How Sniff scores a token, how a buy works and what you pay.

What Sniff is

Sniff is the first AI DEX on Solana. Paste any token to see its facts. Every launch gets a Data score from 1 to 10 that AI explains in plain words, and you buy with SOL from your own wallet.

A launch is a token that came from a Solana launchpad such as pump.fun. It trades on a bonding curve first, then moves to a pool.

The AI explains a score from the facts on the page. It doesn’t trade for you and doesn’t tell you what to buy.

Then buy it with SOL. One signature covers the whole buy, and the token arrives in your own wallet in about a second.

Sniff never holds your money. You sign every transaction yourself, and checking a token needs no wallet.

You can sell from the same form and receive SOL.

Data score

The Data score is a number from 1 to 10 computed from public on-chain data. It describes how a launch was set up and how it trades right now.

It is not a price call, a rating of the team or a promise of anything. A token with a high score can still lose value. Nothing here is financial advice.

How it’s counted

Two parts, each out of 10. The launch part carries 60% of the weight, the market part 40%. The result is rounded to a whole number, then any cap that applies limits it.

Launch60%
Market40%
Data score = 0.6 × Launch + 0.4 × MarketExample: 0.6 × 10 + 0.4 × 7 = 8.8, rounds to 9.

Launch, out of 10

Starts at 10. Each finding below takes points off, and one can add a point back. The launch part never drops below zero.

FindingPoints
New supply can still be mintedSerious−3
The token’s authority can freeze walletsSerious−2
Bundled wallets hold over 10% of supplySerious−3
Snipers hold over 15% of supplySerious−2
Snipers hold over 5% of supply−1
The deployer has 5 or more earlier launches and none moved to a poolSerious−2
The deployer launches at volume (20 or more) and almost none of it moves to a poolSerious−2
Four or more of the top holders were funded by the same wallet within an hourSerious−2
The deployer sold on this tokenSerious−2
The deployer bought over 12% of supply−1
Insiders hold over 10% of supply−1
Transfer fee above 3%−1
No socials declared at launch−1
The deployer had an earlier launch move to a pool and has not sold here+1

Any deduction keeps the launch part at 9 or below. A serious one, marked in the table, keeps it at 8 or below, whatever the bonus.

Market, out of 10

Four facts about trading right now. Buyers are the wallets that ended the last 24 hours holding more than they started with.

FactPoints
Buyersunder 10 → 0 · 10 to 29 → 1 · 30 to 99 → 2 · 100 to 249 → 3 · 250 or more → 4 max 4
Curve filledunder 5% → 0 · 5 to 19% → 1 · 20 to 49% → 2 · 50% or more → 3 · moved to a pool → 3 max 3
Last tradeunder 10 minutes → 2 · under an hour → 1 · older → 0 · moved to a pool → 1 max 2
Smart wallets3 or more → 1 max 1

A smart wallet has bought into 3 or more launches, and at least a quarter of them later moved to a pool. Sniff builds this list itself from the buyers it sees, so it grows over time.

Caps

A cap limits the final score, however good the rest looks. When several apply, the lowest wins. The token card names every cap that fired.

A serious launch findingmax 5
The deployer holds over 10% nowmax 5
The deployer holds over 25% nowmax 3
Based on what the deployer holds now. If that can’t be read, the card shows a dash.
No trades for 24 hours on the curvemax 4
Under 10 minutes old, data still coming inmax 7
Part of the data could not be readmax 8, marked partial

A 10 means nothing was found in the launch and the market is busy.

Tokens without a score

The Data score covers launches. Stock tokens have no launch to score, so their card shows price and facts without a score. Other tokens show their supply, with no score.

How buying works

Pay with SOL from your own Solana wallet. One signature buys the token, and it arrives in your wallet in about a second.

Sniff finds the route for you, across Solana’s bonding curves and pools, for the best price. If no route exists yet, for a very new token or a very small amount, you’ll see it before signing.

Before you sign

The review shows the minimum you will receive, the network fee, the transfer fee if the token has one, and the price impact. If the quote changes before you sign, you see the new numbers and confirm again.

Slippage

Slippage is how far the price may move before your buy lands. The default is 3%, and you can change it in settings. If the price moves further, nothing is bought.

After you sign

A buy arrives in about a second. If a confirmation is slow, the buy shows as still on its way, with a link to the explorer. Don’t buy again until it arrives.

Your activity list is kept only in this browser. Clearing site data removes the list, not your tokens.

Selling

Flip the form with the arrow between the fields to sell a token you hold. You receive SOL in your wallet.

A sale always takes one signature. Solana needs no separate approval step.

The review shows what you sell, what you will receive, the minimum received and the fees. The transfer fee applies to sales too, on tokens that have one.

Fees

Sniff charges no fee of its own. What you pay depends on the token, and every amount is shown before you sign.

Network feea fraction of a cent, plus a small priority fee
Pool or curve feeinside the price you are quoted
Transfer feeset by the token’s creator, on the few tokens that have one (Token-2022)
Account rentabout 0.002 SOL the first time you hold a token, returned if you close the account

Price impact is not a fee and doesn’t include the fees above. It is how much your own buy moves the price, and it grows with the size of the buy.

Sniff is an independent app built on Solana.

Wallets

Checking a token needs no wallet. You connect one only to buy or sell.

Connect the Solana wallet you already use: Phantom, Solflare, Backpack or any Wallet Standard wallet. No email is needed. Sniff doesn’t create wallets and never holds your money: you sign every transaction, and tokens arrive in your own wallet.

Solana wallets show new tokens on their own, so there is nothing to add after a buy.

API

The reads behind this site are open. No key, no sign up, and any site may call them from the browser.

  • GET /api/token/{address} takes a Solana token address: facts, its Data score and the flags behind it. 60 requests a minute.
  • GET /api/launches?sort=trending|recent|all&limit=50 scored launches, newest or most traded first.
  • GET /api/pulse chain numbers: slot, new tokens in 24 hours, how many launches are red-flagged.
  • GET /api/stocks the 27 stock tokens on Solana and their prices.

Answers are JSON and may be a few seconds old. A score is a reading of public on-chain data, not advice, so show it as the Data score from Sniff.

Updates and new features: @sniffdex on X.

Disclaimers

The Data score and the AI explanation are readings of public on-chain data at the time shown. They are not advice and do not predict prices.

New tokens are risky and can lose all of their value. Buy only what you can afford to lose.

A signed transaction can’t be reversed, by you or by Sniff. Check the review before you sign.

Stock token availability depends on where you live. The note at the bottom of this page lists the restrictions.
