Scans TON (The Open Network) smart contracts for 3 critical vulnerabilities including integer-as-boolean misuse, fake Jetton contracts, and forward TON without gas checks. Use when auditing FunC contracts.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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
;; 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

How to install
mdr add trailofbits/skills/ton-vulnerability-scanner@sha256:e02e01228f892ed0The line at the top of this page pins the label git:20260831.6feac67, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
