+# 🚀 Local Contract Deployment & Validation Guide
+
+This document details the Soroban smart contract deployment validation script for NotifyChain (Issue #715).
+
+---
+
+## 1. Overview & Validation Rules
+
+The deployment utility `scripts/deploy-contract.sh` guarantees deterministic, safe deployments with the following rules:
+
+1. **Explicit Network Required**: Caller must specify `--network=local`, `--network=testnet`, or `--network=mainnet`. Defaulting implicitly is blocked to prevent accidental mainnet deployments.
+2. **Actionable Missing Config Errors**: If required RPC parameters or deployer secrets are absent, the script outputs actionable remediation commands.
+3. **Zero Secret Leakage**: `STELLAR_SECRET_KEY` and credentials are never printed to logs or standard output.
+4. **Contract Identification**: Output clearly identifies the deployed Contract ID (`C...`), WASM bytecode hash, target network, and timestamp.
+
+---
+
+## 2. Usage Examples
+
+### Validate Environment Prerequisites:
+```bash
+./scripts/deploy-contract.sh --network=local --validate-only
+```
+
+### Dry-run Simulation:
+```bash
+./scripts/deploy-contract.sh --network=testnet --dry-run
+```
+
+### Live Testnet Deployment:
+```bash
+export STELLAR_SECRET_KEY="S..."
+./scripts/deploy-contract.sh --network=testnet
+```
+
+---
+
+## 3. Automated Test Suite
+
+Run the deployment validation test suite:
+
+```bash
+./scripts/deploy-contract.test.sh
+```
