So I recently joined a session that introduced me to the world of blockchain, Ethereum, and Web3 — and honestly, it was both mind-blowing and exciting.
Before this, I’d heard all the buzzwords: decentralization, smart contracts, wallets... but now it’s all starting to make sense.
What Actually Happened
We started with the basics—what blockchain really is, how Ethereum fits into the picture, and what Web3 is trying to change.
At first, it felt a bit abstract, but the more we explored, the more I saw how it all connects:
- Blockchain isn’t just hype — it's a whole new way of storing and verifying data.
- Ethereum isn’t just a cryptocurrency — it’s a platform for building real apps (but decentralized).
- And Web3? It's about giving people control back.
Then Came MetaMask 🦊
Toward the end of the session, we did something practical: installing MetaMask.
If you’ve never used it, MetaMask is a crypto wallet that lives in your browser. It lets you connect to decentralized apps (dApps) and explore the Web3 world.
Setting it up was straightforward. I downloaded the extension, created a wallet, saved my recovery phrase (very important!), and just like that, I was Web3-ready.
Adding Lisk Networks
Here’s the part that made it all feel real — we connected MetaMask to two Lisk networks:
lisk mainnet
lisk sepolia testnet
first click the link then on the top right you will be able to connect to your meta mask wallet approve the connection.
the next step is searching for the lisk mainnet and lisk sepolia testnet and connect them to the metamask wallet
your wallet should be able to look like this after the connection
- Lisk sepolia Testnet
- Lisk mainnet

Awesome intro and walkthrough!
It’s always exciting to see that moment when Web3 concepts finally click; MetaMask, networks, and how it all ties together. I had a similar experience when I started digging into how decentralized infrastructure could support real-world AI applications.
If you’re curious about where this is all headed, you might enjoy exploring projects that are pushing AI + blockchain further, like running AI models directly on-chain (no external servers!). We’ve been experimenting with that in a network we're building and would love to share thoughts if you're interested!
Great post again and a must-read for anyone starting with Ethereum or Lisk...
thank you for the reply its really encouraging and yes i would like to hear thoughts about what you are building
