Blockchain has moved past the hype cycle. Today, companies use distributed ledgers where they create measurable value: shared records between parties that do not fully trust each other, programmable digital assets, transparent audit trails, and faster settlement. Plavno delivers blockchain development services for fintech companies, investment platforms, marketplaces, and enterprises that need production-grade systems rather than proofs of concept.
Our team combines blockchain engineering with custom software development, web development, and mobile development, so smart contracts, backend services, and user interfaces are designed as one product.
Smart Contract Development and Security
Smart contracts are immutable once deployed, which makes engineering discipline critical. We define business logic and edge cases up front, write comprehensive automated tests, apply proven access-control and upgradeability patterns, and prepare contracts for independent audits. Supporting infrastructure — nodes, APIs, key management, and wallets — is validated through cybersecurity and penetration testing.
Asset Tokenization and Digital Investment Platforms
Tokenization turns real-world assets — real estate, funds, receivables, or intellectual property — into digital tokens that are easier to issue, divide, and transfer. We develop issuance, investor onboarding, cap-table and transfer logic, and reporting, as in the T-Rize real estate investment platform. For business use cases of digital tokens, see our article on leveraging NFTs to grow and fund your business.
DeFi Development
Decentralized finance products such as lending pools, staking, and liquidity protocols require careful economic design as well as secure code. Our guide on how to build a successful DeFi lending platform covers the key architecture and compliance considerations, including KYC/AML procedures where regulation requires them.
AI and Blockchain: On-Chain Analytics and Intelligent Automation
AI makes blockchain data usable. We build on-chain analytics, wallet and transaction risk scoring, and anomaly detection based on the same techniques we used in our AI-powered fraud detection system. As AI agents begin to transact on behalf of users, verification and payment authorization become critical — read more about trust and verification in agent-to-business transactions.
When Blockchain Is — and Is Not — the Right Choice
Not every problem needs a blockchain. During discovery we assess whether a distributed ledger adds real value compared with a conventional database, which network fits your requirements, and how regulatory constraints affect the design. Software development consulting and AI consulting help you make that decision before investing in development.
