There are two currencies in the market, $BABY & $MILK. $BABY is a lot more valuable than $MILK.
Targeting the cheap baby in the marketplace. Let’s say the floor price of a baby at the moment is pricing at 20 $BABY. If a careless guy lists his baby at 10 $BABY, then the bot will buy it once the baby is listed.
How do bots do it?
Easy. Just keep tracking the market contract and use the “fillOrder” function to buy the targeted baby.

Targeting the bot in the marketplace by changing the currency. It baited the bots to buy the baby with the wrong currency.
If you look into the input data of the “fillOrder” function, it requires 2 parameters, NFT id & price. It doesn’t care what currency is used because the currency was fixed when the baby is listed on the market.
How do sniper bots do it?
Scenario: Bots that buys all babies with<2000 $MILK or <20 $BABY.
The sniper bots will perform fast combo transactions:
1. Listing baby with 50 $MILK (0.3 USD).
2. Cancel listing.
3. Listing baby with 50 $BABY (75 USD).
When the bots find someone is listing a baby with their target price, they will call the “fillOrder” function immediately, i.e. fillOrder(NFT id, 50). Then they were baited with the combo and resulting in buying the baby with 50 $BABY.
Targeting the sniper bots in the marketplace by breaking their combo.
How do anti-sniper bots do it?
The sniper bots will perform fast combo transactions. How if the anti-sniper bots are faster than the sniper bots? Buying the cheap baby before they cancel the listing order?
1. Listing baby with 50 $MILK (0.3 USD).
— anti-sniper bots bought it
X. Cancel listing.
X. Listing baby with 50 $BABY (75 USD).
To conclude in a simple word — fast.
- Bots can buy cheaper babies than humans because they are faster than humans.
- Sniper bots baited bots because they are faster than normal bots.
- Anti-sniper bots killed sniper bots because they are faster than sniper bots.
How to become fast is a complicated topic that is affected by many elements. It depends on your knowledge of blockchain, coding skills, equipment… The road is long to learn.
