Crypto Wallet Types Explained

Hot, cold, custodial, multi-sig: which wallet matches your risk tolerance?

Owning crypto means managing keys. The wallet you choose determines how secure those keys are and who actually controls them.

Custodial vs Non-Custodial

  • Custodial — exchange holds your keys (Coinbase, Binance). Convenient, recoverable, but you do not own the coins; the exchange owes them to you.
  • Non-custodial — you hold the keys. Full control, full responsibility.
The crypto saying "not your keys, not your coins" is the difference.

Hot Wallets

Software wallets connected to the internet. Examples: MetaMask, Phantom, Rabby, Trust Wallet.

Pros: Easy daily use, integrates with dApps. Cons: Vulnerable to phishing, malware, browser extension attacks.

Use only for amounts you would carry as cash.

Cold Wallets

Hardware devices that sign transactions offline. Ledger, Trezor, Keystone, Coldcard.

Pros: Keys never touch an internet-connected device. Cons: Cost ($60-200), small learning curve.

For significant holdings (over a few months' income), cold storage is appropriate.

Multisig

Requires multiple signatures to move funds. 2-of-3 is common.

`` Key 1 — your phone Key 2 — hardware wallet at home Key 3 — hardware wallet in safety deposit box ``

Tools: Casa, Unchained, Gnosis Safe.

Seed Phrase Security

The seed phrase (12-24 words) IS the wallet. Anyone with the phrase has the funds.

  • Never store digitally (cloud backups, photos, password managers)
  • Engrave on stainless steel for fire/water resistance
  • Never type it into any web form ever
