FIELDNOTE 001AN INTRODUCTION TO WEB3 WALLETSEST. FOR THE CURIOUS

01 / The essentials

A wallet is more than
a place to hold assets.

Think of a browser wallet as your personal keyring for web3. It helps you manage access and decide when an app can interact with your address.

01

Your keys stay yours

MetaMask is a self-custody wallet. You control your Secret Recovery Phrase and approve every connection and transaction yourself.

02

A doorway to web3

Connect to decentralized apps, explore onchain experiences, and manage supported tokens from a familiar browser extension.

03

Choose before you approve

Review the site, network, and transaction details before confirming. A moment of attention can make a meaningful difference.

02 / Your first steps

Start simple.
Stay intentional.

You don’t need to know everything about web3 to begin. Make your first steps deliberately, and keep your recovery details private.

01

Get it from the source

Use MetaMask’s official download page and select the extension for your browser. Avoid sponsored lookalikes and third-party download sites.

02

Create or restore safely

Follow the wallet’s setup flow. If you create a wallet, write down your Secret Recovery Phrase offline and keep it private.

03

Connect with care

Visit the decentralized app you trust, connect your wallet, then read each permission and transaction prompt before you approve.

MetaMask will never ask you to share your Secret Recovery Phrase with support.

03 / A few good habits

Keep your keys
out of the conversation.

Your Secret Recovery Phrase is the master key to your wallet. Treat it like a secret, not a password you can reset.

01
✳

Never share your phrase.

No legitimate support agent, website, or giveaway needs it. Anyone who gets it can take control of your wallet.

02

Check the address.

Confirm you’re on the correct site before connecting. Look closely for misspellings and unexpected redirects.

03
↗

Read before you sign.

Slow down on transaction prompts. If you don’t understand a request, cancel and learn more before proceeding.

Questions, meet
clear answers.
