Anti-whale Mechanisms in Polygon: Prevent pump and dump
In crypto, “whales” are individuals or entities that hold large amounts of a specific token.
Whales can bring certain advantages. Many token creators make deals with whales to boost marketcap, but they can also create real risks for the stability and fairness of a token ecosystem.

To address these risks, several anti-whale mechanisms have been created, and you can set them up with the anti-whale tool from Smithii.
In this article, I’ll walk you through the main anti-whale mechanisms, then cover the potential upside of having whales in your token ecosystem.
Anti-whale Mechanisms
The most common anti-whale mechanisms work by setting a maximum limit on token transfers.
Setting a cap on how many tokens can be transferred in a single transaction helps prevent sharp price moves, but there are other mechanisms too:
- Holding Limits: Setting a maximum percentage of the total token supply that any one address can hold helps keep token distribution more balanced. This prevents whales from having too much control over the token ecosystem.
- Time-Locked Contracts: Using smart contracts to lock tokens for a set period can stop whales from dumping large amounts of tokens into the market all at once. This creates a more gradual token release and supports price stability.
Anti-Whale Setup for Your token
You can configure anti-whale mechanisms with the Smithii tool by following these steps:

- Connect your wallet: Use the button in the top right to connect your wallet.
- Select the token you created
- Set the per-transaction limit: Enter the maximum amount allowed per transaction to keep whales in check.
- Set the per-block limit: Same idea as the previous step.
Benefits of having whales trade your token
Before wrapping up, I also want to point out that having whales trading your token can come with real upside.
So keep in mind that having whales in your Liquidity Pool is not always a bad thing, since they may be the ones providing liquidity, or a large share of it.
On top of that, plenty of people build tracking tools and watch wallets flagged as whales closely. So once a whale starts trading your token, a lot more people may jump in and follow the move.
