Tallium Reviews & Testimonials
Paul Dziama
CEO at See The Balance
5.0★
Mobile App Development Review from Paul Dziama
We collaborated with Tallium over a long period of time on multiple digital product projects. Our work included UI/UX design, interface animations, motion systems, and advertising visuals, with direct collaboration between our team and Talliums developers.
A key focus was ensuring that all design and animation assets were not only visually strong, but also technically ready for smooth integration into real products. This required close coordination, clear technical communication, and a shared understanding of both design and development constraints.
Despite working with many partners throughout the year, Tallium became our strongest and most reliable collaboration. Their team demonstrated sharp professionalism, strong ownership, and a deep understanding of how to build and ship high-quality digital products.

We’ve been checking in with Tallium Inc. on this project, and honestly, they keep things on track better than I expected. They set clear goals early on and actually stick to them, which is kinda rare. We already have a significant number of platform users, and so far, it’s looking pretty promising.

Kinjal Gohil's Review Sourced from Google
My interview experience very worst with this company. I faced the same what reviewer post in their previous reviews. HR round is good. She is very humble and very good. But technical round taken by interviewer, I am not sure he really has technical knowledge or not. Though I given all the correct answers he rejected me without giving any genuine reason for rejection. He asked many basic questions of course on my 9 years of experience I know the answers but at last he asked my Expected CTC which is not generally asked in technical round.
As per my knowledge they don't have budget or they already decided to not to select because in interview round asked hardly asked 5-6 questions and based on that given their judgment though given answers correct.

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.
