Coretechs Consulting Reviews & Testimonials
John Mehner's Review Sourced from Google
Coretech has been an extremely valuable partner for the last 6 years. We started by re-writing our entire web application at the time - they were on-time, on-budget, and had a very strong team to help with the implementation. Since then we continue to use them as an extension of our team for enhancements, new features, bug fixes and the rest. Their wisdom and understanding of choosing the right approach and technologies has been invaluable. Honestly can't speak highly enough about the team, thank you Gil and team!
Risa Hubble's Review Sourced from Google
The team at Coretechs is phenomenal. We needed to transition our custom app and databases to a new developer rather quickly due to an unexpected discontinuation of service. Coretechs handled all of the details and made the transition absolutely seamless. They communicated their progress and timelines the entire time. Since then I've had them do some modifications to our app, which they turned around right away. Everyone I've talked to there is super friendly and super knowledgeable. I'm looking forward to working with them on future improvements.
Conway Li's Review Sourced from Google
Coretechs is a great consultancy! They've supported one of our products that we inherited from another company. They are prompt to respond, and their pricing is fair.

ajay Jaryal's Review Sourced from Google
I started at KodeGrid as a trainee. I was new, excited, and a little nervous. But from the first day, everyone here was super welcoming.Now I’m learning new things every day and also working on real projects — mostly using WordPress and HTML. It feels great to see my work actually being used.Happy to be part of the KodeGrid team and thankful for the support.
Banger Akash's Review Sourced from Google
I've been working at Kodegrid for the past three months, and it's been an incredibly positive experience. From day one, I felt welcomed and comfortable. The environment here is super friendly and supportive — all the seniors treat me more like a college friend than a junior colleague, which makes learning and collaborating really smooth and enjoyable.What I appreciate most is how approachable and helpful everyone is. There's no hierarchy barrier when it comes to asking questions or seeking guidance. In just a few months, I've learned so much — not just technically, but also in terms of how to work in a real-world development environment.Kodegrid is the kind of place where you grow every day while enjoying the process. I'm genuinely grateful to be a part of this team!

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.
