Understanding Crypto Wallet as a Service

Crypto wallets are online or offline storage spaces that allow users to send, receive, store, and transact with digital assets, such as cryptocurrencies, stablecoins, tokens, and NFTs.

They can be mobile applications, desktop software, web browser plug-ins, or hardware devices. There are two types of wallets in accessibility and storage location:

• Hot wallets are connected online and used to conduct transfers.
• Cold wallets are offline storage where assets are safely stored.

If you want to create a crypto wallet app, you must also understand the difference between custodial and non-custodial wallets:

• Custodial wallets are controlled by a third party, a wallet provider, who gives users credentials to access and control their funds.
• Non-custodial wallets give users full control over their storage, including managing private and public keys and security settings.

Individuals use DeFi wallets to transact in cryptocurrencies and interact with exchanges and NFT marketplaces, while businesses use them to automate crypto transactions, integrate dApps, and accept Bitcoin payments.

Fast Fact

Despite their outstanding safety, only 10% of users have a cold wallet due to their inconvenience.
