Head of Business Development at KeenEthics

Chatbot Solution Review from Daria Hlavcheva
KeenEthics onboarded Lionwood Software to develop an AI-powered chatbot that could analyze photos of vehicle damage and provide an estimated repair cost for insurance company. The project focused on applying AI to a traditionally manual part of the insurance claims process. The solution needed to interpret car damage from uploaded images, identify relevant damage, and translate the analysis into a cost estimate that could support faster and more consistent claims assessment. Lionwood Software took ownership of the AI development and worked closely with the KeenEthics team to align the solution with the product requirements and insurance use case. Their team demonstrated a strong understanding of both the technical challenges of image-based damage assessment and the business logic behind insurance claims. They were proactive in discussing requirements, clarifying edge cases, and addressing dependencies throughout the development process. The resulting solution helped automate an important part of the vehicle damage assessment workflow, reducing the need for purely manual evaluation and creating a foundation for faster claims processing. Lionwood Software proved to be a reliable technology partner with the expertise to work on AI-driven products where technical implementation needs to be closely aligned with real-world business requirements.

Mobile App Development Review from Nemanja Sindjelic
My project idea was to create a non custodial mobile crypto wallet that allows users to manage their assets across multiple blockchains, including Bitcoin, Ethereum, Polygon, and Solana. The wallet app had to provide an intuitive and seamless experience for both beginners and advanced users, ensuring secure transactions and real-time updates. And ND Labs did it great!
A white label solution by ND Labs offers a minimalistic UI, multi-network support, and advanced transaction fee optimization while maintaining high security standards with biometric authentication and seed phrase protection.
Additionally the wallet well addresses the common challenges in the crypto space: high transaction fees, security risks, and complex user experience. The wallet simplifies crypto asset management and provides automated gas fee calculations, real-time balance updates, and push notifications for transactions.
My opinion is that these guys are really professional. I definitely recommend working with ND Labs (Poland) to anyone who is looking for a white label solution for their crypto wallets.

Working with ND Labs has been an outstanding experience. They demonstrated exceptional expertise in both AI and blockchain technologies. We engaged ND Labs for two complex projects an AI-driven coaching platform and a cryptocurrency platform and they delivered beyond our expectations on both fronts. The teams deep understanding of artificial intelligence and blockchain was evident from the start, and they were able to anticipate and address challenges swiftly. Their timely delivery, responsiveness, and commitment to quality have made our collaboration smooth and highly productive. Were thrilled with the results and look forward to future projects together.

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

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
