Related concepts

The vocabulary this page depends on.

  • →Web3 Wallet

    A Web3 wallet stores your keys and signs transactions, letting you hold assets and connect to on-chain applications without an intermediary.

  • →Private Key

    A private key is the secret number that authorises transactions from an address; the public address is derived from it, never the reverse.

  • →Self-Custody

    Self-custody means you control the private keys to your assets, so no company can freeze, lend out or lose them on your behalf.

  • →Seed Phrase

    A seed phrase is the 12–24 word backup from which every private key in a wallet is derived — whoever holds it holds the wallet.
