Use this skill

Your agent runs on

Adds every file the skill has, pinned so you can update it. No account needed.

pip install "decimalai>=0.15"
decimalai skills add trailofbits-ton-vulnerability-scanner
claude --plugin-dir "$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.agents"

The same install from Python, for a notebook or a setup script.

Install

pip install "decimalai>=0.15"

Add the skill

from decimalai import skillpkg

# Writes .agents/skills and .decimal/skills.toml. Safe to run twice.
result = skillpkg.add("trailofbits-ton-vulnerability-scanner")
if result.exit_code:
    raise SystemExit(result.problems)

print("Added. Start Claude Code with the command below.")

Start Claude Code with it

claude --plugin-dir "$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.agents"

Type these in a Claude Code session. No account or API key. It writes the skill and any files it bundles, and asks first when its safety rating isn't Passed.

Add the DecimalAI plugin, once

/plugin marketplace add decimal-labs/decimalai-claude-plugins
/plugin install decimalai@decimalai

Install this skill

/decimalai:install trailofbits-ton-vulnerability-scanner

The plugin needs python3 and curl on your machine.

No Python or account. Claude Code picks it up in its next session.

Save it into your project

curl -fsSL --create-dirs -o .claude/skills/trailofbits-ton-vulnerability-scanner/SKILL.md https://app.decimal.ai/s/trailofbits-ton-vulnerability-scanner/SKILL.md

Copy SKILL.md

Save it in your project, as

TON Vulnerability Scanner

1. Purpose

Systematically scan TON blockchain smart contracts written in FunC for platform-specific security vulnerabilities related to boolean logic, Jetton token handling, and gas management. This skill encodes 3 critical vulnerability patterns unique to TON's architecture.

2. When to Use This Skill

Auditing TON smart contracts (FunC language)
Reviewing Jetton token implementations
Validating token transfer notification handlers
Pre-launch security assessment of TON dApps
Reviewing gas forwarding logic
Assessing boolean condition handling

3. Platform Detection

File Extensions & Indicators

FunC files: .fc, .func

Language/Framework Markers

;; FunC contract indicators
#include "imports/stdlib.fc";

() recv_internal(int my_balance, int msg_value, cell in_msg_full, slice in_msg_body) impure {
    ;; Contract logic
}

() recv_external(slice in_msg) impure {
    ;; External message handler
}

;; Common patterns
send_raw_message()
load_uint(), load_msg_addr(), load_coins()
begin_cell(), end_cell(), store_*()
transfer_notification operation
op::transfer, op::transfer_notification
.store_uint().store_slice().store_coins()

Project Structure

contracts/*.fc - FunC contract source
wrappers/*.ts - TypeScript wrappers
tests/*.spec.ts - Contract tests
ton.config.ts or wasm.config.ts - TON project config

Tool Support

TON Blueprint: Development framework for TON
toncli: CLI tool for TON contracts
ton-compiler: FunC compiler
Manual review primarily (limited automated tools)

4. How This Skill Works

When invoked, I will:

Search your codebase for FunC/Tact contracts
Analyze each contract for the 3 vulnerability patterns
Report findings with file references and severity
Provide fixes for each identified issue
Check replay protection and sender validation

5. Example Output

When vulnerabilities are found, you'll get a report like this:

=== TON VULNERABILITY SCAN RESULTS ===

Project: my-ton-contract
Files Scanned: 3 (.fc, .tact)
Vulnerabilities Found: 2

---

[CRITICAL] Missing Replay Protection
File: contracts/wallet.fc:45
Pattern: No sequence number or nonce validation


---

## 5. Vulnerability Patterns (3 Patterns)

I check for 3 critical vulnerability patterns unique to TON. For detailed detection patterns, code examples, mitigations, and testing strategies, see [VULNERABILITY_PATTERNS.md](resources/VULNERABILITY_PATTERNS.md).

