Smart contracts are the heart of any blockchain-based application or ecosystem. They’ve come to be known as the backbone of automation in the entire blockchain development process.

When implemented by experts, smart contracts (and blockchain as a whole) promise an impressive package of positive outcomes:

  • automation of processes, transactions, and agreements
  • elimination of confusing and non-reliable paperwork
  • less bureaucracy
  • next-level visibility and security
If you’re looking for a technology partner to help you make the most of blockchain and smart contracts, consider Unicsoft. We have 15+ years of software development experience and 6+ years in blockchain development.

Develop Smart Contracts with Unicsoft to Automate Business Processes & Increase Transaction Trust

Despite its growing popularity, smart contract development still remains a mystery to many organizations and developers, largely due to the nature and features of smart contracts.

Change Intolerance
Change Intolerance
Smart contracts automate transactions, agreements, and operations that follow them by “programming the rules of consensus”. However, due to their immutable nature, smart contracts must be carefully designed to be future-proof. Smart contract changes are time-consuming and expensive.
Legal Regulation of Smart Contracts
Legal Regulation of Smart Contracts
Complying with mandatory regulations is a challenge for smart contract developers. The more complex the legal framework, the more difficult it is to develop code that incorporates its rules.
Code Security
Code Security
Smart contract vulnerabilities often caused by programming errors, protocol bugs, different attacks, etc. can result in significant losses. Smart contract security and risk mitigation must be taken seriously.
Non-tech vs Tech Parties
Non-tech vs Tech Parties
Translating business rules into smart contract code requires deep involvement of both the technical and non-technical parties to ensure the code works as intended and delivers the intended functionality.
Off-chain Data Retrieval
Off-chain Data Retrieval
When smart contracts require data from off-chain resources (that needs to be “pushed” to them), synchronization issues might occur. Addressing such issues (for example, with the use of “oracles”) requires close attention and expertise.
Performance and Scalability
Performance and Scalability
Smart contracts often cause network congestion, increased transaction fees, and more time to process transactions due to their processing speed. Optimization and smart use of consensus mechanisms are crucial to overall performance.
Consensus Mechanisms
Consensus Mechanisms
Consensus algorithms provide security, scalability, and decentralization across blockchain networks. These algorithms include Proof-of-Work (PoW), Proof-of-Stake (PoS), etc. However, they all waste resources. As such, many organizations are moving to new consensus mechanisms such as Proof of Activity (PoA) or Delegated Proof of Stake (DPoS), which promise lower transaction fees and lower energy costs.
Smart contracts vs traditional backend
Smart contracts vs traditional backend
In the case of blockchain applications, the backend is built using smart contracts. For the application not to be resource-greedy, blockchain should not be used for heavy computation. Heavy computation can still be relegated to centralized servers while maintaining the decentralization of the overall application.
Unicsoft has a team of experts that can implement the perfect combination of the above factors, along with your case-specific ones, to develop smart contracts that deliver the promised positive outcomes while avoiding common pitfalls.

Smart Contract Development Services

Smart Contract Architecture Design
Smart Contract Architecture Design
In close collaboration with key stakeholders, we develop the principles of error-free workflows and a functional description of smart contracts. Then we create the architecture using the best practices and latest innovations.
Smart Contract Development
Smart Contract Development
Our team of developers helps organizations develop smart contracts using top-notch practices and tools. The result is thoughtful, balanced, thoroughly tested, and future-proof smart contracts.
Smart Contract Audit
Smart Contract Audit
We leverage our blockchain and smart contract development expertise to help you reassess your smart contracts and eliminate errors.
Smart Contract Optimization
Smart Contract Optimization
Our team identifies specific vulnerabilities and costly models and suggests solutions to optimize and improve the efficiency of smart contracts. We eliminate unreachable or dead code, optimize the loop, implement generic improvements like short-circuiting, fixed-size byte arrays, etc.
Smart Contract Management
Smart Contract Management
We help our clients not only create, but also manage the entire digital lifecycle of a contract, from negotiations to monitoring and verifying compliance with contractual obligations. Our contract management services provide the foundation for trust. In addition, all documents related to the contract are kept in a secure and encrypted form.
Smart Contract Integration
Smart Contract Integration
We integrate smart contracts with external systems and devices to automatically validate and execute transactions. We use Smart Contract Description Language (SCDL) to describe the external interfaces of smart contracts, a Smart Contract Locator (SCL) to find contracts deployed inside blockchain networks, and a Smart Contract Call Protocol (SCIP) to interact with them outside of blockchain networks.
