rug-check — Solana Token Safety

Read-only safety diligence for any Solana token mint. Never signs anything. It pairs with the ClawPump MCP trade/launch tools (swap_execute, launch_token_gasless, …) as the pre-flight that decides whether a token is safe to touch.

Two independent sources, cross-checked:

1. On-chain (authoritative): Solana JSON-RPC for mint/freeze authority and

real top-holder concentration — facts, not opinions.

1. RugCheck (heuristic): a community risk score + flagged risks.

Helper: scripts/rugcheck.py. Endpoint reference: references/api-endpoints.md.

When to Use

• Before any `swap_execute` into an unfamiliar token.
• A user pastes a mint and asks "is this safe / is it a rug / can I ape this?"
• Before launching or buying alongside an existing token.
• Vetting a token a tracked wallet/whale just bought.

Quick Check (do this first)

python3 ~/.hermes/skills/crypto/rug-check/scripts/rugcheck.py check <MINT>

This prints a consolidated verdict: authority status, top-10 concentration, RugCheck score, and a CLEAN / CAUTION / RUGGABLE line with the reasons.

Key Concepts

• Mint authority — if NOT revoked (non-null), the team can mint unlimited

new supply and dilute you. Revoked (null) is the safe state.

• Freeze authority — if NOT revoked, the team can freeze your tokens so

you can't sell. Revoked (null) is safe.

• LP locked vs burned — liquidity that's burned/locked can't be pulled

(the classic "rug"). Unlocked LP is a red flag.

• Top-holder concentration — a few wallets holding most of the supply can

dump on everyone. >30% top-10 is elevated, >60% is dangerous. (Some large holders are locked LP / CEX / vesting — verify owners before concluding.)

• RugCheck score — heuristic, not a guarantee. Use it as a signal, not a verdict.

Individual Commands

# RPC authority cross-check (mint can't be inflated / frozen?)
python3 scripts/rugcheck.py authority <MINT>
 
# Holder concentration from on-chain largest accounts
python3 scripts/rugcheck.py holders <MINT> --top 10
 
# RugCheck quick summary (+ risk flags) / full report
python3 scripts/rugcheck.py summary <MINT>
python3 scripts/rugcheck.py report  <MINT>

Raw curl equivalents (no key needed) are in references/api-endpoints.md.

Presenting Results

Lead with the verdict line, then the evidence:

⚠️ CAUTION — mint authority is still ACTIVE (supply can be inflated) and

the top 10 wallets hold 41%. RugCheck score 1,800.

Mint/freeze: mint ACTIVE 🔴 / freeze revoked ✅. I'd size small or skip.

Always show percentages and the score band. Never auto-execute a trade off a "clean" result — confirm with the user (and follow the ClawPump confirmation rules) before any swap_execute / launch.

Rate Limits & Keys

• RugCheck public endpoints are rate-limited (best-effort; brand-new tokens may

have no report yet — fall back to the on-chain authority/holder check).

• Solana RPC: defaults to the public api.mainnet-beta.solana.com. For heavier

use, set SOLANA_RPC_URL or HELIUS_API_KEY (free at dev.helius.xyz) — the script picks them up automatically.

Pitfalls

• A "clean" mint can still dump — LP unlocked, insider wallets, or social

manipulation aren't fully captured here. This is risk reduction, not a guarantee.

• getTokenLargestAccounts returns token accounts; a big one may be locked

LP, a CEX, or a vesting contract — note that rather than calling it a whale.

• RugCheck score is heuristic and can disagree with the on-chain facts — trust

the on-chain authority check over the score when they conflict.

• This is not financial advice and never a reason to skip user confirmation.

Notes for Hermes

• Use the terminal tool with python3/curl (not web_extract).
• HELIUS_API_KEY / SOLANA_RPC_URL flow from ~/.hermes/.env automatically.
• Read-only: this skill complements — never replaces — the ClawPump MCP

(mcp_clawpump_*) trade and launch tools.
