FAQ: Cold Wallet Essentials

A: No. Check the wallet's official supported assets list—for example, Trezor doesn’t support Solana, but Ledger does.
Q2: Are paper wallets still safe?
A: Yes, if generated offline and stored physically. However, hardware wallets offer better usability.
Q3: What happens if my cold wallet is damaged?
A: Use your recovery seed phrase (24 words) to restore funds on a compatible wallet.
