Software Development Review from Anonymous
We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs. Talentica was brought on board to test and refine the concept from both functional and engineering perspectives, and later to build a Minimum Viable Product (MVP) aligned with the agreed specifications and constraints.

Software Development Review from Anonymous
For several years, the team was composed entirely of Talentica contractors. Since January 2022, I have been directly managing them. The Talentica team handled the admin tooling backend, which included multiple Python Flask services with Postgres and Elasticsearch. These services operated in a service-oriented architecture deployed on Kubernetes, using Istio for service mesh and Spinnaker for deployments.

Web Development Review from Raj Sardana
After working with Webisoft for a few months, I'm really pleased with the caliber of support and output I've had. I manage a little business, so I'm highly involved. I am aware that I have managed previous marketing companies a little too poorly in the past. However, Webisoft has shown me a great deal of patience and has taken the time to comprehend my unique demands and create a plan to address them.

Blockchain Review from Trevor Ogata
Our team hired Webisoft to build out our alpha version of our to ticketing platform. Webisoft did an incredible job providing excellent customer service, reliability, communication, and adaptability. Webisoft was recommended by colleagues in the industry and did an incredible job given the difficult time constraints they had to work within. They were a great partner and we hope to work with them more in the future. (Verified via email)
Pixel Guru, a mobile solution, helps dealerships have more online car sales by increasing inventory turnover. It hired Webisoft to develop its iOS & Android applications and the management system. The project was executed using React Native and Django. Webisoft's approach was marked by flexibility, professionalism, and punctuality. The agency's project management style was excellent, equipping Pixel Guru with essential tools and feedback for seamless tracking. (Verified by email)

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

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
Access
Anyone can join
Permission required
Control

Controlled by one entity or group
Transparency

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
