Experimental Technology
The Arkade Compiler is experimental technology in active development. All code and examples presented here are for exploration and proof of concept purposes only. Do not use in production environments.
Arkade Compiler
Arkade Compiler Official repository for the Arkade Script compiler
The Arkade Compiler transforms high-level Arkade Script contracts into optimized Bitcoin Taproot scripts. It handles the complexity of Bitcoin Script generation, allowing developers to focus on contract logic rather than low-level script details.
Basic Usage
This will compile your Arkade Script contract to a JSON file that can be used with Bitcoin Taproot libraries.
Compiler Architecture
The Arkade Compiler consists of several components:
Lexer : Tokenizes the source code
Parser : Builds an abstract syntax tree (AST)
Type Checker : Verifies type correctness
Optimizer : Optimizes the AST for efficient execution
Code Generator : Generates Bitcoin Script from the optimized AST
Compilation Process
The compilation process follows these steps:
Parse the Arkade Script source code
Analyze the contract structure and dependencies
For each function in the contract:
Generate the cooperative path (with server signature)
Generate the unilateral path (with timelock)
Optimize the generated scripts
Generate the Taproot output structure
Output the compiled contract in JSON format
Compiler Options
The Arkade Compiler supports several command-line options:
# Compile with optimization level 2 (more aggressive)
arkadec --opt-level=2 contract.ark
# Output assembly instead of bytecode
arkadec --output=asm contract.ark
# Generate debug information
arkadec --debug contract.ark
# Specify output file
arkadec --output-file=contract.json contract.ark
Compilation Artifacts
The compiler produces a JSON file containing:
Contract metadata (name, version, etc.)
Constructor parameters
Function definitions
Generated script for each function (both cooperative and unilateral paths)
Source map for debugging

"contractName" : "MyContract" ,

Script Optimization
The Arkade Compiler includes several optimization passes:
Constant folding : Evaluates constant expressions at compile time
Dead code elimination : Removes unreachable code
Stack optimization : Minimizes stack operations
Script size reduction : Compresses the generated script
These optimizations help reduce transaction fees and improve execution efficiency.
Debugging Support
The compiler provides debugging support through:
Source maps linking Bitcoin Script operations to Arkade Script source code
Detailed error messages with line and column information
Warnings for potential issues
Simulation mode for testing contract execution
The Arkade Compiler integrates with other development tools:
Contract Simulator : Test contract execution in various scenarios
Debugger : Step through contract execution to identify issues
Contract Explorer : Visualize contract state and execution paths
Future Directions
The Arkade Compiler roadmap includes:
Formal verification : Mathematical proof of contract correctness
Gas estimation : Predicting transaction fees before deployment
Cross-contract compilation : Supporting contract composition
Optimized library support : Pre-compiled common contract patterns
