Adding a new blockchain / smart contract

• Configure the config file
• Create a new db
• Create an info collection in the db
• Implement all the functions mandatory in the utils' retrieveAndAnalyzeTxs function.
• In the infoAndStatusDB, add all the mandatory functions

Adding a new collection into terra algo

• add the contract in terra/config

"luna_bulls_tesseract": "terra1k5pa7htlznr7hskhr9dx8qlk65emhktrgmuknd"

• add the collection config in terra/config

{"name": "styllar", "triggerFactor": 3, "rarityFactor": 3},

• If you want to add a special function for special fields, you can do it by adding it in the collectionToFunction map.

Buying algorithm

In order to determine if we buy an item or not, we compare the price of the cheapest item with the price of the second cheapest item. Each collection has a triggerFactor parameter. It has to be between 1 and 5. Here is what it means:

• 1 means we trigger if the price is 90% below the real price
• 2 means we trigger if the price is 60% below the real price
• 3 means we trigger if the price is 40% below the real price
• 4 means we trigger if the price is 25% below the real price
• 5 means we trigger if the price is 15% below the real price

Moreover, if the collection supports it, the algorithm looks at the rare items and buy them if they are close to the floor and below a certain rarity percentage. This percentage is determined by the rarityFactor defined in the collection's config. It has to be between 1 and 5.

• 1 means we trigger if an item with a rarity of 2.5% or below is close to the floor price.
• 2 means we trigger if an item with a rarity of 5% or below is close to the floor price.
• 3 means we trigger if an item with a rarity of 10% or below is close to the floor price.
• 4 means we trigger if an item with a rarity of 25% or below is close to the floor price.
• 5 means we trigger if an item with a rarity of 40% or below is close to the floor price.

Set up the mongo db

1. Create the terra db

use terra

2. Connect compass

mongodb://192.168.0.15:27017/terra?readPreference=primary&appname=MongoDB%20Compass&directConnection=true&ssl=false

3. Use the script (and modify it) to import data. Don't forget to add token_id index in each collections.
