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.

Software Development Review from Isammara Lourenço
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.

Kaushiki Gupta's Review Sourced from Google
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!

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

Security

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.
