We implement hierarchical deterministic key derivation (BIP-32, BIP-44), optimize gas with EIP-1559 and transaction batching, and integrate Layer 2 scaling. Our lightweight libraries ensure fast sync with full validation, with optional EIP-4337 smart contract wallets for automation and security.

Ethereum Token Development

Whether you need an ERC-20 token, an ERC-223 token, or a token of another type, our Ethereum developers can design any custom digital asset. We offer security tokens, utility tokens, asset-backed tokens, and other solutions, all created with robust security features to ensure safe transactions and accurate record-keeping. Our solutions ensure gas efficiency, compliance with industry standards, and seamless integration with DeFi ecosystems.

Benefits of Ethereum Application Development

Rich Ecosystem

Ethereum is one of the most popular blockchains boasting a mature ecosystem with thousands of dApps. This ecosystem continues to expand with various Layer 2 solutions, improving scalability and making development cheaper. Thus, investing in Ethereum app development services provides a forward-looking, scalable solution that adapts to evolving technologies.

Flexible Development

Another crucial benefit of Ethereum application development is flexibility. This blockchain platform offers an open-source ecosystem, fully customizable smart contracts, and a wide range of Web3 development tools (Solidity, Hardhat, OpenZeppelin, Web3.js, etc.). With Ethereum, you can develop virtually any blockchain solution, whatever your use case may be.

Private Networks

With Ethereum app development, you can set up private networks using tools like Hyperledger Besu, Quorum, and others. A private network allows you to store sensitive data securely while having full access to Ethereum’s smart contract functionality. Additionally, it can be customized and optimized to meet various business needs and use cases.

Ethereum Development Bottlenecks We Tackle

High gas costs limit contract usability — we write efficient smart contract logic and use tools like the Solidity optimizer and custom assembly where necessary.
Network congestion slows dApps — we support L2 integrations like Optimism and zkSync for faster and cheaper transactions.
Security issues lead to exploits — we use battle-tested design patterns, thorough audits, and formal verification tools.
On-chain storage is expensive — we minimize state changes and offload large data to decentralized storage like IPFS or use Merkle trees.
Fragmented ecosystems hinder composability — we leverage bridges and cross-chain messaging protocols like LayerZero or Axelar.
Complex toolchains slow development cycles — we provide streamlined SDKs, prebuilt templates, and dev-friendly tooling.
Hard-to-reproduce errors on mainnet — we use robust local test environments and forking tools like Hardhat + Tenderly for simulation.
Immutable contracts limit evolution — we implement proxy patterns (UUPS/Transparent) for safe, flexible upgrades.
Inconsistent interfaces slow integration — we follow and contribute to ERC standards for smooth composability.
Wallet UX and gas fees confuse users — we offer meta-transactions, gas abstraction, and simplified onboarding flows.

Business Case Analysis

01
We gather your business requirements, create the solution’s concept, and prioritize business objectives. Our developers carefully choose the most suitable technology stack for the project, considering factors like scalability, security, and transaction costs. They map out the architecture, plan the smart contract logic, and perform transaction fee & TCO optimization.
02

Architecture & Design

02
Once the concept is established, we build a GDPR-compliant PoC and showcase use scenarios. We plan for cross-contract communication and make decisions about cloud hosting options to ensure scalability and security. Our focus is on creating a user-centric design, with clickable prototypes that accurately reflect the app’s future look and feel.
03

Smart Contracts

03
In this Ethereum app development phase, Unicsoft’s experts assess the platform specifics and integrate the app with the blockchain, focusing on functionality and business logic. We engineer smart contracts to meet the defined requirements, making sure they are high-performing and scalable. We thoroughly test their functionality to ensure smooth execution on the blockchain.
04

UI/UX Design

04
Our team develops responsive, mobile-adapted user interfaces that seamlessly interact with the blockchain. We create custom-built transaction states guiding the user through the transaction process, from initiating transactions to receiving feedback. The UI is continuously updated with real-time smart contract data so that users stay in sync with the current state of the blockchain.
05

Quality assurance

05
We conduct both manual and automated testing, covering functional, UI, and integration checks, alongside stress testing to verify performance. Additionally, we monitor resource consumption and ensure that the app meets performance SLAs, providing comprehensive software audit reports.
06

dApp Deployment

06
After thoroughly testing the application on a testnet, we deploy it to the mainnet and prepare for its launch on decentralized application stores. Our engineers use real-time usage stats to drive ongoing updates and manage the backlog to continuously improve the dApp. We integrate microservices and smart contracts to keep the infrastructure scalable and adaptable.

FAQ

  • How much do Ethereum development services cost?

    The cost of Ethereum blockchain development services heavily depends on the complexity of your decentralized application. Let’s take smart contracts, for example. They can be relatively simple and cost between $2,000 and $5,000, or complex, with costs ranging from $20,000 to $50,000. Another critical factor is the development team’s expertise and location. Junior Ethereum developers typically cost $20 to $50 per hour, whereas experienced (senior-level) engineers charge $150 - $250 hourly or even more.

    Other factors that influence the cost of Ethereum development services include features and functionality, security audits, and ongoing maintenance and support. To summarize, a simple decentralized app with basic functionality may cost around $20,000 - $50,000, while a complex dApp requires an investment of $150,000 - $200,000 or more.

    If you would like to receive a cost estimate for your Ethereum project, don’t hesitate to contact us and share the details. We will reply within one business day.
  • What engagement models does your Ethereum development company offer?

    You can collaborate with us under one of the three engagement models: end-to-end development, dedicated team, or team augmentation. Let us briefly describe the difference between them.

    End-to-end development—we take full responsibility for your product, developing it from scratch and working closely with stakeholders at every stage of Ethereum app development.

    Dedicated team—we dedicate a team to your project and manage it on your behalf, freeing up your time for core business activities.

    Team augmentation—Unicsoft helps you bridge the talent gaps by integrating our best software developers into your in-house team while enabling you to maintain full control over your project.

    If you would like to receive more information, please contact us via the website form below.
  • Do you offer post-launch maintenance and support?

    Naturally! We utilize monitoring and observability solutions, such as Grafana, Sentry, and New Relic, to continuously monitor your system, proactively address issues, and introduce improvements. Our engineers help you keep your product in top-notch condition at all times, ensuring a consistent, frustration-free, and smooth user experience.

    Note that our team specializes in providing L2 and L3 level support (we do not offer L0 and L1 support). L2 application support deals with complex issues such as software errors, system configuration problems, compatibility issues, and more. L3 support involves dealing with the most challenging errors that require extensive technical knowledge and expertise.

    We can help you with dApp maintenance and support even if your app was developed by a third-party company or some of its documentation is missing.
