swaps** - Intent-based swaps with deferred route optimization
- **Trade API** - Unified interface for spot and prediction market trading
- **Order API** - Quote and transaction generation

### 2. Prediction Market Metadata API
**Base URL:** `https://api.prod.dflow.net`

For querying prediction market data:
- **Events API** - Query prediction events and forecasts
- **Markets API** - Get market details, orderbooks, outcome mints
- **Trades API** - Historical trade data
- **Live Data API** - Real-time milestones and updates
- **WebSocket** - Streaming price and orderbook updates

### Authentication
Most endpoints require an API key via the `x-api-key` header. Contact `hello@dflow.net` to obtain credentials.

## Quick Start

### Imperative Swap (3 Steps)

```typescript
import { Connection, Keypair, VersionedTransaction } from "@solana/web3.js";

const API_BASE = "https://quote-api.dflow.net";
const API_KEY = process.env.DFLOW_API_KEY; // Optional but recommended

// Token addresses
const SOL = "So11111111111111111111111111111111111111112";
const USDC = "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v";

async function imperativeSwap(keypair: Keypair, connection: Connection) {
  // Step 1: Get Quote
  const quoteParams = new URLSearchParams({
    inputMint: SOL,
    outputMint: USDC,
    amount: "1000000000", // 1 SOL
    slippageBps: "50",    // 0.5%
  });

  const quote = await fetch(`${API_BASE}/quote?${quoteParams}`, {
    headers: API_KEY ? { "x-api-key": API_KEY } : {},
  }).then(r => r.json());

  // Step 2: Get Swap Transaction
  const swapResponse = await fetch(`${API_BASE}/swap`, {
    method: "POST",
    headers: {
      "content-type": "application/json",
      ...(API_KEY && { "x-api-key": API_KEY }),
    },
    body: JSON.stringify({
      userPublicKey: keypair.publicKey.toBase58(),
      quoteResponse: quote,
      dynamicComputeUnitLimit: true,
      prioritizationFeeLamports: 150000,
    }),
  }).then(r => r.json());

  // Step 3: Sign and Send
  const tx = VersionedTransaction.deserialize(
    Buffer.from(swapResponse.swapTransaction, "base64")
  );
  tx.sign([keypair]);

  const signature = await connection.sendTransaction(tx);
  await connection.confirmTransaction(signature);

  return signature;
}
```

### Trade API (Unified - Recommended)

The Trade API provides a single endpoint that handles both sync and async execution:

```typescript
async function tradeTokens(keypair: Keypair, connection: Connection) {
  // Step 1: Get Order (quote + transaction in one call)
  const orderParams = new URLSearchParams({
    inputMint: SOL,
    outputMint: USDC,
    amount: "1000000000",
    slippageBps: "50",
    userPublicKey: keypair.publicKey.toBase58(),
  });

  const order = await fetch(`${API_BASE}/order?${orderParams}`, {
    headers: API_KEY ? { "x-api-key": API_KEY } : {},
  }).then(r => r.json());

  // Step 2: Sign and Send
  const tx = VersionedTransaction.deserialize(
    Buffer.from(order.transaction, "base64")
  );
  tx.sign([keypair]);
  const signature = await connection.sendTransaction(tx);

  // Step 3: Monitor (based on execution mode)
  if (order.executionMode === "async") {
    // Poll order status for async trades
    let status = "pending";
    while (status !== "closed" && status !== "failed") {
      await new Promise(r => setTimeout(r, 2000));
      const statusRes = await fetch(
        `${API_BASE}/order-status?signature=${signature}`,
        { headers: API_KEY ? { "x-api-key": API_KEY } : {} }
      ).then(r => r.json());
      status = statusRes.status;
    }
  } else {
    // Sync trades complete atomically
    await connection.confirmTransaction(signature);
  }

  return signature;
}
```

## Swap Modes Comparison

| Feature | Imperative | Declarative |
|---------|------------|-------------|
| Route Control | Full control at sign time | Optimized at execution |
| Latency | Higher (two API calls) | Lower (deferred calc) |
| Slippage | Fixed at quote time | Minimized at execution |
| Sandwich Protection | Standard | Enhanced |
| Use Case | Precise route requirements | Best execution priority |

### When to Use Imperative
- Need to review exact route before signing
- Building order books or specific DEX routing
- Complex multi-step transactions
- Need deterministic execution paths

### When to Use Declarative
- Prioritize best execution
- Lower slippage requirements
- Simple token swaps
- MEV protection is important

