Snipers & Bundlers - Webacy Docs

Overview

Snipers and bundlers are traders who use automated tools to gain unfair advantages during token launches. They acquire large positions before regular users can participate, often leading to price manipulation and losses for retail traders.

Tokens with high sniper or bundler activity at launch often experience rapid price dumps. Check holder analysis before investing in newly launched tokens.

Snipers

What They Do

Monitor mempool for new token deployments
Execute buy transactions in the same block as liquidity addition
Pay high gas fees to front-run other buyers
Acquire tokens at the lowest possible price

How They Operate

Detection: Bot monitors for addLiquidity transactions
Front-running: Submit buy with higher gas fee
Acquisition: Get tokens before price moves up
Exit: Sell into retail buying pressure

Impact

Regular buyers pay higher prices
Snipers dump on later entrants
Creates immediate sell pressure

Bundlers

What They Do

Bundle multiple transactions into a single block
Often use private mempools (e.g., Flashbots)
Coordinate token launch + immediate purchases
Can control significant supply from block 0

How They Operate

Preparation: Create multiple wallets
Bundling: Package launch + buys together
Execution: All transactions in one block
Distribution: Spread holdings across wallets

Impact

Supply concentration from first block
Artificial holder count inflation
Coordinated dump capability

Detection Indicators

Tag	Severity	Description
`has_been_sniped`	Medium	Token was sniped at launch
`bundled_token`	High	Token launch was bundled

Holder Analysis Tags

Tag	Description
Sniper percentage	% of supply held by identified snipers
Bundler percentage	% of supply from bundled transactions
Block 0 holders	Wallets that bought in the launch block

API Example

# Get holder analysis for a token
curl -X GET "https://api.webacy.com/holder-analysis/So111...?chain=sol" \
  -H "x-api-key: YOUR_API_KEY"

Early holder analysis covers Solana tokens launched within the last 12 months and BSC tokens deployed within the last 3 months (data provider retention). Older tokens return data_availability: "unsupported_token_age"; previously analyzed tokens continue to return stored results.

Red Flags at Launch

Indicator	Risk Level
>30% sniper holdings	High
>20% bundler holdings	High
>50% in block 0	Critical
Fewer than 10 unique block 0 wallets	Suspicious
Rapid holder count increase then plateau	Manipulation

Protection Strategies

Wait before buying - Let initial volatility settle
Check holder analysis - Use our Holder Analysis endpoint
Monitor distribution changes - Healthy tokens show gradual distribution
Verify team holdings - Transparent teams disclose their wallets
Watch for coordinated sells - Snipers often dump together

Legitimate vs Malicious

Not all early buyers are malicious: Legitimate Early Buyers:

Team/investor allocations (disclosed)
Presale participants
Community members with advance notice

Malicious Actors:

Undisclosed insider wallets
MEV bots with no project relationship
Coordinated dump groups
