eCommerce Review from Mahil Jasani
We hired aPurple to build an MVP for our modest fashion e-commerce startup based in the UAE. The team at aPurple understood our vision from day one and helped us turn it into a working mobile app within just 10 weeks. Their process was structured but flexibleperfect for an early-stage startup like ours.They helped us define key features, set realistic milestones, and made sure the MVP aligned with our target audience. Communication was smooth, and their suggestions often added real value to the product.The final app had all the core features we needed to go live and test the market, and it performed well with real users. Thanks to aPurples support, weve now started onboarding suppliers and planning for scale.If you're a startup in the UAE looking to build a solid MVP with speed and quality, Id highly recommend aPurple.

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.Â
Common services include:Â
- Smart contract development and auditing: Writing self-executing code and reviewing it to prevent bugs, exploits, or costly failures Â
- dApp development: Building decentralized apps that run on blockchain networks instead of centralized servers Â
- Token development and NFT platforms: Creating digital tokens, cryptocurrencies, and marketplaces for trading assets Â
- Blockchain integration: Connecting blockchain with existing systems like web apps, enterprise software, or cloud platforms Â
- Private and enterprise blockchain solutions: Setting up custom networks for businesses that need control, privacy, and scalability Â
- Blockchain consulting: Advising on use cases, architecture, and whether blockchain is the right fit Â
- Wallet development: Building secure wallets for storing and managing digital assets Â
- Maintenance and support: Monitoring performance, fixing issues, and updating systems after launchÂ
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.Â
Key platforms and networks:Â
- Ethereum: The most widely used platform for smart contracts and decentralized applications Â
- Solana: Built for high speed and low fees, often used for scalable dApps and marketplaces Â
- Avalanche: A flexible platform that supports custom blockchain networks and fast transaction finality Â
- Hyperledger Fabric: Designed for private, permissioned systems used by enterprises Â
- Corda (R3): Common in finance and regulated industries where data privacy is critical Â
- IBM Blockchain: Enterprise-grade solution built on Hyperledger for secure business use cases Â
Development tools and infrastructure that blockchain development agencies use:Â
- Node providers (e.g., Alchemy, Infura, QuickNode): Give developers access to blockchain networks without running their own nodes Â
- Smart contract tools (e.g., Remix IDE): Used to write, test, and deploy contract code Â
- Frameworks and CLIs (e.g., Ignite CLI): Help set up and manage blockchain projects fasterÂ
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.Â
Cost by project complexityÂ
The biggest cost driver is the solution's complexity, from basic smart contracts to full-scale platforms.Â
- Simple blockchain apps: $40,000 to $60,000Â
Basic features like simple smart contracts or payment functionality  - Mid-level applications: $60,000 to $150,000Â
dApps with user roles, integrations, and moderate decentralization  - Complex blockchain systems: $150,000 to $300,000+
Enterprise platforms, advanced security, custom architectureÂ
Cost by solution typeÂ
Different blockchain products have different price ranges based on functionality.Â
- dApps: $35,000 to $150,000Â Â
- NFT marketplaces: $55,000 to $125,000Â Â
- Crypto wallets: $125,000 to $200,000Â Â
- Crypto exchanges: $135,000 to $190,000Â Â
- DAO platforms: $10,000 to $30,000Â
Cost breakdown across the projectÂ
Your budget is split across multiple phases, not just development.Â
- Consulting and planning: 5%Â Â
- UI/UX design: 10%Â Â
- Core development: 45%Â Â
- Testing and QA: 25%Â Â
- Deployment and maintenance setup: 15%Â
Final pricing depends on scope, security level, integrations, and whether you build on an existing blockchain or create a custom one.Â
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. Â
Key ongoing costs include:Â
- Maintenance and updates: Bug fixes, performance improvements, and feature upgrades Â
- Infrastructure: Node providers, cloud services, and storage as usage grows Â
- Security: Regular audits, monitoring, and protection against vulnerabilities Â
- Transaction fees: Ongoing network or gas fees for processing transactions Â
- Support and operations: Technical monitoring, DevOps, and user support Â
- Compliance: Legal, regulatory, and data protection requirements Â
Costs increase as the system scales, handles more transactions, or requires higher security.Â
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.Â
Typical timeline by complexity:Â
- Simple solutions: 1 to 2 monthsÂ
Basic wallets or simple smart contract apps  - Mid-level projects: 2 to 4 monthsÂ
dApps with integrations and user functionality  - Complex systems: 4 to 9+ monthsÂ
DeFi platforms, marketplaces, or enterprise solutions Â
Blockchain development agencies build products in stages, and each is adding time:Â
- Planning and requirements: 1 to 2 weeks Â
- Architecture and design: 2 to 4 weeks Â
- Development: 1 to 6 months Â
- Testing and QA: 2 to 4 weeks Â
- Deployment: 1 to 2 weeksÂ
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.Â
You can see the main differences in the following table:Â
| 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.Â
Key security practices include:Â
- Smart contract audits: Reviewing code to detect bugs, exploits, and logic flaws before deployment Â
- Secure development practices: Using proven frameworks, code standards, and peer reviews Â
- Encryption and key management: Protecting data with cryptography and secure storage of private keys Â
- Testing and simulation: Running stress tests and attack scenarios to identify weaknesses Â
- Access control: Limiting permissions and enforcing authentication for users and systems Â
- Ongoing monitoring: Tracking activity, detecting threats, and applying updates or patches quickly Â
Security is built into every stage, not added after deployment.Â
