{% hint style="warning" %}
**Warning**

Chainsniper PumpBot will only detect **NEW** Liquidity Add Events in Mempool: liquidity already added won't be detected \
\
\--> do not use it for already launched tokens
{% endhint %}

{% hint style="info" %}
**Info**\
There is no BUYPRICE with Chainsniper PumpBot: it buys at the price specified by the team when they add liquidity\
\--> BUYPRICEINBASE has been removed from tokens.json
{% endhint %}

## 1. First steps

{% hint style="info" %}
 Prerequisites :

* Windows operating system (your computer or a [VPS](https://en.wikipedia.org/wiki/Virtual_private_server), have a look at the FAQ)
  {% endhint %}

* Buy Chainsniper PumpBot at <https://pump-bot.com/crypto-bots/sniper-bot-frontrunner-chainsniper-dexbot/>

* Download Files, read the Guide and you are ready for Profits

Our bot works with 2 json files :

* settings.json
* tokens.json

## 2. Configure your settings and tokens

The only parameter who only exist in Sniper is in settings.json : MEMPOOL\_METHOD

* If you use **private** node : MEMPOOL\_METHOD = private\_node
* If you use **public** node : MEMPOOL\_METHOD = public\_node

One difference to notice : Chainsniper PumpBot is able to **detect which liquidity pair was used by the team**, and buy accordingly !

\
`Example:`\
Team adds liquidity in BUSD for LAMBO token --> Chainsniper PumpBot will buy with BNB > BUSD > LAMBO route

\--> no more "LIQUIDITYINNATIVETOKEN" and "USECUSTOMBASEPAIR" parameter :thumbsup:
