6 Reasons Why You Need to Leverage Our Technical Expertise for Blockchain Development


To save money through control

Due to the increase of hacker attacks, it is cheaper to invest in blockchain technology today than to deal with the financial consequences of a possible data leak.


To keep data immutability

Decentralized data and complicated automated encryption provide reliability, ensuring that if one block breaks, your data still remains in place.


To stay anonymous and save

Joint real estate ownership, trading, or making cross-border payments in complete anonymity is another bonus that blockchain technology offers.


To monitor quality and provide transparency

Blockchain technology allows watching the logistics of goods in real-time, offers a retention schedule and delivery information, and reduces the number of counterfeits.


To Reduce Human Errors and Accelerate Processes

Due to the real-time technology, IoT operating systems already work in state security and civil aviation departments. This leaves difficult decisions to the machine.


To decrease the level of bureaucracy

Signing contracts, financial transactions, and issuing diplomas and passports – all these can be performed online with 100% security with the help of blockchain technology.

Blockchain App Development FAQ

  1. How much do blockchain app development services cost?

    Several factors affect the cost of blockchain app development services. Key elements include the app’s complexity, amount of features, timelines, available budget, and cooperation model with a blockchain application development company.

    However, the average price for blockchain app development ranges between $40,000 to $300,000. It is best to either hire an augmented team or outsource the entire process to a trusted provider instead of hiring freelancers or creating your own in-house team. These options are more cost-effective solution.

  2. How long does it take to build a blockchain app?

    The time needed to build a blockchain app depends on the project scope, team creating it, the complexity of the software, and the developers’ expertise. The average duration for developing a blockchain app ranges between 4-6 weeks and 12-18 months.

  3. How can I hire the right developers from a blockchain application development company?

    The team you hire for the blockchain development will affect the quality and stability of the app you will receive at the end of the process. So, there are several factors you should consider when you decide to hire blockchain app developers from a company rather than freelancers. 

    We recommend focusing on a company’s expertise in blockchain solutions development, reviews on trusted platforms like Upwork and Clutch, the team’s communications skills, projects they’ve already worked on, and the tech stack they use to verify they can cover your needs. One of the top blockchain app development companies, Interexy has a reputation for building all its projects with expertise.
