Switchboard

Under active development

Switchboard is under active development. APIs, schemas, and on-chain layouts may change. Production use at your own risk. Issues + PRs welcome — see the GitHub repo.

Unified Cross-Chain State Synchronization Platform

Switchboard enables seamless cross-chain state synchronization, allowing developers to deploy once and sync everywhere. By leveraging Solana's performance and sub-second finality, Switchboard provides real-time verification across all supported chains with sub-400ms coordination latency.

Key Features

  • 🚀 Sub-400ms Latency

    Real-time cross-chain coordination using Solana as the high-performance coordination layer

  • ⛓ 50+ Chain Support

    All major EVM and non-EVM networks including Ethereum, Polygon, Arbitrum, Solana, NEAR, Cosmos, Sui, and more

  • 🏗 90% Code Reuse

    Write once, deploy everywhere with unified contract patterns across chains

  • 💾 Flexible Database

    Choose between MongoDB or PostgreSQL based on your infrastructure needs

Quick Start

Get started with Switchboard in under 5 minutes:

# Install the CLI globally
npm install -g @switchboard/cli

# Verify installation
switchboard --version

# Install the SDK for programmatic use
npm install @switchboard/sdk

Create Your First Project

# Initialize a new project (development mode uses testnets)
switchboard init my-first-dapp --dev-mode

cd my-first-dapp

# Deploy to multiple testnets
switchboard deploy --dev-mode

# Monitor deployment status
switchboard status --watch
