      Software Development Review from Mario Mariani

      We worked in collaboration with Longwave for several projects, including the new version of our Junior Full Stack Developer Course, also having them onboard as teachers. Moreover, I've been working with some of them in another company as I was part of a senior management team. But in the end they are a software development agency, so I am happy to write this review of Longwave Studio to which we outsourced the implementation of our new product that is still in stealth mode. Longwave Studio exceeded our expectations in every way, from planning and designing to developing and delivering the product. They worked closely with our team to understand our needs and vision, and they developed a comprehensive plan to bring our product to life. They were also incredibly responsive to our feedback and made changes as needed to ensure that we were happy with the final product. Longwave Studio's team of experienced developers is highly skilled and knowledgeable in the latest software development technologies. They used their expertise to develop a robust and scalable platform that meets all of our needs. We are extremely pleased with the resultl that Longwave Studio brought to us. It will definitely help us to streamline the business processes and become very effective in what we do. We are confident that we would not have been able to develop such a successful platform without Longwave Studio's help. We highly recommend them to any company looking for a reliable and experienced development partner.

      Software Development Review from Hannes Rössler

      I worked with the Longwave agency on a software project for US physicians involving employees from several teams on our side. The collaboration with Longwave was very easy and straight forward. Everyone in their team had a great can-do attitude and the solution suggestions and execution were extremely professional. Longwave was responsive to all our request and made to find pragmatic, yet reliable ways of executing. Throughout the entire project the agency made proactive proposals how to best move forward and sticked to all their committed timelines. When we moved the project to maintenance mode several different options were offered and Longwave was really helpful in making sure we found the best way to continue collaborating. It was great to have a variety of skills in the agency, including design, backend, web frontend and mobile development. I can strongly recommend this agency for any sort of software project.

      I had the pleasure of working with Debut Infotech for DeFi development, and I am extremely satisfied with their expertise and service. Their team utilized a comprehensive suite of tools, including smart contract generators, DeFi protocol integrators, and liquidity pool management tools, all of which streamlined the development process. They not only helped us build secure and scalable decentralized finance solutions, but also provided automated yield farming and staking platforms that significantly boosted user engagement. Their focus on security, with built-in auditing tools, gave me confidence throughout the project. I highly recommend Debut Infotech to anyone looking for reliable, efficient, and innovative DeFi development.

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.
