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. 
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
