What is a crypto wallet and how to keep it safe
Updated: 2026-10-07 · MarketRadar Whale
A crypto wallet is an app that holds the key to your assets. If you hold the key, it is non-custodial.
The seed phrase
A list of words that rebuilds your wallet. Anyone who has it owns the assets. Never share it and never photograph it.
Safety rules
- Keep the phrase on paper in a safe place.
- No site or support agent ever needs it; anyone asking is a scammer.
- Use a hardware wallet for large amounts.
Your wallet and whale tracking
Your wallet has nothing to do with our tracker; we never ask for your key. Tracking needs only a public address.
