Web3 Developer — the most accessible blockchain role to enter: its base is ordinary frontend, and a frontend developer can move into Web3 by picking up the blockchain layer; so Junior openings here are more realistic than in smart-contract development. Middle independently builds dapp frontends with wallet integration and smart contracts. Senior designs Web3 application architecture, solves complex UX and blockchain-interaction problems. Career flow: frontend developer → learn the Web3 layer → Web3 Developer → Senior; possible further movement towards smart contracts (becoming Web3 Full-stack or moving to on-chain development) or into Blockchain Engineer.

Top skills: web3, blockchain, defi, ethereum, smart contract. Web3 Developer = frontend developer + Web3 layer. Ordinary frontend — the foundation: JavaScript and TypeScript, React (dominates in Web3 frontend), HTML/CSS, understanding of modern frontend development, application state, working with APIs; without a solid frontend base you can't become a Web3 developer. Web3 libraries: ethers.js, viem (modern library for blockchain interaction), wagmi (a set of React hooks for Web3 — the modern standard for the React + blockchain combo), web3.js. Wallet integration: connecting crypto wallets (MetaMask, WalletConnect and others), wallet authorisation. Smart-contract interaction: call contract functions, read their state, send transactions from the application. Blockchain understanding: at the interaction level — what a transaction is, gas, confirmations, accounts, networks; you don't need to write smart contracts, but you need to understand what you're working with. Blockchain UX: the ability to make a clear interface on top of complex blockchain (display of transaction states, errors, waits) — a known pain point of Web3. English — mandatory. The main point: a Web3 Developer is a strong frontend developer who can connect a web application to the blockchain; a solid frontend plus a confident Web3 layer.

Smart Contracts Developer writes logic on the blockchain (smart contracts in Solidity) — on-chain development, focus on security of code that manages assets (see /research/blockchain/smart-contracts). Web3 Developer builds the client side of a decentralised application — the interface through which the user interacts with those smart contracts; they work with wallets, display on-chain data, send transactions, but don't write smart contracts themselves. Crudely: a smart-contract developer builds the "engine on the blockchain", a Web3 Developer — "the application a person uses". Web3 Developer vs ordinary frontend developer: technically a Web3 Developer is a frontend developer (the same React, JavaScript / TypeScript — see /research/frontend), but with a specialisation: they can connect wallets, work with Web3 libraries, interact with smart contracts, understand the blockchain and Web3 UX specifics. Crudely: an ordinary frontend talks to an ordinary server and API, a Web3 frontend additionally talks to the blockchain and the wallet. On entry difficulty: Web3 Developer — the most accessible blockchain role, because 80% of it is ordinary frontend, and you only need to add the Web3 layer; smart-contract and DeFi development require much more specific and deep preparation. Career flow: ordinary frontend → Web3 Developer — a short and realistic transition; Web3 Developer → smart contracts — the next, harder step.

Dapp (decentralised application) — an application part of whose logic runs on the blockchain via smart contracts. A dapp usually has the same structure as an ordinary web application — a frontend used by a person — but instead of (or alongside) an ordinary server it interacts with the blockchain: reads data from the blockchain, calls smart contracts, sends transactions. A Web3 Developer builds precisely the dapp frontend. Why a crypto wallet is needed: in an ordinary application the user logs in by email/password, and the server stores their data and acts on their behalf. In a dapp it's different: the wallet is both the user's identity and their way of acting on the blockchain. A crypto wallet (MetaMask and others) stores the user's cryptographic keys; through the wallet the user authorises in the dapp (without login/password — "sign in with wallet") and, most importantly, signs transactions — any action changing state on the blockchain (transfer, swap, contract call) the user confirms with their wallet. So wallet integration is the central task of a Web3 Developer: connect the wallet, handle authorisation, sensibly walk the user through signing transactions. UX complexity: for an ordinary user wallets, transactions, gas, confirmations, errors — are unfamiliar and intimidating; making all this clear is a large and important part of a Web3 developer's work, and it's a known weak spot of Web3 applications.

