Our services

At Smartym Pro, we provide technical and business-related assistance on any aspects of blockchain implementation. Regardless of the project stage you need help with, we’re ready to share our expertise and improve your business operations.

  • Consulting

    If you want to implement a blockchain solution in your business, we can consult you before the start of the development. We will research your case and conclude on whether blockchain is really needed, if not - we will suggest better options.

  • PoC

    We always recommend our clients to start the project's realization with a Proof of Concept. Our blockchain consultants and certified developers can help to check the viability of your idea without spending too much of your budget.

  • Blockchain development

    Using a set of professional blockchain technologies and tools, our expert team will create a future-proof solution that will cover the business needs, ensuring data security, detailed documentation, smooth user experience and further maintenance.

  • External audit

    An in-depth audit of your blockchain system (specification compliance check, automated and manual vulnerability check, сode architecture analysis, etc) and a detailed report on the weaknesses as well as recommendations on how to remove them.

Our Expertise

  • Private Blockchain

    Create a private secure network with quick transactions working via confidential consenus algorithms.

    • Hyperledger

      Hyperledger Fabric can guarantee higher security and transparency within your business processes. It’s a full-fledged permissioned system that enables to choose who can access the blockchain and what information they can access, which is incredibly important for enterprise solutions.

      Nevertheless, we can select different Hyperledger frameworks depending on your business goals, expected network complexity and types of transactions.

      • Highly modular and configurable architecture
      • Permissioned membership
      • Supports multiple programming languages
      • Transparency and security of transactions

    • Corda

      Corda is a great business blockchain platform built by R3 Consortium. Used for building applications for financial companies, it is a permissioned network. Corda is helpful in removing costly friction in business transactions to allow businesses to transact directly.

      With Corda we can develop numerous so-called CorDapps for both private and public networks, create a custom token economy and integrate smart contracts.

      • Encrypted data transaction
      • Point-to-point architecture
      • Highly scalable and agile, all versions are interoperable
      • Multilateral ledger - network participants have copies of only those transactions that they are involved in

  • Public Blockchain

    Decrease the vulnerability of your data and financial information to hacking and any other third-party alterations.

    • Ethereum

      Ethereum is a global distributed blockchain software platform for developing Smart Contracts and Decentralized Applications. The possible spheres of application for Ethereum are endless. It offers complete security, diminishes the risk of fraud and hacking and faster transaction execution time.

      Smartym Pro is able to provide Ethereum-based solutions for businesses across the globe, both financial and non-financial and ensure secure crypto payments with Ethereum’s currency ETH.

      • Reliable Smart Contracts
      • Large community with ready libraries and tools
      • Marketplaces for Dapps
      • Easy to support due to high popularity of platform

    • Solana

      Solana is a high-throughput layer-1 blockchain. It combines Proof of History, a cryptographic clock that orders transactions, with Proof of Stake consensus. Low transaction fees make it a common choice for payments, token-based products and applications with many small transactions.

      We can design, build and audit Solana programs in Rust with the Anchor framework, issue and integrate SPL tokens, and connect on-chain logic with your backend and wallets.

      • High throughput and low transaction fees
      • Proof of History combined with Proof of Stake
      • Programs written in Rust with the Anchor framework
      • SPL tokens for payments and digital assets

  • Other technologies

    We help our partners choose the blockchain technology that fits their case, from permissioned networks on Hyperledger and Corda to public networks on Solana and Ethereum, and connect it with the rest of their systems.

Frequently Asked Questions

Often a database is enough. A blockchain earns its cost when several organisations that do not fully trust each other need to share and update the same records and none of them should own the only copy, or when outside parties must be able to verify a tamper-evident history. If one company controls both the data and the users, a well-designed database with access control and audit logging is usually cheaper, faster and easier to change. We check this at the consulting stage and tell you if blockchain is not the right fit. In that case we can build the system as custom software instead.

It depends on who must see the data and who runs the network. Private (permissioned) networks such as Hyperledger Fabric or Corda suit consortiums and regulated processes, where members are known, access is controlled and business data stays confidential. Corda shares each transaction only with the parties involved, which is why it is common in financial workflows. A public network such as Ethereum suits cases where anyone should be able to verify records or hold tokens, at the cost of transaction fees and publicly visible data. Solana is an alternative public network when low fees and high throughput matter, for example in payments and token-based products. Hybrid designs, with business data on a private network and proofs anchored on a public one, are also common. Our overview of blockchain trends for 2026 compares Hyperledger and Corda in more detail.

A PoC answers one question. Can your business process work on a blockchain with the participants, data and rules you have? It usually covers mapping the process to smart contract logic, a first network architecture with deployment options, a working prototype of the key transactions and a list of what a production version will need. The timeline depends on how many organisations and roles take part, how complex the business rules are, which existing systems the prototype has to talk to, and how quickly your team can make decisions and give access to data. We agree the scope and success criteria before the PoC starts.

Yes. An external audit includes a check against the specification, automated and manual vulnerability analysis and a review of the code architecture. You receive a report that lists the weaknesses we found, explains their impact and recommends how to fix them. If you wish, the same team can then fix the issues or take over further development. An audit lowers risk but cannot prove that code is free of defects, so for contracts that hold significant value we also recommend thorough testing and monitoring after release.

Yes, and in most enterprise projects integration takes more effort than the smart contracts themselves. The ledger usually stores only what the parties need to share and verify, while everything else stays in your existing systems, connected through APIs and event handlers. In a blockchain-enabled document flow project, for example, the client already ran a 1C-based system, and we moved its business processes to Hyperledger Fabric step by step. Backend and integration work around the ledger is done by our Java and enterprise backend engineers.

As a whole-system question, not only a smart contract one. We look at access rights and identity management on permissioned networks, key and wallet management, code reviews and tests for smart contracts, protection of the APIs and off-chain services around the ledger, and the handling of personal data, since data written to a ledger is hard to change or delete later. Our development processes are ISO 27001 certified.

Mostly scope and the network model. The number of participants and roles, the complexity of the smart contract logic, whether you need a private network with its own infrastructure or deploy to a public chain, integrations with existing systems, wallets or payment flows, security and audit requirements, and who will run and support the network after launch decide most of the effort. Starting with a PoC keeps the first investment small and gives a reliable basis for estimating the production version.
