Solana Program Account Scanner

Overview

This script scans and extracts account information for Solana programs based on their Interface Definition Language (IDL) files. It uses the @coral-xyz/anchor and @solana/web3.js libraries to interact with the Solana blockchain, identify different types of accounts, and decode account data.

Features

• Loads IDL files from target/idl/.
• Scans all accounts associated with detected programs.
• Identifies account types: Wallets, PDAs, Data Accounts, and Programs.
• Decodes account data using the BorshAccountsCoder.
• Saves all extracted information to accounts.json.
• Display it

Prerequisites

Ensure you have the following installed:

• Node.js (>=16.x recommended)
• Anchor framework (for building Solana programs)
• Solana CLI (for interacting with the blockchain)

Installation

npm install anchorx-ray

Configuration

If your test don't use the same rpc url, you can change in the .env file:

RPC_URL=<YOUR_RPC>

If no RPC URL is provided, the script defaults to http://127.0.0.1:8899 (local Solana test validator).

Usage

Run the script in your Anchor project:

npx anchorx-ray

This will:

1. Load all IDL files from target/idl/.
2. Fetch programs owned by the accounts from the RPC.
3. Identify and categorize these accounts using IDL and some other computations.
4. Save the results in accounts.json.
5. Open a visualization at http://localhost:3000/ in the browser.

Account Type Identification

The script categorizes accounts as:

• Program Account: The executable program itself.
• Wallet: A system account owned by the Solana System Program. (normally it will not happen for the moment since only accounts owned by the program are taken from the RPC)
• PDA (Program Derived Address): A non-executable program-owned address.
• Data Account: A regular program-owned account storing data.
• Other: Any account that doesn’t fit the above categories.

Output Format

The output is saved in accounts.json and contains details like:

[
  {
    "name": "example_program",
    "address": "ABC123...",
    "owner": "11111111111111111111111111111111",
    "lamports": 1000000,
    "executable": true,
    "dataSize": 0,
    "accountType": "Program",
    "decodedData": null
  }
]

And it will open a diagram showing all accounts used in the tests (program + accounts owned by the program)

Troubleshooting

• No IDL files found: Ensure you have built your Anchor program using anchor build.
• Failed to fetch accounts: Check your RPC URL and network connection.
• Only one program is shown in the diagram: Ensure you have run tests.

For developers

If you want to update a part of the script,

1. Clone the repo

gh repo clone crytic/anchorx-ray

2. Install dependencies

npm install

3. Do your modifications
4. Then

npm run build
