Seed Walkthrough
Watch raw entropy become a BIP-39 seed phrase, get stretched into a 64-byte seed by PBKDF2, become a BIP-32 master key, and then branch into the standard derivation paths that modern wallets use. Pure browser crypto. Nothing leaves this tab.
⚠ Educational demo
Do NOT use any seed phrase generated here to hold real Bitcoin. The phrase is generated in your browser and never transmitted, but it is also displayed openly on this page. Anyone looking over your shoulder, screen-recording, reading your browser history, or inspecting a cached page can take ownership of every coin derived from it. This tool exists to show you what a seed phrase is — not to be a wallet. For real funds, use a hardware wallet that generates the seed offline.
Why four paths, not one?
A seed phrase alone doesn't say which addresses your coins live at. The same words, recovered into different wallets, can find different balances — because each wallet defaults to a different path and a different address encoding. BIP-44 is the oldest (legacy P2PKH). BIP-49 wraps SegWit in a P2SH shell so it looks like an old "3…" address. BIP-84 is native SegWit, the modern default. BIP-86 is single-key Taproot, the most modern.
If you ever "lose" coins moving between wallets, the seed is almost never the problem — the new wallet just isn't looking at the right branch. Sweep tools that scan all four paths are the canonical fix.
