solana-rug 0.1.0

On-chain rug-pull detection for Solana tokens — Safety Score 0-100, zero paid APIs required.

Solana Rug Guard

13-factor on-chain rug-pull detection for Solana tokens and wallets. No paid APIs. No registration. Just a Python script and a Hermes skill.

Run it as a one-shot CLI against any mint or wallet. Or install it as a Hermes Agent skill and ask in natural language: "Hey Hermes, is this token safe?" Every check is deterministic — the same input always produces the same score, with a full breakdown of why.

Install & Get Started

Prerequisites

• Python 3.11+
• Hermes Agent (optional — the CLI works standalone)
• No API keys. The tool uses public Solana RPCs and the free DexScreener API.

Always install from a trusted source. Official packages are published to PyPI and GitHub Releases. The source is a single auditable Python file — no compiled binaries, no opaque dependencies. You can verify the checksums on the GitHub Releases page and compare against the source in this repo.

Option A: Install as a Hermes Skill (recommended)

# From the Hermes Agent repo:
hermes skills install official/blockchain/solana-rug

# Or from a local checkout:
cd optional-skills/blockchain/solana-rug/
hermes skills install ./SKILL.md

Then ask in natural language:

"Is token DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 safe?"
"Rug-check F4J5LKyEQraMem8nspPAzwHXaaKMMDsxyt7GUK94pump"
"Scan wallet 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM for risky tokens"

Option B: Run the CLI Standalone

# Single file — no install needed (from GitHub Releases)
curl -OL https://github.com/rugpullnet/solana-rug/releases/latest/download/rugguard.py
python3 rugguard.py token DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 --md

# Or clone the repo
git clone https://github.com/rugpullnet/solana-rug.git
cd solana-rug
python3 scripts/rugguard.py --help

# Or pip install from PyPI (trusted source)
pip install solana-rug
solana-rug token DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263

Verify It Works

python3 rugguard.py token DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 --json

Expected: BONK returns safety_score: 100, zero warnings, market data showing $682k liquidity on Meteora.

How to Use

Token Analysis

# JSON output (default) — pipe through jq
python3 rugguard.py token <MINT_ADDRESS>

# Human-readable Markdown report
python3 rugguard.py token <MINT_ADDRESS> --md

# Full example
python3 rugguard.py token DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 --md

JSON output includes a market_data block with DexScreener enrichment:

{
  "safety_score": 100,
  "risk_level": "LOW",
  "flags": {
    "mint_authority_active": false,
    "freeze_authority_active": false,
    "sniper_detected": false,
    "suspicious_name": false,
    "sub_penny_price": false,
    "deployer_can_crash_price": false
  },
  "market_data": {
    "dex": "meteora",
    "liquidity_usd": 682156.92,
    "volume_24h": 936.68,
    "price_usd": 0.000004892,
    "price_change_24h": -2.92,
    "txns_24h": 212
  }
}

Wallet Scan

python3 rugguard.py wallet <ADDRESS>

Scans all SPL tokens held by a wallet. For each token with meaningful balance, checks mint authority. Returns a prioritized list of risky tokens ordered by safety score (lowest first).

Environment

Variable	Default	Description
SOLANA_RPC_URL	https://api.mainnet-beta.solana.com	Override RPC endpoint. Set to a private node (Helius, QuickNode) for production reliability.

The 13 Risk Factors

Each factor contributes zero or more points to the total risk score. Higher total risk = lower safety score.

#	Factor	Max	What It Catches	Data Source
1	Mint Authority	15	Dev can print unlimited new tokens	RPC
2	Freeze Authority	5	Dev can freeze accounts	RPC
3	LP Locked/Burned	15	LP tokens can be pulled, no pool exists	RPC + DexScreener
4	Liquidity Size	5	Pool under $20k → high price impact	DexScreener
5	Holder Concentration	10	Top 10 wallets own >50% of supply	RPC + DexScreener
6	Dev Risk	5	Dev holds >15% of supply	RPC
7	Token Age	5	Under 7 days old → statistically riskier	DexScreener
8	Mint History	5	Dev minted more tokens after launch	RPC
9	Honeypot	10	Sell simulation fails	Jupiter API
10	Sniper Bots	10	Bots bought within first 20 seconds	RPC sig analysis
11	Suspicious Name	5	Name contains "rug", "scam", "ponzi", etc.	On-chain + DexScreener
12	Sub-Penny Price	5	Price < $0.0001 on a young or thin token	DexScreener
13	Deployer Dump Risk	5	Dev could crash price by selling	DexScreener + RPC

How Risks Are Scored

Each check is independent and deterministic. The total risk sum has no upper cap — a token with every flag maxed out scores 0/100. The 13 factors are split across:

• 3 on-chain structural checks (mint authority, freeze authority, LP locked/burned) — the classic rug vectors
• 4 market-health checks (liquidity size, holder concentration, age, mint history) — sustainability signals
• 3 behavioral checks (honeypot, snipers, name stigma) — adversarial pattern detection
• 3 position checks (dev risk, sub-penny price, deployer dump risk) — who holds what and what that means

Score bands:

Score	Risk	Meaning
80-100	LOW	On-chain mechanics clean. Standard DeFi risks only.
50-79	MEDIUM	Some risk factors present. Review flagged warnings.
20-49	HIGH	Multiple red flags. Likely a risky token.
0-19	CRITICAL	Strong evidence of malicious setup.

Data Sources (in order of preference)

1. Solana public RPC — Mint accounts, token holders, signatures, program accounts. Retries across 4 public endpoints with round-robin fallback.
2. DexScreener API — Real pool data when getProgramAccounts is rate-limited. Provides price, liquidity, volume, pair info, and creation time.
3. Jupiter quote API — Optional honeypot check. Simulates a buy/sell to detect trade restrictions.

All calls are cached in-memory with a 5-minute TTL to avoid redundant network requests.
