DxSale sniper bot

Purpose

This bot allows you to compete with other trading bots when buying a cryptocurrency which is going to be on presale on DxSale launch platform.

Features

• Including transaction options like gas price, gas limit, etc
• Multi-address transactions ( by default DxSale presale allows each address to participate once at a particular sale so you can setup multiple addresses to join the presale )
• Supporting milliseconds
• Free

Requirements

• npm 6.0.0 or above
• NodeJS 10.0.0 or above
• pm2

Installation

Clone this repository ( or download from Code -> Download ZIP ) and run npm install inside the project folder. This command will download all the needed libraries which the bot needs to work properly.

Usage

You can run the script using node or pm2 commands. I personally like to use the pm2 command on my server, because PM2 is a process manager which takes care for my script to run 24/7.

Required parameters:

• dxSalePresaleContractAddress - this is the DxSale presale contract address ( not the contract address of the token you're willing to buy ). String, 42 bytes size starting with 0x. Example: WARNING! - This is a sample Presale address, do not use it! Each token DxSale has unique Presale contract address.

• buyingBnbAmount - this is the amount of BNB which you are willing to use to execute the buying transaction. Integer or float.

• senderPrivateKey - this is the private key of the wallet address which will be used to execute the buying transaction. For multi-address transactions then list the private keys separated by ,. ( Example - senderPrivateKey=0x8da4ef21b864d2cc526dbdb2a120bd2874c36c9d0a1fb7f8c63d7f7a8b41de8f,0x3da3ef21b123d2cc526dbdb2a120bd2874c36c9d0a1fb7f8c63d7f7a8b42de8E. ) Each private key have to have 66 bytes size starting with 0x. If you're using MetaMask then you will have to manually add 0x at the beginning of your private key, because MetaMask is displaying the private key with 64 bytes size.

Optional parameters:

• gasLimit - the maximum amount of gas you are willing to consume on a transaction, default value is 500000.
• gasPrice - the transaction gas price in Gwei, default value is 10 Gwei.
• createLogs - boolean, if set to true it will create ./logs folder and save logs on different bot actions.
• cronTime - how often should the bot try to buy the particular token. Default is '*/100 * * * * * *' aka every 100 milliseconds.
• botInitialDelay - by default when starting the bot for first time it has 10 seconds delay to double check what parameters have been passed. Setting this parameter to 0 will remove the delay if needed.

Sample terminal command:

• Using node - node dxsale-sniper-bot.js -- dxSalePresaleContractAddress=0xab5801a7d398351b8be11c439e05c5b3259aec9b buyingBnbAmount=0.5 senderPrivateKey=0x8da4ef21b864d2cc526dbdb2a120bd2874c36c9d0a1fb7f8c63d7f7a8b41de8f createLogs=true gasPrice=25
• Using pm2 - pm2 start dxsale-sniper-bot.js -- dxSalePresaleContractAddress=0xab5801a7d398351b8be11c439e05c5b3259aec9b buyingBnbAmount=0.5 senderPrivateKey=0x8da4ef21b864d2cc526dbdb2a120bd2874c36c9d0a1fb7f8c63d7f7a8b41de8f createLogs=true gasPrice=25

If you wish to use the bot at same time for multiple crypto tokens you could make several pm2 instances by passing --name parameter to the pm2 command. Example: --name "app name".
