Web Development Review from Alexander Nikolaevsky
We have hired the Plavno team to develop a cryptocurrency exchange solution.allow users to make cryptocurrency transactions legally and transparently. Plavno team had to create a solution independent of third-party developers, develop frontend solutions for clients and service administrators, build a full-featured back-end that would include integration with banking and payment systems, and a multifunction module for managing currency exchange transactions, exchange rates.

Financial Review from Mitya Smusin
Some problems can only be solved with code, but others require end-user thinking. So Plavno developers remember that the whole goal is to solve problems — not only to write code. They thought about the problem from the restaurantants point of view.They developed a food delivery app with both customer and admim panels, which covers all the necessary functionality.
IT Outsourcing Review from Yana Romanovskaya
Plavno was creating profiles with pulling up a lot of information (clusters). Xunit-based scoring was used when setting up a .NET 2.0 project. Scoring for this format works similarly to Junit. The team extended the products by adding features, fixing bugs. This development can change cluster parameters, cluster management system (current state of the object), customize vectors that lead to this cluster and make predictions.

We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor.

They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

Before hiring blockchain development firms, you should define clear business goals, technical requirements, and budget expectations so developers can accurately scope the project and avoid delays.
Key information to prepare:
Clear input helps the developer give accurate timelines, costs, and solutions.
Blockchain development firms deliver the most value in industries that depend on secure data sharing, multiple stakeholders, and high trust, with finance, supply chain, and healthcare leading adoption. The global blockchain market is projected to reach $393 billion by 2030, showing rapid growth across sectors.
Across these industries, a blockchain development company can reduce manual work, increase trust, and replace fragmented systems with shared, reliable data.
Blockchain development companies help your business move from traditional, centralized systems to decentralized ones that improve security, transparency, and automation.
In 2026, the global blockchain market is expected to reach $47.96 billion (up from $31.18 billion in 2025), indicating that these companies are no longer just for crypto startups but are now important to modern enterprises.
Here are four key ways a custom blockchain development company can transform your business:
Blockchain developers remove the need for intermediaries by replacing them with automated systems. This is especially useful in global transactions and internal audits.
A blockchain company builds systems that store data in a way that cannot be changed and distribute it across multiple locations, reducing the risk of a single point of failure.
Blockchain developers can connect IoT sensors to a shared ledger, allowing real-time tracking of goods that cannot be altered. This is critical for industries like pharma, food, and manufacturing.
By embedding business rules into blockchain systems, smart contracts automatically trigger actions such as payments or approvals when conditions are met.
Check experience by looking for direct proof that the blockchain development firm has already built and delivered solutions similar to yours, not just general development claims.
What to verify:
Asking the right questions before signing a contract with a blockchain development firm helps you avoid risks, validate expertise, and ensure it can deliver a secure, scalable solution.
Rated 4.8 on Google and 4.7 on Trustpilot, DesignRush Agency Directory is a reliable resource for finding blockchain development companies. We owe this to our executive selection team, which follows a strict screening process when featuring agencies on the platform, assessing key performance indicators, like portfolio, client reviews, and industry reputation.

DesignRush sustains a directory of over 40,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:
Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.
Blockchain development agencies design, build, and support blockchain-based solutions that automate processes, improve transparency, and enable secure digital transactions.
Common services include:
Blockchain development firms use a mix of public networks, enterprise platforms, and developer tools to build, deploy, and manage blockchain solutions. They choose platforms based on speed, cost, scalability, and whether the project needs a public or private network.
Key platforms and networks:
Development tools and infrastructure that blockchain development agencies use:
Blockchain development companies typically charge from $40,000 to $300,000+ for a full solution, depending on complexity, features, and security requirements.
The biggest cost driver is the solution's complexity, from basic smart contracts to full-scale platforms.
Different blockchain products have different price ranges based on functionality.
Your budget is split across multiple phases, not just development.
Final pricing depends on scope, security level, integrations, and whether you build on an existing blockchain or create a custom one.
Ongoing blockchain costs typically range from 15% to 25% of the initial development cost per year, depending on system complexity and usage.
Key ongoing costs include:
Costs increase as the system scales, handles more transactions, or requires higher security.
The best blockchain development company typically needs 3 to 9+ months to build a blockchain solution, depending on complexity, features, and security requirements.
Typical timeline by complexity:
Blockchain development agencies build products in stages, and each is adding time:
Factors that affect the timeline include scope and feature set, choice of blockchain platform, team experience, and whether you build from scratch or use existing tools.
Public blockchains are open to anyone, while private blockchains are restricted to approved users and controlled by an organization.
You can see the main differences in the following table:
| Feature | Public blockchain | Private blockchain |
| Access | Anyone can join | Permission required |
| Control | Decentralized | Controlled by one entity or group |
| Transparency | Fully transparent | Limited visibility |
| Speed | Slower | Faster |
| Cost | Higher (transaction fees) | Lower |
| Security | High through decentralization | High, but depends on governance |
| Use cases | Crypto, DeFi, NFTs | Enterprise systems, internal operations |
Blockchain development firms ensure security by combining secure coding, testing, and continuous monitoring to prevent vulnerabilities and protect data and transactions.
Key security practices include:
Security is built into every stage, not added after deployment.
