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:

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.

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
