03 · THE JOURNEY

What we're covering here

A beginner-to-intermediate path through Web3 development, all on test networks. I learn it, build it, and teach it as I go.

  1. 01

    Blockchain basics

    What a blockchain really is, with a tiny one you build yourself.

  2. 02

    Wallets + staying safe

    Keys, seed phrases, and the habits that stop you getting drained.

  3. 03

    How memecoins really work

    Liquidity pools, bonding curves and price impact, on testnet.

  4. 04

    Spotting rugs + risks

    How scams are built, so you can recognise them.

  5. 05

    Building + shipping projects

    Tokens, trackers and dashboards you can put in a portfolio.
