Velas is an AI-powered delegated Proof-of-Stake (AIDPOS) which claims to have the capacity to process 50k+ t/ps without giving way to security or decentralization applications. It is a project that combines blockchain and innovative AI technologies to create a transparent, community driven, and decentralized ecosystem of product and services.
In this tutorial, we’ll take a look at how we can export account transactions and other details as a CSV file using Bitquery.
First of all, to get started, sign up on our Blockchain IDE and get you API keys. Then you can proceed to using Bitquery’s GraphQL IDE to get all your required data in the form of a CSV file.
To get started, let’s consider the details related to Velas blocks and try to extract them.
When you run the query in Bitquery’s GraphQL IDE, you can see the a drop down option against the word Ethereum in the lower section of the screen.
Upon clicking on the dropdown button, you need to select “Ethereum.blocks” and then moving towards the right, under the Using tab you need to select Table widget from the dropdown menu.
Using the plus sign at the bottom of the scree you can add the columns that you would like to have in your CSV file. For this example, we’ll be adding the height, transaction count and reward currency symbol.
Clicking on the CSV button you can download the CSV file easily.
You can add or delete columns as per your own convenience in the file and get the required data in the CSV format.
You can get the above query using the following link
Let’s consider another example in which we’ll try to get the table for transfers.
Here we’ve taken six columns, namely the timestamp, amount, currency symbol, currency address, sender’s address and receiver’s address .
For the display, we have chosen Ethereum.transfers from the dropdown menu here and under the Using tab, we have opted for the Table Widget. After clicking on the view button we get the following CSV file.
You can even change the view to JSON to get the results of your query in case you don’t need a CSV file.
This is how easily you can get all your desired information in the form of a downloadable CSV file.
