# What is a decentralized wallet

In contrast to a centralized wallet (exchange) where the private key is held by a third-party service provider, the private key of a decentralized wallet is kept by the user, and the assets are stored on the blockchain. The user is the holder of the real digital currency. The wallet is just a tool to help users manage the assets on the chain and read the blockchain data, so it is impossible to control, steal, and transfer your assets. Therefore, decentralized wallets are difficult to be attacked by hackers, and users do not have to worry about self-theft or running away from the wallet service provider, because as long as you keep the private key safe when creating the wallet, your assets are still on the chain, and another wallet can be displayed.

 **Attention**: Once a decentralized wallet is lost or stolen, it cannot be retrieved without a backup private key or mnemonic, so be sure to back up your private key safely and correctly.
