WebAssembly Validator

Visualizing module validation in WebAssembly

Validation Process

1. Parse Module

Parses the binary format and checks for valid section ordering

2. Type Checking

Validates function signatures, parameter types, and return values

3. Structural Validation

Checks section boundaries, instruction operands, and operand counts

4. Control Flow

Ensures valid control flow graphs and block structures

5. Final Verification

Confirms the overall module structure meets spec requirements
