Where should I store a seed phrase?

On paper, two copies, two physical places, offline. Not in photos, cloud notes, password chats or email drafts.

What is the difference between a vault and a work wallet?

The vault holds size and almost never connects to sites. The work wallet holds a small balance for daily connects, mints and tests.

Is SMS 2FA enough for an exchange?

No. Use an authenticator app. SMS can be swapped or phished with the SIM.

When can I start farming airdrops?

After the loop exists: official wallet, paper seed, app 2FA, split vault, successful small round-trip, and you can name the network and gas token.

Wallet, seed, 2FA: the loop that must exist before any farm

2026-09-03 · 7 min

A farm without a vault is a public purse. The first skill in crypto is not “which drop is hot”. It is a loop that survives one phishing tab. PhoebusLab’s crypto track opens with networks and the vault for that reason.

What a working loop contains

Official wallet only: install from the project site, check the URL, disable auto-connect.
Seed offline: paper, two copies, two places. Never a photo, cloud note, Notion or Telegram Saved.
2FA in an authenticator app, not SMS. Exchange password ≠ email password.
Vault versus work wallet. The vault holds size and stays disconnected. The work wallet holds dust for sites and mints.

Why L1, L2 and gas come before the farm

You pay gas in the native coin of the chain you are on. L2 exists to make writes cheaper on top of an L1. Bridges move assets between notebooks — and are a favourite phishing surface. If you cannot name the network and the gas token, you are not ready to sign a mint.

Day-1 artifact

Create the wallet. Record the seed on paper. Turn on app 2FA. Send a test you can afford to lose — around 10 USDT or the equivalent dust — out and back. Until that lands, there is no farm and no “research mint”. Simulate every transaction before you sign.

How farms actually drain people

Fake bridges and first-search extensions.
Connecting the vault “just this once”.
SMS 2FA and seed screenshots.
Signing a pretty site without reading the simulated tx.

The crypto course walks networks, the vault, the exchange loop and only then farm modules. If you still have not picked a niche, read the niche filter first. If you think in “how much can I lose per idea”, the risk-unit note applies here too: dust in the work wallet is your unit.
