NodeJs

Command for install dependencies

After the node installed, we must execute some commands to install the dependencies that the project needs.

1. Installing Yarn

npm i yarn -g

2. Installing all dependencies of the project

yarn install

Now, you can run the tool baby!

To execute the application you need to have a COVALENT API KEY, because we use the COVALENT API to get all the holders of the contract. When you have a COVALENT API KEY you can run the command below:

yarn start --covalent-key=ckey_xxxxxxx

The output of this execution will be a file with the holders and theirs NFTs.

The first goal of this tool is find all the holders of the contract: 0x48f9f93ba55852f7ba5beb55ad9d9cee373c0ad4, and for this we use the COVALENT API that allow us to read some data of the blockchain.

The second goal is find the NFTs for each holder that we found in the step 1. To do that we use the ZooApi that retrieve for each wallet theirs NFTs.

The thirty goal is push all the information found in the report file. The report file will be generated as "zoo-nft-report.csv" and will contain: wallet, nft id, level, rarity and illegal status.
