PR Title

ci: automate Soroban contract deployment to Stellar Testnet on merge to main

Summary

This PR introduces an automated GitHub Actions deployment pipeline that deploys all Soroban contracts to the Stellar Testnet whenever changes are merged into the main branch. Deployments only occur after all tests and integration checks pass, ensuring only validated contract code reaches the testnet.

The workflow securely uses GitHub Secrets for deployment credentials, publishes deployed contract IDs as workflow artifacts, and includes a deployment summary for easy reference.

Changes Made

CI/CD Workflow

• Added GitHub Actions workflow to automatically deploy contracts after successful merges to main.

• Configured deployment to run only after:

  • Rust unit tests pass (cargo test)
  • Local Stellar sandbox integration tests complete successfully

• Prevents deployment if any validation step fails.

Automated Testnet Deployment

• Deploys all Soroban contracts to the Stellar Testnet.
• Uses the configured deployer account stored securely as a GitHub Secret.
• Eliminates manual deployment steps after successful merges.

Deployment Artifacts

• Saves deployed contract IDs as GitHub Actions artifacts.

• Generates a workflow summary containing:

  • Contract names
  • Testnet contract IDs
  • Deployment status
  • Deployment timestamp

Security

• Deployment credentials are loaded from GitHub Secrets.
• No private keys or sensitive credentials are stored in the repository or workflow logs.

Documentation

• Updated deployment documentation with:

  • CI deployment flow
  • Required GitHub Secrets
  • Deployment prerequisites
  • How to retrieve deployed contract IDs from workflow artifacts

Files Modified

• .github/workflows/testnet-deploy.yml
• Deployment scripts (if applicable)
• docs/ deployment documentation
• Related CI configuration files

Acceptance Criteria

• ✅ Rust implementation completed.
• ✅ cargo test passes successfully.
• ✅ Local Stellar sandbox integration tests pass.
• ✅ Contracts automatically deploy to Stellar Testnet after merges to main.
• ✅ Contract IDs are uploaded as CI artifacts.
• ✅ Workflow summary displays deployed contract IDs.
• ✅ Deployment uses GitHub Secrets for secure key management.
• ✅ Documentation updated.
