What a seed phrase means
A seed phrase, also called a recovery phrase, is the list of words that a wallet gives you when you create it. Ethereum.org's glossary describes it as a list of words given to you when you create a digital wallet. Whoever has the words controls the wallet.
How it works
Most wallets follow the BIP-39 standard. The words come from a fixed list of 2,048, and a phrase has 12, 15, 18, 21 or 24 words. The wallet turns the phrase into a seed, and the seed generates every private key in the wallet. That is why you can import the same phrase into a new app and see all your accounts again.
Example: a Telegram account that says it is a "support agent" for a trading bot tells you your wallet is "out of sync" and links to a form that asks for your 12 words. The form sends them to the scammer, who empties the wallet in one minute. Real support never asks for the phrase.
Why it matters for traders
- One phrase, all funds: keep your main savings in a wallet whose phrase never touches a bot.
- Trading wallets: some bots manage keys for you. Check the export option in each review, for example our GMGN review.
- Scams: fake support, fake airdrops and fake "wallet checkers" all target the phrase. See our rug pull guide and official links.
