IConditionalOrder
The IConditionalOrder interface establishes verification logic for conditional orders in ComposableCoW, with an extension (IConditionalOrderGenerator) supporting on-chain order generation.
Key Interfaces
IConditionalOrder
Provides the base verify() function that validates whether a discrete order meets conditional criteria. The function must revert if conditions aren’t satisfied.
IConditionalOrderGenerator
Extends the base interface by adding:
getTradeableOrder() - Generates orders ready for submission to the CoW Protocol API- ERC-165 support
Essential Components
ConditionalOrderParams
Uniquely identifies orders through three elements:
| Field | Description |
|---|
handler | Contract implementing the conditional logic |
salt | Unique identifier value |
staticInput | ABI-encoded order parameters |
verify()
Accepts:
- Owner address
- Sender address
- Order hash
- Domain separator
- Context
- Static input
- Off-chain input
- The order itself
getTradeableOrder()
Generates tradeable orders by processing similar parameters but excluding the order data field.
Error Handling Strategy
| Error | Description |
|---|
OrderNotValid | Standard condition failure |
PollTryNextBlock | Retry in the next block |
PollTryAtBlock / PollTryAtEpoch | Schedule specific retry times |
PollNever | Permanent discontinuation |
Implementation Pattern
The BaseConditionalOrder abstract contract demonstrates standard verification by comparing generated order hashes. Concrete implementations like StopLoss show oracle-based price checking with timestamp validation and strike price evaluation.Last modified on March 4, 2026
