The team at BLL went above and beyond. They took my app idea and designed/developed it with lots of thought and care. The planning and "sprints" were well organized and we kept on-target with frequent catch-ups & project management tools. Looking forward to launching the app to the public with their support.

Tech Alchemy is building KTO’s centralized exchange and, so far, it’s been quite pleasant with the UI, visuals, and functionality. Can’t wait for the beta test to test what they’ve been working hard on for months!

Based on the experience I had: poor communication and customer service. Don’t seem keen to take on a challenge and take a long time to respond. I was surprised by this after reading other good reviews for this company.

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?
Simple solutions: 1 to 2 months Basic wallets or simple smart contract apps Â
Mid-level projects: 2 to 4 months dApps with integrations and user functionality Â
Complex systems: 4 to 9+ months 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

Anyone can join
Permission required
Control

Controlled by one entity or group

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
