+# 📋 Contract Deployment Artifact Manifest Specification
+
+This document defines the deployment manifest schema for NotifyChain's Soroban smart contracts across local, testnet, and production environments (Issue #716).
+
+---
+
+## 1. Motivation & Purpose
+
+To ensure reproducible testing and seamless frontend/listener synchronization, contract deployments produce a deterministic JSON manifest (`deployments/deployment-manifest.json`) recording contract IDs, bytecode hashes, network RPC endpoints, and git commits.
+
+---
+
+## 2. Manifest Schema
+
+```json
+{
+  "schema_version": "1.0.0",
+  "contract": {
+    "id": "<SOROBAN_CONTRACT_ID_C...>",
+    "name": "notify-chain-events",
+    "wasm_hash": "<SHA256_HEX_WASM_HASH>"
+  },
+  "network": {
+    "name": "testnet",
+    "rpc_url": "https://soroban-testnet.stellar.org",
+    "passphrase": "Test SDF Network ; September 2015"
+  },
+  "deployment": {
+    "deployer_public_key": "<STELLAR_PUBLIC_KEY_G...>",
+    "timestamp": "2026-08-29T12:00:00.000Z",
+    "git_commit": "<GIT_COMMIT_SHA>"
+  }
+}
+```
+
+---
+
+## 3. Security Invariants
+
+* **No Secret Keys**: Manifest generation strictly forbids and rejects Stellar secret keys (`S...`). Only public identifiers (`C...`, `G...`) and hashes are included.
+* **Non-destructive Overwrites**: Manifests are committed per-environment to allow automated integration testing without manual parameter copying.
+
+---
+
+## 4. Usage
+
+Generate deployment manifest from environment variables:
+
+```bash
+node scripts/generate-deployment-manifest.js
+```
