How to spot a
KRC-20 rug pull

In a launch wave, a fair launch and a rug look identical for the first few minutes — same countdown, same hype. The difference is in the on-chain numbers. Here are the 5 signals that separate them — and the free tool that reads all 5 for you.

The 30-second version

A rug hides in plain sight

On Kaspa, KRC-20 tokens launch through a public fair mint: the supply opens and anyone can mint until it fills. That transparency is the good news — every wallet, every balance and the deployer's own stake are public on-chain data you can read before you spend a single KAS.

A rug pull is simply a launch where the insiders quietly hold most of the supply — through a pre-mint, a heavy deployer balance, or a couple of coordinated wallets minting the bulk of it — and then dump on everyone who bought the hype. The signals are always there; the trick is knowing which five to read, and reading them before the mint, not after.

Below is the exact checklist. It's the same on-chain model our free Fair-Launch Radar runs on every live launch to hand you an A–F fairness grade in one glance — so you don't have to compute it by hand mid-mint.

The checklist

5 on-chain signals of a rug

Read these on any live KRC-20 launch from its public Kasplex data. Any one red flag is a warning; two or more is a walk-away.

1

Pre-mint — did insiders reserve supply first?

Pre-mint is supply handed to the deployer before the public mint opens. A true fair launch is zero pre-mint — everyone starts from the same line. Any pre-mint means the team already holds a stake you had no chance to earn, and can sell it into your buy.

🟢 0% — fair 🟡 under 5% — caution 🔴 5%+ — red flag, and worse the higher it goes
2

Top-wallet concentration — can one wallet crash it?

Look at the largest single holder's share of minted supply. If one wallet holds a huge slice, that wallet alone can dump and collapse the price at any moment. Early in a mint a little concentration is normal; a launch that stays concentrated as it fills is the danger.

🟢 under 10% — healthy 🟡 10–20% — watch 🔴 30–50%+ — heavily concentrated
3

Deployer balance — how much does the team itself hold?

Separate from pre-mint, check how much the deploying wallet is holding right now. A deployer sitting on a big chunk of supply is the most direct rug risk there is — they control the token and the stack that can dump it.

🟢 light / near-zero 🟡 5–15% 🔴 15–30%+ of supply
4

Holder spread — is anyone actually here?

Count the distinct holders. A real launch pulls in many wallets fast; a handful of holders means the "community" may be one person on several addresses. Few holders + high concentration is the classic set-up for a dump.

🔴 under 5 holders — thin/suspect 🟡 5–50 — still early 🟢 hundreds+ — broadly distributed
5

Top-5 grip — do a few wallets own the float?

Even if no single wallet looks scary, add up the five largest wallets combined. If the top 5 hold the vast majority of minted supply, a small coordinated group controls the price — a soft rug waiting to happen.

🟡 65%+ combined — concentrated 🔴 85%+ combined — a handful own it all
Why people still get rugged

You can't run this by hand mid-mint

The checklist is simple to read and brutal to run in real time. During the Toccata wave, launches fill in minutes, the numbers move every block, and the fear of missing out is loudest exactly when the data is thinnest. That's when people ape first and check never.

The fix is to have the five signals computed for you the instant a launch appears. Our free Fair-Launch Radar pulls each token's live Kasplex data, runs this exact penalty model — pre-mint, top-wallet, deployer, holder spread, top-5 — and prints a single A–F grade with the reasons spelled out. Green means the signals check out; red means walk away. No spreadsheet, no block explorer, no guessing.

It's free and read-only — checking a grade never touches your wallet. New to any of these terms? Start with what the Toccata upgrade is or how a KRC-20 token is created.

The checklist, automated and graded

Every live launch, scored on the five signals above — so a fair launch and a rug stop looking the same.

🔎

Reads the on-chain signals

Pulls each token's public Kasplex data — pre-mint, holder balances, deployer stake — the moment it goes live. Real data only, no wallet access.

🅰️

Grades it A–F

Runs the transparent penalty model and prints one fairness grade with the reasons listed. A glance tells you whether the launch is spread out or insider-loaded.

🛡️

Mint safely, if you choose to

Decide to ape a clean launch? Mint non-custodially at a flat 1.75% — you sign every transaction from your own wallet, and pay ~3× less than the 5% bots.

Checked the grade? Mint without overpaying the bots.

Dodging rugs is half the battle; the other half is not bleeding fees on the good ones. The dominant minting bots quietly take 5%. The Fair-Launch Radar mints the same on-chain token for a flat 1.75%, non-custodial — you sign from your own wallet, and keep the difference.

KRC-20 rug pulls — FAQ

What is a KRC-20 rug pull?

A rug pull is when the people behind a token capture most of the supply — through a large pre-mint, a heavy deployer allocation, or a few coordinated wallets minting the bulk of the launch — and then dump it on later buyers, collapsing the price. On Kaspa's fair-launch model the tell-tale signs are on-chain and public, so you can read them before you mint.

How can I check if a Kaspa token is a rug before I mint?

Read five signals from its public data: pre-mint, top-wallet concentration, deployer self-allocation, holder count, and top-5 grip. Low pre-mint, spread-out holders and a light deployer balance point to a fair launch. The free Fair-Launch Radar computes all five and grades every live launch A–F automatically.

What counts as a dangerous pre-mint on a KRC-20 launch?

A true fair launch has zero pre-mint — no supply reserved before the public mint opens. Any pre-mint means the deployer starts with a stake the public couldn't earn; 5% or more is a clear red flag, and the bigger it is, the more they can dump on you later. The radar penalizes pre-mint heavily and flags anything above 5% in red.

Is a high top-wallet concentration always a rug?

Not always, but it's the single biggest risk signal. If one wallet holds 30–50%+ of minted supply, that wallet alone can crash the price. Early in a mint a little concentration is normal because few wallets have minted yet — but a launch that stays concentrated as it fills is dangerous. Read it alongside the other four signals.

Does the Fair-Launch Radar cost anything to check a token?

No. Checking any live launch's fairness grade on the radar is free and read-only — it only reads public Kasplex data and never touches your wallet. If you then choose to mint, it's a flat 1.75% fee (~3× cheaper than the 5% bots) and non-custodial. See the full fee comparison.