A Web3 Developer builds the client side of a decentralised application. 1) Dapp frontend — development of the user interface, as in ordinary frontend development (most often React): screens, components, state, navigation. 2) Wallet integration — connect crypto wallets (MetaMask, WalletConnect and others) to the app, implement "sign in with wallet", handle account and network changes. 3) Smart-contract interaction — via Web3 libraries (ethers.js / viem / wagmi) call smart-contract functions, read their state, display on-chain data in the interface. 4) Transaction handling — walk the user through sending a transaction: show what to confirm, wait for network confirmation, display the status (in progress / success / error) — and do it clearly. 5) On-chain data display — balances, NFTs, history, protocol state — fetch from the blockchain and present nicely. 6) Web3 UX — figure out how to make complex blockchain things (gas, networks, confirmations, errors) understandable to an ordinary person — one of the main and hard tasks. 7) Testing, debugging — including on testnets. Key: Web3 Developer is the "face" of the dapp for the user; smart contracts and infrastructure are useless without an application a person can use them through, and that application is built by the Web3 developer.

Yes, it's the norm: 62% of jobs are remote. Web3, like all of blockchain, is a global, distributed, fully remote industry; Web3 projects are international. For Web3 developers in CIS this is largely the only format: crypto in Russia is regulated, work is mostly on international projects on full-remote, at world rates, English mandatory. The remote-global format is a big plus. And, as for Blockchain Engineer, a Web3 Developer has built-in "insurance" against crypto-market volatility: their frontend base easily converts back to ordinary frontend development — in a crypto downturn you can return to ordinary frontend without losing the profession.

Web3 Developer — the most accessible blockchain role to enter, and the path is shorter than into smart contracts. Roadmap: 1) First — become a frontend developer: this is the foundation of the role. JavaScript / TypeScript, React, HTML/CSS, modern frontend development — without a solid frontend base you can't become a Web3 developer (see /research/frontend). This is 70-80% of the profession. 2) Get the basics of blockchain — how blockchains, transactions, gas, accounts, wallets work, what smart contracts and dapps are; at the level of understanding, without writing contracts. 3) Master Web3 libraries — ethers.js, then modern viem and wagmi (the React + blockchain combo — the current standard); learn to read data from the blockchain and send transactions from the application. 4) Wallet integration — connecting MetaMask, WalletConnect, "sign in with wallet". 5) Smart-contract interaction — call ready contracts from the frontend. 6) Web3 UX — learn to make a clear interface on top of complex blockchain. 7) English — mandatory. 8) Pet project — build a simple dapp (frontend + wallet connection + interaction with a contract on a testnet); this is the best portfolio. 9) Hackathons — Web3 hackathons teach and add to the portfolio. Realistic caveat: entry into Web3 via frontend is realistic; and the frontend base is good insurance: if the crypto segment sags, you remain in demand as a frontend developer.

29 active open Web3 Developer positions in the Zorky CRM sample — a narrow segment. The real picture: Web3 development is a global distributed market not anchored to CIS; the number of openings swings with the crypto-market phase. The role is called variously — "Web3 developer", "Web3 frontend developer", "dapp developer", part of it goes as "frontend developer" on a blockchain project. For Russian-speaking developers a noticeable segment is the TON ecosystem (Telegram apps and games, a boom 2024–2026). Geography: Russia / remote / global. Sources: specialised Web3 and crypto job boards, LinkedIn, Telegram communities for blockchain and TON, hh.ru, Habr Career. For Russian-speaking developers — almost always international projects on remote (crypto is regulated in Russia). NB: the Blockchain direction has had difficulties with auto-classification, Web3 frontend is often counted as frontend — the visible number may understate the market.

A Senior Web3 Developer designs the client side of complex decentralised applications. Frontend at expert level: deep mastery of JavaScript / TypeScript, React, modern frontend architecture, performance, application state — this is the foundation, and a Senior Web3 Developer is first and foremost a strong frontend engineer (see /research/frontend). Web3 layer at expert level: deep mastery of Web3 libraries (ethers.js, viem, wagmi), wallet integration, smart-contract interaction; understanding the subtleties of working with the blockchain from the application. Web3 application architecture: designing the dapp structure — how to organise interaction with the blockchain, on-chain data caching, state management, working with multiple networks. Web3 UX mastery: making the complex simple — turning tangled blockchain interactions (gas, signatures, confirmations, errors, network switches) into a clear, reliable user experience; this is one of the main and underestimated problems of Web3, and a strong Senior can solve it. Reliability: sensibly handling transaction failures, network instability, wallet errors. Blockchain understanding: deep enough to make correct architectural decisions and, if needed, understand the smart contracts the application works with. Client-side security: phishing, safe handling of the wallet and signatures. English — mandatory. For Lead — technical leadership. The main value of a Senior — combine strong frontend engineering with a deep Web3 layer and build a dapp that's convenient and safe for an ordinary person to use.
