Compared with centralized wallets (exchanges) whose private keys are in the hands of third-party service providers, the private keys of decentralized wallets are kept by users themselves, assets are stored on the blockchain, and users are the real holders of digital currency However, the wallet is only a tool to help users manage the assets on the chain and read the data of the blockchain, so it is impossible to control, steal and transfer your assets.
Therefore, it is difficult for decentralized wallets to be attacked by hackers, and users do not have to worry about the wallet service provider's self-stealing or running away, because as long as you keep the private key when you create the wallet, your assets are still on the chain. Change wallets can be displayed as well.
Note: Once the decentralized wallet is lost or stolen, it cannot be retrieved without backing up the private key or mnemonic, so be sure to back up your private key safely and correctly.
