IDL GENERATOR

Auto-generate Interface Description Language files from Solana programs

ℹ️ ABOUT IDL GENERATION

GENERATION

✓Automatic IDL extraction from programs

✓Instruction parsing & analysis

✓Account structure detection

✓Type definition extraction

✓Error code documentation

FEATURES

⚡Anchor program support

⚡Native program analysis

⚡Multiple output formats

⚡Instruction simulation

⚡Validation & verification

SECURITY

🔒Read-only program access

🔒No modification to programs

🔒Safe bytecode analysis

🔒Verified program data only

🔒Client-side processing

HOW IT WORKS:

1. Enter program address or upload bytecode
2. Select analysis depth and output format
3. Tool extracts program instructions & accounts
4. Generates comprehensive IDL definition
5. Download or copy generated IDL file

LIMITATIONS:

• Complex programs may need manual review
• Some instruction details may be incomplete
• Custom types might require adjustment
• Generated IDL should be validated before use

  "name": "my_program",
  "instructions": [
    {
      "name": "initialize",
      "accounts": [
        {
          "name": "user",
          "isMut": true,
          "isSigner": true
        }
      ],

Common Use Cases:

Development Integration

Generate IDL files for unknown or undocumented programs to enable type-safe client development with Anchor TypeScript.

Protocol Analysis

Reverse engineer program interfaces to understand instruction structures and account requirements for integration or research.

Documentation Generation

Create comprehensive documentation for existing programs including instruction details and account structures.

Testing & Validation

Generate test cases and validation logic based on program interfaces to ensure correct client implementation.

Known Limitations & Solutions:

Complex custom types may not be fully detected

Solution: Review and manually adjust type definitions in generated IDL

Some instruction variants might be missed

Solution: Cross-reference with program source or documentation

Error messages may be generic or incomplete

Solution: Supplement with program-specific error documentation

Obfuscated programs cannot be analyzed

Solution: Request IDL from program authors or use verified sources
