      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.

      Software Development Review from Olena Shabunina

      We needed to quickly expand our dev team to build out a new feature set, and Hivex helped us find and bring on skilled remote developers to make that happen. The devs hit every deadline we set, sometimes even early. If we needed changes or had questions, they were super responsive - usually got back to us within a couple hours.

      We had a temporary gap in our technical team due to some transitions, and we needed to keep our development momentum going strong. Hivex provided us with skilled developers who seamlessly integrated into our team. They had the expertise we needed and filled the gap until we made permanent hires. Our collaboration with Hivex made sure our projects kept going without delay, we didn't lose our development momentum, and there wasn't any disruption. It was a huge help during a challenging time.

      Working with Suffescom has been an absolute pleasure. I approached them to develop an AI-powered car rental app, and I couldn’t be happier with the results. From day one, their team was professional, transparent, and truly understood my vision. They didn’t just build an app — they created a smart, user-friendly platform that uses AI to personalize the rental experience for users. The interface is smooth, the performance is fast, and the overall design looks world-class. What really stood out was how proactive their developers were — they offered great suggestions that made the app even better than I had originally planned. Communication was easy, deadlines were met, and every milestone was delivered with top-notch quality. Suffescom clearly knows what they’re doing when it comes to AI and app development. I highly recommend them to anyone looking to build a cutting-edge tech solution. Thanks to the entire Suffescom team for doing such an amazing job — this project has definitely exceeded my expectations!

7 Frequently Asked Questions About Blockchain Development Companies

What services do blockchain development agencies offer?

Blockchain development agencies design, build, and support blockchain-based solutions that automate processes, improve transparency, and enable secure digital transactions. 

Common services include: 

  • Smart contract development and auditing: Writing self-executing code and reviewing it to prevent bugs, exploits, or costly failures  
  • dApp development: Building decentralized apps that run on blockchain networks instead of centralized servers  
  • Token development and NFT platforms: Creating digital tokens, cryptocurrencies, and marketplaces for trading assets  
  • Blockchain integration: Connecting blockchain with existing systems like web apps, enterprise software, or cloud platforms  
  • Private and enterprise blockchain solutions: Setting up custom networks for businesses that need control, privacy, and scalability  
  • Blockchain consulting: Advising on use cases, architecture, and whether blockchain is the right fit  
  • Wallet development: Building secure wallets for storing and managing digital assets  
  • Maintenance and support: Monitoring performance, fixing issues, and updating systems after launch 

What platforms do blockchain developers use?

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: 

  • Ethereum: The most widely used platform for smart contracts and decentralized applications  
  • Solana: Built for high speed and low fees, often used for scalable dApps and marketplaces  
  • Avalanche: A flexible platform that supports custom blockchain networks and fast transaction finality  
  • Hyperledger Fabric: Designed for private, permissioned systems used by enterprises  
  • Corda (R3): Common in finance and regulated industries where data privacy is critical  
  • IBM Blockchain: Enterprise-grade solution built on Hyperledger for secure business use cases  

Development tools and infrastructure that blockchain development agencies use: 

  • Node providers (e.g., Alchemy, Infura, QuickNode): Give developers access to blockchain networks without running their own nodes  
  • Smart contract tools (e.g., Remix IDE): Used to write, test, and deploy contract code  
  • Frameworks and CLIs (e.g., Ignite CLI): Help set up and manage blockchain projects faster 

How much do blockchain companies charge for their services?

Blockchain development companies typically charge from $40,000 to $300,000+ for a full solution, depending on complexity, features, and security requirements. 

Cost by project complexity 

The biggest cost driver is the solution's complexity, from basic smart contracts to full-scale platforms. 

  • Simple blockchain apps: $40,000 to $60,000 
    Basic features like simple smart contracts or payment functionality  
  • Mid-level applications: $60,000 to $150,000 
    dApps with user roles, integrations, and moderate decentralization  
  • Complex blockchain systems: $150,000 to $300,000+
    Enterprise platforms, advanced security, custom architecture 

Cost by solution type 

Different blockchain products have different price ranges based on functionality. 

  • dApps: $35,000 to $150,000  
  • NFT marketplaces: $55,000 to $125,000  
  • Crypto wallets: $125,000 to $200,000  
  • Crypto exchanges: $135,000 to $190,000  
  • DAO platforms: $10,000 to $30,000 

Cost breakdown across the project 

Your budget is split across multiple phases, not just development. 

  • Consulting and planning: 5%  
  • UI/UX design: 10%  
  • Core development: 45%  
  • Testing and QA: 25%  
  • Deployment and maintenance setup: 15% 

Final pricing depends on scope, security level, integrations, and whether you build on an existing blockchain or create a custom one. 

What are the ongoing costs of maintaining a blockchain solution?

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: 

  • Maintenance and updates: Bug fixes, performance improvements, and feature upgrades  
  • Infrastructure: Node providers, cloud services, and storage as usage grows  
  • Security: Regular audits, monitoring, and protection against vulnerabilities  
  • Transaction fees: Ongoing network or gas fees for processing transactions  
  • Support and operations: Technical monitoring, DevOps, and user support  
  • Compliance: Legal, regulatory, and data protection requirements  

Costs increase as the system scales, handles more transactions, or requires higher security. 

How long does it take to build a blockchain solution?

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: 

  • Simple solutions: 1 to 2 months 
    Basic wallets or simple smart contract apps  
  • Mid-level projects: 2 to 4 months 
    dApps with integrations and user functionality  
  • Complex systems: 4 to 9+ months 
    DeFi platforms, marketplaces, or enterprise solutions  

Blockchain development agencies build products in stages, and each is adding time: 

  • Planning and requirements: 1 to 2 weeks  
  • Architecture and design: 2 to 4 weeks  
  • Development: 1 to 6 months  
  • Testing and QA: 2 to 4 weeks  
  • Deployment: 1 to 2 weeks 

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.

What is the difference between public and private blockchains?

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

How do blockchain development agencies ensure security?

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: 

  • Smart contract audits: Reviewing code to detect bugs, exploits, and logic flaws before deployment  
  • Secure development practices: Using proven frameworks, code standards, and peer reviews  
  • Encryption and key management: Protecting data with cryptography and secure storage of private keys  
  • Testing and simulation: Running stress tests and attack scenarios to identify weaknesses  
  • Access control: Limiting permissions and enforcing authentication for users and systems  
  • Ongoing monitoring: Tracking activity, detecting threats, and applying updates or patches quickly  

Security is built into every stage, not added after deployment.
