BIP32 HD Key Derivation

Paste a hex seed or xprv/tprv plus a BIP32 path to derive the child xprv, xpub, private key, WIF, public key, and Bitcoin address. Runs entirely in your browser.

BIP32 HD key derivation

Derive a Bitcoin BIP32 child private key from either a hex seed or an extended private key (xprv / tprv). The tool returns the child xprv, xpub, raw private key, compressed public key, WIF, fingerprint, and one Bitcoin address for the selected address format.

Everything runs locally in the browser. Private keys and seeds are not uploaded.

Worked example

Use the BIP32 test-vector seed:

seed: 000102030405060708090a0b0c0d0e0f
path: m/0'
network: mainnet
address_type: p2pkh

The output includes the BIP32 vector child key beginning with xprv9uHRZZhk6KA... and the matching xpub68Gmy5Edvgi....

Inputs

Provide exactly one of seed or xprv.
path must start with m and may use hardened suffixes ', h, or H.
network changes xprv/xpub version bytes and address prefixes.
address_type renders one address from the derived compressed public key: legacy P2PKH, wrapped SegWit, or native SegWit.

Limits and edge cases

This is a Bitcoin-only BIP32 private-derivation tool. It does not accept mnemonics directly; use the BIP39 seed tool first, then paste the seed here. It does not derive from xpub-only watch-only keys, address ranges, ypub/zpub version bytes, or altcoin address formats.

Can I paste a mnemonic phrase?

No. First run the mnemonic through the BIP39 seed derivation tool, then paste the resulting 512-bit seed hex here. Keeping mnemonic validation separate keeps the wordlist/checksum logic in one place.

What is the difference between seed and xprv?

A seed is the root entropy used to create the master BIP32 key. An xprv or tprv is already an extended private key at some node. This tool can start from either one, but not both at the same time.

Which address type should I choose?

Use p2pkh for legacy 1... or m/n... addresses, p2sh_p2wpkh for wrapped SegWit 3... or 2... addresses, and p2wpkh for native SegWit bc1... or tb1... addresses.

Can it derive many addresses at once?

No. Enter one explicit path, such as m/84'/0'/0'/0/0. To derive a range, rerun with the last index changed (.../0, .../1, and so on).
