Building Blockchain Infrastructure — from ICO to Ecosystem

Smart Contract Development: Writing and Auditing

  • Writing


    Smart Contract is a distributed code, stored on the blockchain platform (Ethereum, Hyperledger, EOS, NEO). Its functioning needs no middlemen, centralized server or even a cloud involvement. The code is executed automatically inside the Virtual Machine when triggered by the pre-programmed events. Softeq writes all types of Smart Contracts, including Ethereum-based — on Solidity and Serpent.

  • Auditing


    Softeq performs full-scale Pre-Release functional and non-functional testing (including unit tests, security audit, smart contract simulation on the testnet etc.) to make sure there are no flaws, misbehaviors and security holes in the Smart Contract code. Softeq’s QA team can also test your Smart Contracts, written by the in-house developers or a 3rd party company, before you deploy it to the Ethereum network.

Decentralized Apps Development

Decentralized applications, or Dapps, is the next step in the evolution of Smart Contracts. They combine a number of interrelated Smart Contracts, united by the business logic and a frontend. Softeq, as a full-cycle development company, possesses a team of solution architects, backend and frontend developers able to write the Smart Contracts for the Dapp, build up a complete application’s architecture, including communications with the oracles, and create a user-friendly UX/UI design on top of that.

Technical Development for ICO

Blockchain gave birth to a new platform for business projects monetization — Initial Coin Offering (ICO). A successful ICO campaign needs an exclusive business idea, supported by a well-planned marketing strategy, its accurate technical realization and careful pre-release testing.

Softeq doesn’t specialize in ICO marketing. We offer only those services we’re professional in — project’s technical realization and testing. If you have a groundbreaking business idea, know how to promote it properly, but need a team of expert system architects, blockchain developers and testers to perform end-to-end development — Softeq is your vendor of choice.

Blockchain Ecosystem Development

Blockchain ecosystem serves as a supporting structure for the rapidly evolving blockchain industry. While developing an ecosystem app, the main issue is to integrate the blockchain features smoothly into the traditional web, mobile or desktop products. Softeq has a team and a competency to build any ecosystem element from scratch, whether it’s a simple cryptowallet or a sophisticated investment portfolio monitor.

  • Wallet

    A basic ecosystem app intended for storing the private keys securely and trading the cryptocurrencies via multiple accounts.

  • Analytics Tools

    A combination of Business Intelligence and Machine Learning algorithms creates a synergetic analytical system, leveraging huge amounts of data to forecast the cryptocurrency markets trends accurately.

  • Exchange

    Softeq builds secure multiplatform exchanges for both digital and fiat currencies — Bitcoin, Ethereum, Ripple, US dollar, Euro etc.

  • Blockchain browser/Block explorer

    A specialized ecosystem app which allows to navigate the blockchain, check the balances and transactions history, monitor the statistics and search the blockchain for transactions and addresses.

  • Oracles

    Softeq builds secure oracle applications, establishing blockchain-to-web communication, essential for the blockchain. Oracles receive data, necessary to trigger the smart contracts, from trusted real-life sources, cryptographically attest it and provide to the blockchain.

  • Portfolio Monitor

    A one-stop-shop app giving access to all major functionality needed to manage your cryptocurrency portfolio — analyze multiple exchanges and get the most accurate market dynamics, assess and reduce investment risks, receive price alerts and make trades just in time, review the latest industry news etc.

  • Hardware devices (wallets, oracles)

    Softeq’s expertise in the hardware design, Internet of Things (IoT) services and all types of communication technologies, such as USB, Bluetooth, NFC, RFID, Wi-FI, allows us to build secure devices, such as hardware cryptocurrency wallets, guaranteeing you secure access to private keys even on a compromised computer, or hardware oracles, acquiring information for smart contracts directly from the physical world.
