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.

Longwave Studio's work on the "Unblended" project has been nothing short of exceptional. This complex endeavor, involving the creation of a blockchain-based software solution, demanded a diverse skill set, and Longwave Studio delivered on every front.
The backend development is robust and reliable, providing a strong foundation for our blockchain-based system. The team exhibited a deep understanding of blockchain technology, ensuring data security and integrity were paramount.

Frontend development, both for the web and app interfaces, is nothing less than stunning. Longwave Studio's designers and developers have crafted an intuitive and visually appealing user experience that sets "Unblended" apart in its industry.
Communication and collaboration throughout the project were outstanding. Longwave Studio was responsive, accommodating, and receptive to feedback, ensuring that our vision for "Unblended" was fully realized.
The "Unblended" software has already made a significant impact on our operations, thanks to Longwave Studio's exceptional work. We couldn't be more pleased with the results, and we highly recommend their services to anyone seeking top-tier software development.
In a nutshell, Longwave Studio's development of "Unblended" has set a new standard for excellence in blockchain-based software, and we are excited to continue our partnership for future projects.

Our company aimed to launch a trading platform but struggled with security planning and system performance.

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.

Reviews verified by DesignRush and sourced from the agency's profile
View All Reviews
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?
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

Security
High through decentralization

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.
