Blockchain Review from Sergei Bliznyuk
We've been working with Peiko on a complex blockchain infrastructure project, focused on building a custom Layer-2 scaling solution for our ecosystem. The goal was to reduce network congestion and lower gas fees, and their team has been involved from the initial discovery phase through ongoing development.What stands out most is their ability to turn complex blockchain concepts into practical solutions that align with real business needs. They don't just execute tasks, they actively contribute to shaping the product, helping prioritize features based on long-term goals. Their technical expertise is strong, and theyve delivered solid documentation, a clear backlog, and well-optimized smart contracts.Communication has been smooth overall. At one point, we adjusted the format of updates to get more visibility into the process, and they were quick to adapt and provide more detailed insights without any friction.The project is still ongoing, but the solution is already partially implemented and integrated into our ecosystem. So far, the collaboration has been professional, flexible, and well-managed.
Blockchain Review from Valeriia Subota
Peiko developed a complex stablecoin management platform for us from the ground up. They successfully took over the entire lifecycle, delivering critical technical documentation and UI/UX design where previous teams had struggled.The expertise of their Business Analysis team was exceptionalthey translated our vision into a robust technical architecture with precision. The high-quality MVP they delivered was instrumental in helping us secure VC funding. Throughout the process, the team maintained seamless communication and provided direct access to the developers, ensuring the project was completed exactly on schedule. A highly reliable choice for any high-stakes blockchain or fintech venture.
Blockchain Review from Catherine Ilashchuk
If you're building something technical, you know how easy it is for things to go off the rails. Peiko is the first team Ive worked with that actually got ahead of those issues before they started.Instead of just taking our money and starting to code, they forced us to slow down and nail the architecture and logic first. At the time, I just wanted to move fast, but that planning phase is the only reason we haven't had to rebuild half the platform mid-way through. They caught logic gaps we hadn't even considered.The communication is solid, no fluff, just direct updates on where we stand. They also didn't just build whatever I asked for; they pushed back when they thought a feature would bloat the MVP or mess with our timeline. Having a team that actually thinks about your budget and your launch goals like a partner, rather than just a vendor, makes a massive difference. Were heading into our next round of funding with a product that actually works and documentation that proves it.

Every time we had a question, they answered quickly and explained things clearly. We didnt waste time waiting for updates or chasing responses.Their technical work is solid. We asked for some custom solutions for our web3 development, and they handled even the tricky parts without any fuss. And they dont try to talk over your head with jargon. They keep things simple. The project cost was fair, with no hidden fees or surprise charges.We paid attention to the timeline, and ORKA delivered on schedule. The only delay we experienced was minor and well-communicated beforehand. I liked how the whole process was transparent. We always knew what was happening next.What stands out most is how willing they are to listen. If something was unclear, they fixed it fast. Our questions and suggestions were never ignored. Thats why I trust their team.In the end, our website looks good and runs reliably. It reflects what we wanted for our legal services business.

Unfortunately, there are no small, green omnipotent children, nor are there forest rangers, but there are a lot of smart people here and it kinda looks like an academic building in terms of architectural style.

Eugen Krenz's Review Sourced from Google
Absolute Non-Delivery and Ignorance of Client Needs - Legal Steps Being TakenI rarely write reviews, but my experience with Sumeru Inc. so abysmal that I feel compelled to warn others. I contracted this company for a high-value project, expecting professional and timely delivery as per their promises. What I received was nothing short of a disaster.Non-Delivery: Despite repeated assurances and deadlines, not only was the project delayed, but what was eventually sent was incomplete and of such poor quality that it was entirely unusable.Financial Duress: The sum charged for this project was exorbitant, especially considering that nothing of value was delivered. Payments were demanded under threats of halting the project, which now feels like outright extortion.No Source Code: Contrary to what was agreed upon, no source code files were provided, rendering any potential fixes or improvements impossible.Refund Ignored: Upon confronting them about these issues and asking for a refund, I was met with complete silence. My messages have been ignored, forcing me to take legal action.This has been a costly and time-consuming ordeal. I strongly advise against engaging with Sumeru Inc. Their lack of professionalism, poor execution, and complete disregard for their clients' needs are alarming. I am now in the process of taking legal steps to recover my losses.

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.
