Get StartedIntroduction

Solduino

Solduino is an embedded-first SDK that brings core Solana capabilities to Arduino and ESP32 devices. It gives you the building blocks to connect to RPC endpoints, manage wallets, compose and sign transactions, and ship real device-to-chain workflows with familiar Arduino development patterns.

An MCP server is also available at https://mcp.solduino.com/api/mcp for AI-assisted development in Cursor, Claude Desktop, and other MCP clients. See MCP Server for setup and tool reference.

What You Can Build

  • Production-ready embedded wallets with on-device signing.
  • Reliable sensor-to-chain telemetry pipelines for IoT and DePIN use cases.
  • Custom instruction workflows for interacting with your own Solana programs.
  • End-to-end transaction flows, from payload construction to network submission.
  1. Start with Installation.
  2. Run the Quick Start.
  3. Move to Guides for real workflows.
  4. Use API Reference while implementing production code.
  5. Optional: connect the MCP Server for AI-assisted SDK lookup.
