# DEX Wallet ![](https://3005308956-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FwuYmF52DEjB3koXIZSLu%2Fuploads%2FFhFot1U1dtR5Ucji64Gz%2F%EB%B0%B1%EC%84%9C5.jpg?alt=media\&token=913655df-2f20-4396-b9fd-2f3b93377916) The evolution of the BerryStore 4.0 platform starts from the Decentralized wallet. Traditional convenience-based CEX wallets had the greatest vulnerability in security. However, Binance Application Sidechain(BAS) based on Binance's Binance Smart Chain (BSC) was able to apply DEX wallet to simultaneously ensuring convenience and security by the decentralized transaction processing of each Dapp. Individual asset management and operations are now guaranteed, enabling more scalable and secure services. Major wallet service functions include BNB coin-based BERRY token asset operation, Mnemonic and private key attachment, smart contract function application, NFT asset storage, and biometric security authentication. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
