Seed phrase

A seed phrase is the 12–24 words that back up all keys of a wallet; anyone with it controls the funds.

No exchange, including Swap.bz, ever needs it. Any site or “support agent” asking for it is a scam.

On Swap.bz

Swap.bz asks only for a receive address and a refund address.

HD wallet

An HD (hierarchical deterministic) wallet derives unlimited addresses from one seed phrase, so you can use a fresh address per payment.

Phishing (fake exchange sites)

Phishing is impersonating a legitimate service — cloned domain, fake support account — to steal deposits or seed phrases.
