How PureWallet Prevents Double-Spending Offline
Double-spending is one of the biggest risks in offline payments. PureWallet solves it using Offline Tokens, patented PoA2 transfer tech, and on-chain settlement validation.
How it works:
1. Funds are locked
Crypto is converted into Offline Tokens, while the original on-chain balance is reserved so it canโt be spent twice.
2. Secure offline transfer
Tokens are sent instantly via QR, Bluetooth, NFC, or local Wi-Fi using PureWalletโs patented 3-Handshake Protocol, ensuring a secure all-or-nothing transfer.
3. Unique token validation
Each token has a unique cryptographic ID. Once sent, itโs marked as spent and becomes valid only for the recipient.
4. Blockchain settlement
When back online, the token is verified by the smart contract. If already redeemed, itโs instantly rejected.
Why it works:
Offline cryptographic verification blockchain settlement = fast, feeless payments with built-in double-spend protection.
