+## Moving a Contract from Testnet to Mainnet
+
+This guide outlines the process for securely deploying Soroban smart contracts from testnet to mainnet using GitHub Actions and Github Attestation for source code validation.
+
+## Steps to Deploy
+
+### 1. Set Up Contract Source Validation
+
+- Configure your GitHub repository for automated source validation.
+- Create a workflow file `.github/workflows/release.yml` in your repository.
+
+Example workflow:
+
+```yaml
+name: Build and Release # arbitrary name
+on:
+ push:
+ tags:
+ - "v*" # triggered whenever a new tag (prefixed with "v") is pushed
+
+permissions: # required permissions
+ id-token: write
+ contents: write
+ attestations: write
+
+jobs:
+ release-contract-a:
+ uses: stellar-expert/soroban-build-workflow/.github/workflows/release.yml@main
+ with:
+ release_name: ${{ github.ref_name }} # git tag as unique release name
+ release_description: "Contract release" # text to attach to the release
+ relative_path: '["src/my-awesome-contract"]' # relative contract path
+ package: "my-awesome-contract" # package name to build
+ make_target: "build-dependencies" # make target to invoke
+ secrets: # authentication tokens will be automatically created by GitHub
+ release_token: ${{ secrets.GITHUB_TOKEN }} # don't modify this line
+```
+
+### 2. Compile and Validate Contract
+
+- Trigger the workflow by pushing a new tag (e.g., `v1.0`).
+- The workflow will:
+ - Compile the contract to WASM.
+ - Publish a GitHub release with build artifacts.
+ - Generate a GitHub attestation, linking the WASM to the source code.
+
+```bash
+ stellar contract build \
+ --meta name="Contract Name" \
+ --meta description="Descripton of the contract"
+ --meta source="https://api.github.com/repos//"
+```
+
+### 3. Deploy to Mainnet
+
+- Retrieve the compiled WASM from the GitHub release.
+- Deploy the WASM to the Stellar mainnet using the Soroban CLI:
+
+```bash
+ stellar contract deploy --source-acount --wasm --network mainnet
+```
+
+### 4. Verify Contract Authenticity
+
+Use the GitHub API to confirm the WASM's source: Retrieve attestation via: `https://api.github.com/repos///attestations/sha256:` Ensure the source code and commit hash match the deployed contract.
