Wallet Types

Wallets don't actually store your crypto—they store the private keys that prove you own it. Different wallet types offer different tradeoffs between security and convenience.

Building Your Setup

Most experienced users don't rely on a single wallet. They build a wallet stack that separates daily spending from long-term savings.

🛠️ Build Your Wallet Setup

Answer a few questions to get a personalized recommendation:

Your experience level?
How much are you storing?
Primary use case?
Your Recommended Setup
Primary Wallet
Hot Wallet (MetaMask/Phantom)
Secondary
Consider hardware later

Start with a hot wallet to learn. Upgrade to hardware as holdings grow.

🏗️ Recommended Wallet Architecture

Daily Wallet
  • • Hot wallet (MetaMask, etc.)
  • • Small balance only ($50-200)
  • • For DeFi, NFTs, experiments
  • • OK to connect to new dApps
Vault / Savings
  • • Hardware wallet (Ledger, Trezor)
  • • Main holdings stored here
  • • Connect via WalletConnect
  • • Rarely touches new contracts
Treasury (Optional)
  • • Multi-sig (Safe, Squads)
  • • For team/shared funds
  • • 2-of-3 or 3-of-5 signers
  • • No single point of failure

💡 Pro tip: Transfer from Daily → Vault regularly. If your daily wallet gets drained, you only lose what`'s in it.

Setup and Safety

Your seed phrase is the master key to all your funds. Protecting it is the single most important security practice in crypto.

🔑 Understanding Seed Phrases

A seed phrase (recovery phrase) is 12-24 words that can regenerate your private keys. Anyone with these words controls your funds.

DO
  • ✓ Write on paper, store in safe place
  • ✓ Stamp into metal for fire/water protection
  • ✓ Store copies in separate locations
  • ✓ Consider a bank safe deposit box
DON`'T
  • ✗ Screenshot or photograph it
  • ✗ Save in cloud storage or notes apps
  • ✗ Email it to yourself
  • ✗ Share with anyone, ever

🚨 At Risk
Test Your Recovery!

Before storing significant funds, test recovery with a small amount:

  1. 1. Send a tiny amount ($5) to your new wallet
  2. 2. Delete the wallet app or use a different device
  3. 3. Restore using only your seed phrase
  4. 4. Verify the funds are accessible
Watch Out

Common Mistakes & Gotchas

These mistakes have cost people everything. Don't learn the hard way:

📸
I'll screenshot my seed phrase and save it to iCloud
Write seed phrase on paper or metal. Never store digitally—cloud services get hacked, photos sync automatically.
🎰
I'll approve this contract from my main wallet with all my savings
Use a separate 'burner' wallet for new dApps and experiments. Only keep small amounts there.
🔄
My hardware wallet works fine, I'll skip the firmware update
Firmware updates patch security vulnerabilities. Always update, but verify the update is from the official source.
🎯
I'll use one wallet for everything—experiments, savings, airdrops
Separate wallets by purpose: daily/experiments, main savings, and airdrops. Limits blast radius if one is compromised.

⚠️ Remember: In crypto, YOU are the bank. There's no "forgot password" recovery or customer support to reverse mistakes. Take security seriously from day one.
