Hot Wallet vs Cold Wallet: When to Use Each in 2026

Hot wallets: online, convenient, active

Mobile apps like Metrust are hot wallets — connected to the internet for DeFi, swaps, and daily sends. Secure enclave storage and biometrics mitigate risk for active portfolios.

Cold wallets: offline vaults

Ledger and Trezor keep keys air-gapped. Best for long-term holdings you rarely touch. Many users keep a "spending" hot wallet and a "vault" cold wallet.

The hybrid approach

Use Metrust for DeFi and transfers; move large balances to hardware. Same BIP-39 phrase can seed both if derived carefully — or use separate seeds for compartmentalization.
