Blockchain consulting
and Web3 solutions company

It depends on complexity. An initial assessment with feasibility report can be completed in 2-4 weeks. A functional proof of concept (PoC) takes an additional 4-8 weeks. A complete project — from initial consulting to production-ready product — typically takes between 3 and 6 months. We work in 2-week sprints with incremental deliveries, so you start seeing results from the first month.

Not necessarily. Blockchain adds real value when multiple parties need to share data without a trusted intermediary, when immutable traceability is required, or when the business involves digital value transfer (tokens, crypto payments, tokenized assets). If your problem is better solved with a centralized database, we will tell you. Our initial assessment includes an honest analysis of whether blockchain is the right technology for your specific use case.

We work with 15+ networks depending on project needs. The most common: Ethereum for maximum decentralization and DeFi ecosystem, Polygon for applications needing low cost and high speed, Solana for high throughput (65,000 TPS), Avalanche for custom subnets, and Hyperledger for private corporate networks. Selection depends on factors such as performance requirements, transaction costs, privacy needs and the available integration ecosystem.

The first consultation (30-minute video call with our technical team) is free. From there, costs depend on scope: a feasibility assessment with executive report starts from €3,000, a functional PoC from €8,000, and a full development project is quoted individually based on complexity. We offer fixed-price quotes with no surprises after the assessment phase.

Yes. Our post-launch support includes 24/7 smart contract monitoring, security updates, gas cost optimization, functional evolution and incident support. We also offer monthly maintenance contracts that include development hours for new features. The goal is for your blockchain solution to evolve with your business, not become obsolete.

Yes. Although our headquarters are in Estonia (EU), we work with clients worldwide. We have experience with companies in Spain, the United States, Latin America, Singapore and the Middle East. We work remotely with collaborative tools and adapt to your time zone. Communication is in English, Spanish or Portuguese.

Blockchain is the base technology (distributed ledgers, consensus, immutability), while Web3 encompasses the entire ecosystem built on blockchain: dApps, DeFi, NFTs, DAOs, decentralized identity and metaverse. Our consulting covers both areas. If your project focuses on infrastructure and smart contracts, we are talking about blockchain. If it includes decentralized user experience, tokenomics or governance, we are in Web3 territory. In practice, most modern projects combine both.

Blockchain technology has a steep learning curve and mistakes can be costly and irreversible (immutable contracts, lost funds). A specialized consultancy like Beltsys Labs brings: experience in 300+ real projects, deep knowledge of multiple networks and protocols, ability to evaluate technical and economic feasibility before investing, and a team that has been through the problems your project might face. We save you months of trial and error.
