How can you select the right partner from the listed Blockchain Development Companies?

The list of the above blockchain development companies curated by us is not conclusive. Despite the increasing adoption of the blockchain by various industries, it is still nascent technology in the market. There can be more reliable companies which can be considered as the top blockchain development companies.

While hiring the blockchain developer for your blockchain project, ask as many questions as possible and expect them to answer your queries eminently.

Here are some of the questions that you can consider before hiring a blockchain company

  1. How many blockchain solutions they have built?
    Though blockchain is still in its nascent stage, it is essential to consider the blockchain portfolio of a company while choosing them. Before you sign off a blockchain project with any organization, make sure that the blockchain company has provided scalable blockchain solutions to the startups or enterprises.Ask if the blockchain development company has worked on a public, permissioned or both platforms?

  3. What is the technology stack they work on?
    Knowing about the portfolio is not enough; you also need to ask what is the technology stack and tools used by the company to manage the projects.Ensure if the blockchain company works on the latest development tools and platforms or not. Hire a full stack development company that also has in-depth knowledge of various front-end and back-end technologies other than blockchain.

    Also, ask if they use enterprise-grade project management tools like Jira, Confluence or Pivotal Tracker to track the progress of every project.


  5. Where is the team located and if it works in your timezone?
    While you look out for a blockchain company, ensure to check the strength of the team.The size of the team shows how well a company can do and if they can complete the project within the decided time frame or not. Do not forget to ask where the development team is located and if they are available to communicate or work according to your timezone or not.

    Make sure to check the LinkedIn or other professional networks of the company’s technical experts to recognize their experience in the blockchain field.


The potential blockchain company should be able to identify whether your project needs the blockchain solution or not. Considering all these factors can help you find the right partner without any efforts.
