Oracle Integration in Aiken

The oracle integration in Aiken repository demonstrates how to integrate oracles into Cardano smart contracts using the Aiken programming language. It includes an oracle datum module and will feature example implementations, such as a betting contract, to showcase practical applications of oracle data in Cardano dApps.

Note: Compatible with aiken v1.0.29-alpha+16fb02e

Project Structure

lib/: Houses the core oracle integration module.
- oracle_datum.ak: Contains the oracle datum definitions, functions, and associated tests.
aiken.toml: Project configuration file.
README.md: This file, providing project overview and instructions.

Oracle Datum Module

The oracle datum module in lib/oracle_datum.ak provides:

Definitions for oracle data structures
Functions for handling oracle data
Tests for the oracle datum functionality

All tests for the oracle datum are included directly in the oracle_datum.ak file, allowing for easy reference and maintenance alongside the implementation.

Building

To build the project, run:

aiken build

This will compile all Aiken modules and generate the necessary Plutus scripts.

Testing

Since tests are included in the oracle_datum.ak file, you can run them using:

aiken check

To run tests matching a specific string (e.g., “oracle”), use:

aiken check -m oracle

Usage

To use the oracle integration in your own project:

Copy the lib/oracle_datum.ak file to your project’s lib/ directory.
Import the oracle module in your validator:

use oracle_datum

validator {
  fn example(datum: Data, redeemer: Data, context: Data) -> Bool {
    // Use oracle functions here
    // e.g., oracle_datum.get_price(datum)
  }
}
