Quickstart

​
Key Setup Requirements

ComposableCoW requires two critical Safe configurations:
  1. Fallback Handler: Install ExtensibleFallbackHandler (address: 0x2f55e8b20D0B9FEFA187AA7d00B6Cbe563605bF5) to enable EIP-1271 signature verification.
  2. Domain Verifier: Register ComposableCoW (address: 0xfdaFc9d1902f4e0b84f65F49f244b32b31013b74) as the signature verifier for CoW Protocol’s domain separator.

Creating a TWAP Order

The following demonstrates a 30-day TWAP strategy where Alice sells 12 million DAI for WETH in equal daily installments. Key parameters include:
  • partSellAmount: Individual trade size (400,000 DAI per day)
  • minPartLimit: Minimum per-trade output (250 WETH)
  • t: Time interval between executions (86,400 seconds = 1 day)
  • n: Total number of parts (30)
  • span: Execution window flexibility within each interval

​
Essential Steps

  1. Approve token spending via GPv2VaultRelayer
  2. Create ConditionalOrderParams with unique handler/salt/staticInput combinations
  3. Dispatch orders to watchtowers monitoring for trade conditions

​
Advanced Features

The span parameter restricts execution to specific time windows (e.g., business hours only), while the platform also supports Stop Loss orders triggered by price oracle thresholds.