## Execution Modes

### Synchronous (Atomic)
- Single transaction execution
- All-or-nothing settlement
- Standard confirmation flow
- Use `connection.confirmTransaction()`

### Asynchronous (Multi-Transaction)
- Uses Jito bundles
- Open → Fill → Close transaction flow
- Poll `/order-status` for completion
- Better for complex routes or prediction markets

```typescript
// Async order monitoring
async function monitorAsyncOrder(signature: string) {
  const statuses = ["pending", "open", "pendingClose"];
  let currentStatus = "pending";

  while (statuses.includes(currentStatus)) {
    await new Promise(r => setTimeout(r, 2000));

    const res = await fetch(
      `${API_BASE}/order-status?signature=${signature}`,
      { headers: { "x-api-key": API_KEY } }
    ).then(r => r.json());

    currentStatus = res.status;

    if (currentStatus === "closed") {
      return { success: true, fills: res.fills };
    }
    if (currentStatus === "failed" || currentStatus === "expired") {
      return { success: false, status: currentStatus };
    }
  }
}
```

## Prediction Markets

DFlow provides infrastructure for trading prediction market outcome tokens.

### Market Structure
```
Series (Collection)
  └── Event (Occurrence)
        └── Market (Outcome Trade)
```

### Market Lifecycle
1. **Initialized** - Market created
2. **Active** - Trading enabled
3. **Inactive** - Trading paused
4. **Closed** - No more trading
5. **Determined** - Outcome known
6. **Finalized** - Payouts available

### Trading Prediction Markets
```typescript
// Use the Trade API with prediction market token mints
const order = await fetch(`${API_BASE}/order?${new URLSearchParams({
  inputMint: USDC,
  outputMint: OUTCOME_TOKEN_MINT, // Prediction market token
  amount: "10000000", // 10 USDC
  slippageBps: "100",
  userPublicKey: keypair.publicKey.toBase58(),
  predictionMarketSlippageBps: "200", // Separate slippage for PM
})}`, { headers: { "x-api-key": API_KEY } }).then(r => r.json());
```

## Common Token Mints

| Token | Mint Address |
|-------|--------------|
| SOL (Wrapped) | `So11111111111111111111111111111111111111112` |
| USDC | `EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v` |
| USDT | `Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB` |

| JUP | `JUPyiwrYJFskUPiHa7hkeR8VUtAeFoSYbKedZNsDvCN` |
| WIF | `EKpQGSJtjMFqKZ9KQanSqYXRcF8fBopzLHYxdM65zcjm` |

## Priority Fees

Configure transaction priority:

```typescript
// Option 1: Auto (recommended)
prioritizationFeeLamports: "auto"

// Option 2: Priority level
prioritizationFeeLamports: {
  priorityLevel: "high" // "medium", "high", "veryHigh"
}

// Option 3: Exact amount
prioritizationFeeLamports: 150000

// Option 4: Max with auto-adjust
prioritizationFeeLamports: {
  autoMultiplier: 2,
  maxLamports: 500000
}
```

## Error Handling

```typescript
async function safeSwap(params: SwapParams) {
  try {
    const quote = await getQuote(params);

    if (!quote.routePlan?.length) {
      throw new Error("No route found");
    }

    const swap = await getSwapTransaction(quote, params.userPublicKey);
    const tx = deserializeTransaction(swap.swapTransaction);
    tx.sign([params.keypair]);

    const signature = await connection.sendTransaction(tx, {
      skipPreflight: false,
      maxRetries: 3,
    });

    return { success: true, signature };
  } catch (error) {
    if (error.message.includes("insufficient")) {
      return { success: false, error: "Insufficient balance" };
    }
    if (error.message.includes("slippage")) {
      return { success: false, error: "Slippage exceeded" };
    }
    return { success: false, error: error.message };
  }
}
```

## Platform Fees

Collect platform fees on swaps:

```typescript
const quote = await fetch(`${API_BASE}/quote?${new URLSearchParams({

## Guidelines

1. **Use Trade API for most cases** - Unified endpoint handles both sync/async
2. **Always handle async orders** - Check `executionMode` and poll status
3. **Set appropriate slippage** - "auto" for convenience, custom for control
4. **Include priority fees** - Essential for reliable execution
5. **Handle errors gracefully** - Network issues, slippage, insufficient balance
6. **Monitor rate limits** - Use API key for production
7. **Test on devnet first** - DFlow supports Solana devnet
