Solana Squads Upgrade

Automate Solana program upgrades through Squads v4 multisig using the squads-program-action GitHub Action. Covers configuration, transaction building, and the full upgrade lifecycle from CI to on-chain execution.

When to Use

• Setting up CI/CD for Solana program deployments with multisig governance
• Creating GitHub Actions workflows that submit upgrade proposals to Squads
• Configuring Anchor IDL or program-metadata updates alongside program upgrades
• Debugging failed Squads upgrade proposals
• Understanding the instruction flow: buffer -> multisig proposal -> approval -> execution

Architecture Overview

Creates a Squads vault transaction (multisig proposal), not a direct on-chain upgrade.
