A Bitcoin wallet is a tool or service designed to securely manage and store bitcoin. While wallets vary in type, they all serve two core purposes:
Storing cryptographic keys:
- A public key (receiving address) enables bitcoin receipts.
- A private key (secure signature) authorizes bitcoin transfers.
- Facilitating transactions: Enabling seamless sending/receiving of bitcoin.
Bitcoin ownership is recorded on the blockchain, not within the wallet itself. Instead, wallets store keys linked to specific bitcoin, granting users control over their funds and transaction history.
Types of Bitcoin Wallets
Bitcoin wallets are categorized by two key factors:
| Criterion | Hot Wallet (Online) | Cold Wallet (Offline) |
|---------------------|-----------------------------------|-----------------------------------|
| Custodial | Managed by third parties (e.g., exchanges) | Custodians like River use offline vaults |
| Non-Custodial | User-controlled keys (higher responsibility) | User-managed, offline (e.g., hardware wallets) |
Hot Wallets
- Always connected to the internet (web, mobile, or desktop apps).
- Ideal for frequent transactions but vulnerable to cyber threats.
- Examples: Exchange accounts, mobile apps like Exodus.

Cold Wallets
- Offline storage (immune to remote hacks).
- Best for long-term holdings; requires physical security.
- Examples: Ledger, Trezor hardware wallets.
Custodial vs. Non-Custodial Wallets
| Feature | Custodial | Non-Custodial |
|--------------------|-----------------------------------|-----------------------------------|
| Control | Third party holds keys | User owns keys |
| Security | Dependent on custodian’s practices | User-responsible |
| Recovery | Account recovery options | Seed phrase backup required |
