Documentation

n8n-nodes-solana

This is an n8n community package for Solana blockchain operations. It lets you sign transactions and extract wallet information using Solana secret keys in your n8n workflows.

Solana is a high-performance blockchain platform designed for decentralized applications and crypto-currencies.

n8n is a fair-code licensed workflow automation platform.

⚠️ Security Warning

IMPORTANT: This package requires access to your Solana private keys for signing operations. Please be aware of the following security considerations:

  • Never use this package in n8n Cloud or any untrusted environment - Any system running this package will have full access to your signing keys
  • Only use in self-hosted n8n instances that you fully control and trust
  • Store private keys securely using environment variables, never hardcode them
  • Use dedicated signing keys - Consider using keys specifically for automated workflows rather than your main wallet keys
  • Audit your workflows - Ensure only trusted parties have access to workflows using these nodes
  • Monitor key usage - Keep track of what transactions are being signed

Follow the installation guide in the n8n community nodes documentation.
