How to become a Blockchain / Web3 Engineer

Build on-chain systems: smart contracts, the cryptography under them, and the security mindset the money demands.

21-30 weeks4 phases14 steps13 free resources2 checkpoint tests

Best for

Engineers who already have some web development behind them and are drawn to systems where mistakes are public, permanent and expensive.

Maybe not for you if

A first path from zero. Prior web development is commonly reported as a strong prerequisite, and the market is volatile - treat it as a specialisation, not a safety net.

The 4 phases

What each phase gets you to. The steps, resources and checkpoint inside each one open with a free account.

  1. Phase 1 - Web, TypeScript and the cryptography underneath

    5-7 weeks

    Goal: Ship a typed, deployed web app that already reads live chain data, because that is what most Web3 products actually are.

    3 steps · ends in a build deliverable · assumes basic programming in any language

  2. Phase 2 - The EVM, Solidity and the Foundry workflow

    6-9 weeks

    Goal: Write, test, deploy and verify a non-trivial contract on a public test network using the toolchain teams actually use.

  3. Phase 3 - Security, integration and a dApp people can use

    6-9 weeks

    Goal: Ship an application a stranger can use, written defensively, with the failure cases written down before the README.

    4 steps · ends in a scored checkpoint (70% to clear)

  4. Phase 4 - Interviews, contests and staying employable either way

    4-6 weeks

    Goal: Keep the general engineering skills that make you hireable in any market, and put your security work somewhere strangers can read it.

What hiring actually looks like here

Web3 hiring is commonly remote-first, which lets Indian engineers access international teams without relocating. Openings are far fewer than mainstream software and the sector is cyclical, so keep general engineering skills current alongside it.
