MultiversX WASM Debugging

Analyze compiled output.wasm files for size optimization, panic investigation, and source-level debugging. This skill helps troubleshoot deployment issues and runtime errors.

When to Use

• Contract deployment fails due to size limits
• Investigating panic/trap errors at runtime
• Optimizing WASM binary size
• Understanding what's in your compiled contract
• Mapping WASM errors back to Rust source code

1. Binary Size Analysis

Using Twiggy

Twiggy analyzes WASM binaries to identify what consumes space:
