Switchboard Oracle Protocol - Complete Integration Guide

The definitive guide for integrating Switchboard - the fastest, most customizable, and only permissionless oracle protocol on Solana.

What is Switchboard?

Switchboard is a permissionless oracle protocol enabling developers to bring custom data on-chain with industry-leading performance:

• **Price Feeds** - Real-time asset pricing with pull-based efficiency
• **Oracle Quotes** - Sub-second latency without on-chain storage (90% cost reduction)
• **Surge** - WebSocket streaming with sub-100ms latency
• **VRF Randomness** - Cryptographically secure verifiable random functions
• **Prediction Markets** - Market-based forecasting data

Key Statistics

• Secures **$1B+** in on-chain volume
• Used by Kamino, Jito, MarginFi, Drift Protocol
• **2-5ms latency** with Surge pricing
• **90% cost reduction** vs traditional oracles

Core Principles

| Principle | Description | |-----------|-------------| | **Speed** | 2-5ms with Surge, 400ms standard - industry-leading for DeFi | | **Cost Efficiency** | Pull-based feeds eliminate constant streaming costs | | **Permissionless** | Deploy feeds instantly without approvals | | **Security** | TEE (Trusted Execution Environments) prevent data manipulation |

Integration Approaches

1. Oracle Quotes (Recommended)

Direct oracle-to-program data flow without on-chain storage:

• Sub-second latency
• 90% cost reduction
• No write locks (parallel reads)
• Stateless design

2. Traditional Feeds

Classic pull-based feed updates:

• Feed account maintenance
• Cranking operations
• Good for simple use cases

3. Surge (Real-Time)

WebSocket streaming for high-frequency applications:

• Sub-100ms latency
• Persistent connections
• Ideal for trading interfaces

Quick Start

Installation

# TypeScript SDK
npm install @switchboard-xyz/on-demand @switchboard-xyz/common

# Rust (Cargo.toml)
# switchboard-on-demand = "0.8.0"

Basic Setup

import { web3, AnchorProvider, Program } from "@coral-xyz/anchor";
import {
  PullFeed,
  CrossbarClient,
  ON_DEMAND_MAINNET_PID,
  ON_DEMAND_DEVNET_PID
} from "@switchboard-xyz/on-demand";

// Setup connection and provider
const connection = new web3.Connection("https://api.mainnet-beta.solana.com");
const wallet = useWallet(); // or Keypair
const provider = new AnchorProvider(connection, wallet);

// Load Switchboard program
const sbProgram = await Program.at(ON_DEMAND_MAINNET_PID, provider);

// Initialize Crossbar client for oracle communication
const crossbar = new CrossbarClient("https://crossbar.switchboard.xyz");

Price Feeds

Fetch and Update Feed

import { PullFeed, asV0Tx } from "@switchboard-xyz/on-demand";

// Create feed account reference
const feedPubkey = new web3.PublicKey("YOUR_FEED_PUBKEY");
const feedAccount = new PullFeed(sbProgram, feedPubkey);

// Fetch update instruction with oracle signatures
const { pullIx, responses, numSuccess, luts } = await feedAccount.fetchUpdateIx({
  crossbarClient: crossbar,
  chain: "solana",
  network: "mainnet", // or "devnet"
});

// Build and send transaction
const tx = await asV0Tx({
  connection,
  ixs: [pullIx],
  signers: [payer],
  computeUnitPrice: 200_000,
  computeUnitLimitMultiple: 1.3,
  lookupTables: luts,
});

const signature = await connection.sendTransaction(tx);
console.log("Feed updated:", signature);

Read Feed Value

// Get current feed value
const feedData = await feedAccount.loadData();
const value = feedData.value.toNumber();
const lastUpdated = feedData.lastUpdatedSlot;

console.log(`Price: ${value}, Last Updated: ${lastUpdated}`);

Oracle Quotes (Recommended)

Oracle Quotes provide the most efficient way to consume oracle data:

import { OracleQuote } from "@switchboard-xyz/on-demand";

// Feed hashes (64-char hex strings)
const feedHashes = [
  "0x...", // SOL/USD
  "0x...", // BTC/USD
];

// Derive canonical quote account
const queueKey = new web3.PublicKey("A43DyUGA7s8eXPxqEjJY6EBu1KKbNgfxF8h17VAHn13w");
const quotePubkey = OracleQuote.getCanonicalPubkey(queueKey, feedHashes);

// Fetch quote instruction
const sigVerifyIx = await queue.fetchQuoteIx(crossbar, feedHashes, {
  numSignatures: 1,
  variableOverrides: {},
});

Rust Integration (Oracle Quotes)

use anchor_lang::prelude::*;
use switchboard_on_demand::{default_queue, SwitchboardQuoteExt, SwitchboardQuote};

#[program]
pub mod my_program {
    use super::*;

    pub fn read_oracle_data(ctx: Context<ReadOracleData>) -> Result<()> {
        let feeds = &ctx.accounts.quote_account.feeds;
        let current_slot = ctx.accounts.sysvars.clock.slot;
        let quote_slot = ctx.accounts.quote_account.slot;

        // Check staleness
        let staleness = current_slot.saturating_sub(quote_slot);
        require!(staleness < 100, ErrorCode::StaleFeed);

        for feed in feeds.iter() {
            msg!("Feed {}: Value = {}", feed.hex_id(), feed.value());
        }

        Ok(())
    }
}

#[derive(Accounts)]
pub struct ReadOracleData<'info> {
    #[account(address = quote_account.canonical_key(&default_queue()))]
