## 📊 Project Status

| Category | Status | Completion |
|----------|--------|------------|
| **Development Tasks** | ✅ Complete | 112/112 (100%) |
| **MetaMask Integration** | ✅ Complete | 25/25 (100%) |
| **Deployment Automation** | ✅ Complete | All scripts ready |
| **Documentation** | ✅ Complete | 40+ documents |
| **Security Scanning** | ✅ Complete | 5 tools integrated |
| **Monitoring & Observability** | ✅ Complete | Full stack deployed |
| **Testing Infrastructure** | ✅ Complete | Multi-layer testing |
| **Governance Framework** | ✅ Complete | Full framework |
| **WETH9/WETH10 with CCIP** | ✅ Complete | Cross-chain ready |
| **OpenZeppelin Dependencies** | ✅ Hybrid Approach | OpenZeppelin v4.9.6 installed |

**Status**: ✅ Core implementation complete, with ongoing operator cleanup and deployment-hygiene work.

> **Note**: 30 deployment and integration tasks remain (operational procedures, external submissions). All code tasks are 100% complete. See [Next Steps](docs/operations/tasks/NEXT_STEPS_LIST.md) for deployment tasks.
> 
> **Dependency Status**: Hybrid approach implemented - OpenZeppelin v4.9.6 installed (compatible with Solidity 0.8.19). New WETH contracts (WETH10, CCIPWETH9Bridge, CCIPWETH10Bridge) are independent and don't require OpenZeppelin. Active OpenZeppelin-dependent contracts include CCIPSender, CCIPRouter, MultiSig, and Voting; the historical `CCIPRouterOptimized` source now lives under `archive/solidity/contracts/ccip/`. See [Hybrid Approach Implementation](docs/guides/HYBRID_APPROACH_IMPLEMENTATION.md) and [Dependencies Guide](docs/guides/DEPENDENCIES.md) for details.

## 🚀 Deployment Options

### Option 1: AKS Deployment (Recommended)

```bash
# Complete automated deployment
make deploy-all

# Or step by step
make deploy-infra      # Deploy Azure infrastructure
make deploy-k8s        # Deploy Kubernetes resources
make deploy-blockscout # Deploy Blockscout explorer
make deploy-contracts  # Deploy smart contracts
make deploy-dns        # Configure Cloudflare DNS
make verify           # Verify deployment
```

**Features**:
- ✅ Kubernetes orchestration
- ✅ Auto-scaling
- ✅ Service discovery
- ✅ Rolling updates
- ✅ High availability

### Option 2: VM/VMSS Deployment

```bash
# Deploy VM infrastructure
cd terraform
terraform apply -var-file=terraform.tfvars.vm -var="vm_deployment_enabled=true"

# VMs are automatically configured via cloud-init
```

**Features**:
- ✅ Virtual Machines or VM Scale Sets
- ✅ Docker Engine on VMs
