SpookySwap BooBrew $BOO Bounty Claim

SpookySwap collects protocol fees in the form of liquidity tokens and collects them in a contract they call "BooBrew".

This script was made to call the "ConvertMultiple" function on the BooBrewV3 contract.

This function will liquidate the liquidity tokens in the BooBrew contract and then convert it all to the native SpookySwap token, $BOO.

In exchange for calling this funtion, the caller will receive 0.1% of the BOO collected. The rest will be converted to xBOO to buyback BOO tokens and reward stakers.

BooBrewV3 Contract: https://ftmscan.com/address/0x3b3fdc40582a957206aed119842f2313de9ee21b

This script will watch the SpookySwap router for new pairs being swapped to add to the database.

It will then watch each new block for changes in the LP tokens held by BooBrew.

If a change happens, the pair is run through a local Hardhat node to see if the rewards meet the profit thresholds in terms of FTM to run the convertMultiple function inside the BooBrew contract.

Tools Used to Create This System:

• Node.js
• Ethers.js
• Hardhat Runtime Environment
• MongoDB Community Edition

Node.js // Ethers.js

Install the dependencies with npm by issuing the following command

npm install

Copy the .env.example to .env and change the variables to your own.

The PRIVATE_KEY_LIVE should include the 0x prefix.

Hardhat Runtime Environment

Hardhat is being used to simulate the bounty claim to determine how much rewards will be received from the claim.

Install HardHat - https://hardhat.org/getting-started#installation

I highly recommend giving the Hardhat documentation a read through prior to use to fully understand how it works.

Start a Hardhat Node on the Localhost with the following command on a screen to keep it running indefinitely.

screen -S hardhatNode
npx hardhat node

You can detach this screen once you verify that it's running properly. It should continue to run after being detached.

MongoDB Community Edition

Install MongoDB - https://www.mongodb.com/docs/manual/administration/install-community/

MongoDB will be used to store all the liquidity pools being held by the BooBrew contract, as well as, the bounty reward information collected from Hardhat.

Once installed, there's nothing else to setup as MongoDB will create the database, collection and variables in the documents when they are populated by the script.

Running the Script

Once you have everything setup, it's time to run the script with the following command.

cd scripts
npx hardhat run main.js --network localhost

rewardsupdate.js

This script was made when there was a significant time period the main script was down.

It will update all the reward numbers and claim anything profitable in the meantime.

cd scripts
npx hardhat run rewardsupdate.js --network localhost

In order to run this update script, you need to have a database of pairs already established.

Optimization Ideas

• More Advanced Logging System: Using something like Graphana to see which pairs are the most profitable and which ones are giving the most issues.
• Remove Issue Pairs: Sometimes there are pairs that won't process. Would like to build a simple system that resets these pairs rewards data if they get an error in the Hardhat node.
• Auto-Restart Script: Hardhat will occassionally get an error that causes the main script to stop. Need to setup a system to automatically restart the script when it shuts down due to an error.
• Cancel Claims: When someone else makes a claim on an LP before processing our claim, cancel the claim with a self transfer with higher gas to try to save on gas costs, as much as possible.