### Pattern Summary:

1. **Missing Sender Check** ⚠️ CRITICAL - No sender validation on privileged operations
2. **Integer Overflow** ⚠️ CRITICAL - Unchecked arithmetic in FunC
3. **Improper Gas Handling** ⚠️ HIGH - Insufficient gas reservations

For complete vulnerability patterns with code examples, see [VULNERABILITY_PATTERNS.md](resources/VULNERABILITY_PATTERNS.md).
## 5. Scanning Workflow

### Step 1: Platform Identification
1. Verify FunC language (`.fc` or `.func` files)
2. Check for TON Blueprint or toncli project structure
3. Locate contract source files
4. Identify Jetton-related contracts

### Step 2: Boolean Logic Review
```bash
# Find boolean-like variables
rg "int.*is_|int.*has_|int.*flag|int.*enabled" contracts/

# Check for positive integers used as booleans
rg "= 1;|return 1;" contracts/ | grep -E "is_|has_|flag|enabled|valid"

# Look for NOT operations on boolean-like values
rg "~.*\(|~ " contracts/

For each boolean:

Uses -1 for true, 0 for false
NOT using 1 or other positive integers
Logic operations work correctly

Step 3: Jetton Handler Analysis

# Find transfer_notification handlers
rg "transfer_notification|op::transfer_notification" contracts/

For each Jetton handler:

Validates sender address
Sender checked against stored Jetton wallet address
Cannot trust forward_payload without sender validation
Has admin function to set Jetton wallet address

Step 4: Gas/Forward Amount Review

# Find forward amount usage
rg "forward_ton_amount|forward_amount" contracts/
rg "load_coins\(\)" contracts/

# Find send_raw_message calls
rg "send_raw_message" contracts/

For each outgoing message:

Forward amounts are fixed/bounded
OR user-provided amounts validated against msg_value
Cannot drain contract balance
Appropriate send_raw_message flags used

Step 5: Manual Review

TON contracts require thorough manual review:

Boolean logic with ~, &, | operators
Message parsing and validation
Gas economics and fee calculations
Storage operations and data serialization

6. Reporting Format

Finding Template

## [CRITICAL] Fake Jetton Contract - Missing Sender Validation

**Location**: `contracts/staking.fc:85-95` (recv_internal, transfer_notification handler)

**Description**:
The `transfer_notification` operation handler does not validate that the sender is the expected Jetton wallet contract. Any attacker can send a fake `transfer_notification` message claiming to have transferred tokens, crediting themselves without actually depositing any Jettons.

**Vulnerable Code**:
```func
// staking.fc, line 85
if (op == op::transfer_notification) {
    int jetton_amount = in_msg_body~load_coins();
    slice from_user = in_msg_body~load_msg_addr();

    ;; WRONG: No validation of sender_address!
    ;; Attacker can claim any jetton_amount

    credit_user(from_user, jetton_amount);
}

Attack Scenario:

Attacker deploys malicious contract
Malicious contract sends transfer_notification message to staking contract
Message claims attacker transferred 1,000,000 Jettons
Staking contract credits attacker without checking sender
Attacker can now withdraw from contract or gain benefits without depositing

Proof of Concept:

// Attacker sends fake transfer_notification
const attackerContract = await blockchain.treasury("attacker");

await stakingContract.sendInternalMessage(attackerContract.getSender(), {
  op: OP_CODES.TRANSFER_NOTIFICATION,
  jettonAmount: toNano("1000000"), // Fake amount
  fromUser: attackerContract.address,
});

// Attacker successfully credited without sending real Jettons
const balance = await stakingContract.getUserBalance(attackerContract.address);
expect(balance).toEqual(toNano("1000000")); // Attack succeeded

Recommendation: Store expected Jetton wallet address and validate sender:

global slice jetton_wallet_address;

