Pure Wallet
Step into a new era of cryptocurrency security and convenience with PureWallet, the groundbreaking duality wallet that combines the best of both worlds with built-in cold storage. Harnessing the power of cutting-edge technology, PureWallet brings together the convenience of a hot wallet with the unmatched security of built-in cold storage. Say goodbye to the hassle of separate hardware devices or the constant fear of online vulnerabilities.
Pure Wallet, a double cover wallet
This work proposes an electronic payment architecture named Pure Wallet(PW), which extends the concept of Blockchain cryptocurrency for offline transactions. The process is divided into three steps. The first step requires the use of an Internet connection, to convert cryptocurrency into a token at the tokenmanager. The token manager initiates a transaction that requires the offline recipient to sign the transaction. These transactions are performed between electronic devices like mobile phones through a secure P2P (Peer communication) NFC(P)) using technologies along the token in the sender's device. The financial value in the form of a token is encrypted by the sender and sent to the receiver's device. In the third step, the receiver converts the received token into cryptocurrency in the presence of an Internet connection by sending the information required to complete the transaction to the token manager. The goal is to propose an electronic payment architecture utilizing Blockchain, which will enable financial transactions without instant connection to the Internet. The Blockchain implementation in this work utilized an EVM-compatible smart contract. The result shows a successful transfer of value without an instant Internet connection.
Offline Tokenization Algorithm
The fundamental idea is to use tokens to create access rights for a specified amount of cryptocurrency. After generating these tokens, they can be exchanged off-chain, which is useful in a situation where internet connections are unreliable. Later, the generated token can be accessed when the internet is available, and the corresponding cryptocurrency can be retrieved through a conversion process. The transaction process must facilitate the offline environments without internet connection. The fact that the offline environment. The tokens are validated using their secondary and tertiary hash values to prevent malicious attacks. These hash values must match the predetermined values that allow the token to be redeemed for actual cryptocurrency. This validation process ensures that only the rightful owner of the token can exchange it for the cryptocurrency.
SWAP (Cryptocurrency Exchange)
SWAP is implemented by accessing the smart contract of each blockchain-based exchange (DEX) post, such as Uniswap and PancakeSwap, through the World Client. After initiating a SWAP transaction, its progress can be tracked using the transaction hash (Tx hash). With that Tx hash, users can monitor the transaction's processing status and the details of its illumination on the scan page of the relevant blockchain network.
Transfer of Asset Rights
The transfer of ownership rights can be implemented offline, eliminating the need for an internet connection. This technology greatly improves transaction speeds and reduces costs associated with exchanging cryptocurrency in the current blockchain environment. To ensure that the receiver has full control over the tokens, the token information must be transmitted to those devices but not held by the sender. To achieve this a 3 + 1 Stablecoin-based technology is implemented, which ensures that the token information is transferred securely to the receiver.
User Interface
The User Interface was designed to check the generated tokens, send each token, or return it to cryptocurrency, and allow it to be delivered through QR code on devices that cannot transmit electronic signals in the future, we plan to improve the compatibility of multiple accounts, other network tokens, and multiple tokens.
Future Plan
In the future, we plan to continue to expand compatibility with blockchains in multiple networks, and we will improve the portion where the current token is fixed to the smartcard at the time of creating it difficult to respond immediately and electronically able to develop a real-time electronic payment solution. In addition, Pure Wallet aims to cooperate with crypto apps in real-time and connect to other clients by attaching a QR code based on the Pianos technology. In The future, the most effective crypto cryptocurrency that deals to converting other crypto platforms in this world.
Solutions such as Pure team, a decentralized network platform that instantly executes the exchange of cryptocurrency. The Pure team intends to lead the field of self-verity supply-consumption in the digital industry as this program is will propose a translation protection and commercial services in combination with its own blockchain network Pure Chain and all embed in services that process transactions in both ways.
