Working with LuminoGuru has been an incredible experience. From the beginning, their team was punctual, communicative, and fully committed to making the process smooth and stress-free. They helped develop our platform for Society of Scholars (SOS), and the quality of work exceeded expectations. What stood out the most was their ability to stay on schedule and maintain clear, consistent communication throughout the entire project.

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
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.
