Frequently Asked Questions
What is a private key?
A private key is a secret number that proves ownership of blockchain funds. It is used to sign transactions and must be kept secure. Anyone with your private key can spend your funds.
What is a public key?
A public key is derived from your private key using elliptic curve cryptography. It can be shared publicly and is used to verify your digital signatures.
What is a seed phrase?
A seed phrase (or mnemonic phrase) is a human-readable representation of your wallet's master private key. It typically consists of 12 or 24 words and can be used to restore your wallet.
What is an HD wallet?
An HD (Hierarchical Deterministic) wallet generates all keys from a single seed. This means you only need to back up your seed phrase once to recover all your addresses and funds.
