Seed Phrase (Recovery Phrase, Mnemonic)

A seed phrase — also called a recovery phrase or mnemonic phrase — is a human-readable list of 12 or 24 words that encodes the master private key for a wallet. The format is standardized by BIP-39 and is used by most modern wallets (MetaMask, Ledger, Trezor, Rabby, Coinbase Wallet, etc.). With the seed phrase, you can restore the wallet — and any assets in it, including tokenized domains — on any compatible device. Without it, lost device access usually means permanently lost funds, because there is no central authority to issue a "password reset." Best practices: write the seed phrase on paper or a metal backup, store at least two copies in separate physical locations, and never type it into any computer, cloud document, password manager that touches the cloud, chat, or AI assistant. See Recovering a Tokenized Domain After Wallet Loss for the full operational guide.
