Your Wallet & Its Master Seed
Our wallet is built on an HD (or hierarchical deterministic) framework, which is the industry standard for bitcoin address generation and management. Each public address your wallet generates stems from your wallet's xPub (or Extended Public Key). Once your public address receives an incoming payment, a new address will automatically be generated and display when you click on receive.
If you use the same address each time you receive funds, it becomes easy for anyone to track your entire payment history. This method of address generation improves privacy by automatically presenting you with a new address when youre expecting payment.
Advanced Users: Our wallet implements BIP44 to generate accounts and addresses, and the recovery mnemonic/seed implements BIP39. The seed is compatible with other BIP44/BIP39 bitcoin wallets.
