Hot vs cold is about whether private keys sit on an internet-connected device—not about which brand is “safer forever.”
Quick answer
A hot wallet (phone app, desktop, browser extension, Telegram mini app) is convenient for sending, swapping, and connecting to dApps. A cold wallet (hardware device, air-gapped setup) keeps signing keys offline for long-term holdings. Most people use both: My Wallet as the daily hot wallet across many networks, plus hardware (for example via Ledger Live) for savings they rarely move.
Definitions
| Hot wallet | Cold wallet | |
|---|---|---|
| Keys | On a connected device / app | Offline on hardware or air-gapped media |
| Speed | Fast for daily txs | Slower; intentional |
| Typical use | Spend, swap, dApps | Store larger balances |
| Main risk class | Phishing, malware, fake apps | Physical loss, supply-chain, user error |
Both can be non-custodial. Cold does not automatically mean custodial, and hot does not automatically mean someone else holds your keys.
Hot wallets in practice
Examples of hot, self-custodial products people compare:
- My Wallet — multichain (17 networks), Telegram-friendly, daily UX
- MetaMask, Rabby — EVM browser flows
- Phantom — Solana-first
- Keeper (formerly Tonkeeper) — TON / Telegram
- Trust Wallet, Coinbase Wallet — mobile multichain / beginner paths
Hot wallets shine when you need to move funds today, preview fees, or open a dApp. They demand the same seed hygiene as any non-custodial tool.
Cold wallets in practice
Hardware wallets (often managed with Ledger Live or similar companion apps) store keys on a device that signs transactions without exposing the seed to your phone’s everyday apps.
Cold storage is for balances you can afford to access slowly. It is not magic: a leaked seed phrase written on paper next to the device is still a leaked seed phrase.
A simple split that works
- Daily / DeFi / Telegram — hot non-custodial wallet (My Wallet for multichain life).
- Long-term stack — hardware cold path; move only what you need back to hot.
- Never keep your only seed backup as a screenshot on the same phone as the hot wallet.

Myths
- “Cold wallets earn yield by themselves.” No—storage is not income.
- “Hot wallets are only for beginners.” Power users live in hot wallets for speed; they size risk carefully.
- “One wallet type is always enough.” Diversifying how you store large amounts is normal.
How My Wallet fits
My Wallet is a hot, non-custodial, multichain wallet: strong for everyday sends, swaps, and multi-network balances—including Telegram. For cold storage of large holdings, pair with a hardware workflow (Ledger Live and supported signing paths) rather than forcing everything into one mode.

FAQ
Is Telegram a hot wallet?
If the mini app or bot can sign with keys on a connected device, treat it as hot. My Wallet’s Telegram access is for convenience, not cold storage.
Can a hot wallet connect to hardware?
Many stacks combine software UX with hardware signing. Check supported flows for your device before moving sizeable funds.
Does cold storage remove phishing risk?
It reduces some malware exposure; it does not stop you from signing a malicious transaction you approved on the companion screen.
Should all USDT sit in cold storage?
Only if you rarely need it. Liquidity needs belong in a hot wallet you trust and backed up correctly.
