The Spark Orderbook Contract is a decentralized order book implemented on the Fuel blockchain, designed to facilitate secure and transparent trading.

The Orderbook framework consists of five components, which can be found in the root folder:

• spark-market: This Sway contract contains all the trading logic, including functionalities for opening, closing, and matching orders. It serves as the core of the trading operations, with corresponding tests included.
• spark-registry: This Sway contract allows for the registration of new markets, specifically for asset trading pairs. It acts as a registry that keeps track of all available markets, with tests included.
• spark-cli: Spark CLI tools for deploying and interacting with contracts. Detailed information is available in the README file within the subfolder.
• spark-market-sdk: A Rust library (SDK) for interacting with the SparkMarket contract. Additional details can be found in the README file within its subfolder.
• spark-registry-sdk: A Rust library (SDK) for interacting with the SparkRegistry contract. More information is available in the README file within its subfolder.

To build the project and run all tests, execute the following command:

forc build --release & cargo test --release

To run fuzz tests, use the following command:

cargo test --release -- --ignored fuzz --test-threads=$(nproc || sysctl -n hw.ncpu)

The liquidation mechanism, error codes, and all contract methods are open for community contributions. Your input is welcome to help improve and expand the Spark Orderbook Contract, making it a more robust and feature-rich platform.
