Mass NFT listing on Unique Market

These scripts are for those who have already minted a large NFT collection and want to list many tokens on the Unique Market. They can help you put NFTs up for sale quickly without manually signing every transaction.

⚙️ Step-1: Setting up environment

1. You will need node.js, git, and Visual Studio Code installed on your computer. If you haven't worked with git, node, and npm before, we recommend reading our brief guide to configure your environment.
2. Download this project and open it in Visual Studio Code, click File - Open Folder...
3. Create a file named .env in the root directory of your project and copy the contents from the .env.example file into it.
4. In the .env set SUBSTRATE_SEED with a 12-words mnemonic secret phrase of the NFTs owner. Set COLLECTION_ID with the id of your collection. Remember to save the file!
5. Install dependencies. Open VS Code built-in terminal by clicking Terminal - New Terminal. In the terminal window that appears, enter the command:

npm install

Important

Keep your secrets, such as SUBSTRATE_SEED, safe, and do not commit them to version control! We have added .env to the .gitignore file for this purpose.

In this step, your project should resemble the screenshot below:

📄 Step-2: Get your NFTs list

Create a .csv file with a list of tokens that belong to you. Run in terminal:

npm run build

After executing the script, the collection_123.csv file will be created in the root of the project with the contents:

token id	price
1	1
2	1
3	1

All your tokens from the specified collection are registered in the table. All tokens have a default price of 1. Change these prices to your liking and save the file. Prices are expected to be written without decimals, so 1 in the price cell means 1 000 000 000 000 000 000 in a contract.

Set the desired price for the tokens you want to list on Unique Market and remove all the tokens you don't want to sell.

We set tokens 1, 2, 9, and 10 for sale here. Tokens 1 and will be listed for 300 UNQ. Tokens 9 and 10 for 500 UNQ

🎁 Step-3: List your NFTs for sale

To put up for sale all the tokens in the created .csv file for the price specified in the file, run the script:

npm run sell

It will take some time, and in the end, you will see your tokens listed for sale on Unique Market.

Delist

To remove all the tokens from the created .csv file from the sale, run the script

npm run delist