() recv_internal(...) impure {
    load_data();  ;; Load jetton_wallet_address from storage

    slice cs = in_msg_full.begin_parse();
    int flags = cs~load_uint(4);
    slice sender_address = cs~load_msg_addr();

    int op = in_msg_body~load_uint(32);

    if (op == op::transfer_notification) {
        ;; CRITICAL: Validate sender
        throw_unless(error::wrong_jetton_wallet,
            equal_slices(sender_address, jetton_wallet_address));

        int jetton_amount = in_msg_body~load_coins();
        slice from_user = in_msg_body~load_msg_addr();

        ;; Safe to credit user
        credit_user(from_user, jetton_amount);
    }
}

## 7. Priority Guidelines

### Critical (Immediate Fix Required)
- Fake Jetton contract (unauthorized minting/crediting)

### High (Fix Before Launch)
- Integer as boolean (logic errors, broken conditions)
- Forward TON without gas check (balance drainage)

---

## 8. Testing Recommendations

### Unit Tests
```typescript
import { Blockchain } from "@ton/sandbox";
import { toNano } from "ton-core";

describe("Security tests", () => {
  let blockchain: Blockchain;
  let contract: Contract;

  beforeEach(async () => {
    blockchain = await Blockchain.create();
    contract = blockchain.openContract(await Contract.fromInit());
  });

  it("should use correct boolean values", async () => {
    // Test that TRUE = -1, FALSE = 0
    const result = await contract.getFlag();
    expect(result).toEqual(-1n); // True
    expect(result).not.toEqual(1n); // Not 1!
  });

  it("should reject fake jetton transfer", async () => {
    const attacker = await blockchain.treasury("attacker");

    const result = await contract.send(
      attacker.getSender(),
      { value: toNano("0.05") },
      {
        $$type: "TransferNotification",
        query_id: 0n,
        amount: toNano("1000"),
        from: attacker.address,
      }
    );

    expect(result.transactions).toHaveTransaction({
      success: false, // Should reject
    });
  });

  it("should validate gas for forward amount", async () => {
    const result = await contract.send(
      user.getSender(),
      { value: toNano("0.01") }, // Insufficient gas
      {
        $$type: "Transfer",
        to: recipient.address,
        forward_ton_amount: toNano("1"), // Trying to forward 1 TON
      }
    );

    expect(result.transactions).toHaveTransaction({
      success: false,
    });
  });
});

Integration Tests

// Test with real Jetton wallet
it("should accept transfer from real jetton wallet", async () => {
  // Deploy actual Jetton minter and wallet
  const jettonMinter = await blockchain.openContract(JettonMinter.create());
  const userJettonWallet = await jettonMinter.getWalletAddress(user.address);

  // Set jetton wallet in contract
  await contract.setJettonWallet(userJettonWallet);

  // Real transfer from Jetton wallet
  const result = await userJettonWallet.sendTransfer(
    user.getSender(),
    contract.address,
    toNano("100"),
    {}
  );

  expect(result.transactions).toHaveTransaction({
    to: contract.address,
    success: true,
  });
});

10. Quick Reference Checklist

Before completing TON contract audit:

Boolean Logic (HIGH):

All boolean values use -1 (true) and 0 (false)
NO positive integers (1, 2, etc.) used as booleans
Functions returning booleans return -1 for true
Boolean logic with ~, &, | uses correct values
Tests verify boolean operations work correctly

Jetton Security (CRITICAL):

transfer_notification handler validates sender address
Sender checked against stored Jetton wallet address
Jetton wallet address stored during initialization
Admin function to set/update Jetton wallet
Cannot trust forward_payload without sender validation
Tests with fake Jetton contracts verify rejection

Gas & Forward Amounts (HIGH):

Forward TON amounts are fixed/bounded
OR user-provided amounts validated: msg_value >= tx_fee + forward_amount
Contract balance protected from drainage
Appropriate send_raw_message flags used
Tests verify cannot drain contract with excessive forward amounts

Testing:

Unit tests for all three vulnerability types
Integration tests with real Jetton contracts
Gas cost analysis for all operations
Testnet deployment before mainnet

When it activates

Automatically, when a task matches. Use when auditing FunC contracts.
