Infrastructure & Documentation

• ✅ Updated DockerfileSuperchain: Base image from node16 → node22
• ✅ Updated CONTRIBUTING.md: Node.js version references updated

Testing

• Verify Lambda functions deploy successfully with Node.js 22 runtime
• Verify build scripts work correctly with Node.js 22
• Verify CI/CD pipelines pass with Node.js 22
• Test local development setup with Node.js 22

Breaking Changes

⚠️ Minimum Node.js version requirement is now 22.0.0

Developers and CI/CD environments must have Node.js 22 installed to work with this codebase.

Migration Notes

1. Update local Node.js version:

   nvm install 22
   nvm use 22

2. Reinstall dependencies:

   yarn install

3. Rebuild the project:

   yarn build:all
