IValueFactory

The IValueFactory interface provides a standardized way to retrieve dynamic on-chain values at runtime within ComposableCoW’s conditional order system.

​
Key Function

function getValue(bytes calldata data) external view returns (bytes32 value);
This accepts implementation-specific configuration and returns a computed bytes32 value.

​
Primary Use Cases

  • Temporal data: Block timestamps and epoch calculations
  • Price information: Oracle prices and exchange rates
  • Dynamic parameters: Portfolio balances and collateralization ratios

​
Implementation Examples

​
CurrentBlockTimestampFactory

Returns block.timestamp as a bytes32 value.

​
BlockNumberFactory

Returns block.number as a bytes32 value.

​
ChainlinkPriceFactory

Fetches the latest oracle price from a Chainlink price feed.

​
BalanceFactory

Queries token balances for specific addresses.

​
DynamicStrikeFactory

Calculates market-adjusted strike prices based on current oracle data.

​
Critical Requirements

  • Factories should maintain view functions only and avoid state modifications
  • Validate external oracle data
  • Optimize for gas efficiency
