1. Importance of Tracking NFT Minting​

Tracking the creation or "minting" of NFTs provides valuable insights into the dynamics of the NFT market. Developers need this data to manage NFT applications, update their backend, follow trends, identify new opportunities, or simply do some analysis.

2. Understanding Hal Stream​

Hal Stream is a powerful tool that allows developers to monitor blockchain data from specific contracts, wallets, or NFT collections. With Hal Stream, you can filter and query data based on specific conditions, all through a single REST API. The best part is that it requires no coding and supports multiple EVM-compatible blockchains including Linea.

3. How to Use Hal Stream on Linea to Track NFT Minting​

Because Linea is a zkEVM, it behaves the same way as any other EVM chains as far as setting up Hal Stream is concerned, enabling you to setup your monitoring with no friction while benefit from Linea’s fast and scalable throughput.

To use Hal Stream to monitor NFT minting on Linea, follow these steps: First, create a Blueprint by logging into your Hal account. Select "Contract Events ».

Data source selection

Next, enter the contract address of the NFT you want to monitor. Make sure this is a Linea NFT contract, in this example we’ll be using a test collection that we created using NFTS2ME.

Contract address

After adding the contract address, click "Continue". You will have the option to filter event data. To track NFT minting, you want to monitor the 'transfer' event, and more specifically, with the 0X0000… address in the ‘from’ field (as per the ERC-721 standard). To do this, select the event from the event list and click "Add filter" to specify the ‘from’ address.

Filtering

Finally, give your stream a name, then "Save and Deploy". Now, whenever an NFT is minted from the monitored contract, Hal Streams will capture the event data and make it accessible through a REST API using your API key. In your dashboard, you can see the stream alongside all the events that have been added to it, and an easy way for me to consume it.

Consume Hal Stream

When consuming this API, Hal stream will return a list of events that matched your filtering.

Example Stream output

If pulling the data from the API isn’t what’s best in your workflow, connectors will help Hal Stream push to your system directly, whether it’s using webhook, SQS or databases.
