# Deploying

> Guide to deploying ComposableCoW contracts using script-based or deterministic CREATE2 deployment.

# Deploying

## Core Deployment Methods

ComposableCoW offers two primary approaches:

1. **Script-Based Deployment**: Offers flexibility for testing but won't deploy to official addresses
2. **Deterministic CREATE2 Deployment**: Ensures identical addresses across all networks for production use

## Essential Setup

You'll need to configure environment variables including:

* RPC endpoints
* Private keys
* Settlement contract address (varies by network)

Foundry installation is required:

```bash theme={null}
curl -L https://foundry.paradigm.xyz | bash
foundryup
```

## Deployment Options

### Full Production Stack

Deploys multiple components in one transaction:

* ExtensibleFallbackHandler
* ComposableCoW
* Five order types (TWAP, GoodAfterTime, PerpetualStableSwap, TradeAboveThreshold, StopLoss)
* Utilities

### Individual Contract Deployment

Separate scripts for ComposableCoW alone or order types specifically.

## Deterministic CREATE2 Benefits

* Consistent addresses across all networks
* Simplified integration and documentation
* Predictable contract locations
* Enhanced user trust

## Local Testing

For integration testing, Anvil provides a local environment with the full CoW Protocol stack deployment capability, including a test Safe contract.

```bash theme={null}
anvil --fork-url $ETH_RPC_URL
```

## Post-Deployment Tasks

1. Verify deployments using `cast code`
2. Update the `networks.json` registry
3. Leverage the `broadcast/` directory artifacts containing deployment metadata and ABIs
