ChainXS

ChainXS is a macOS application built in Swift which facilitates derivation of secp256k1 elliptic curve public / private keys and addresses from a private mnemonic or an public / private extended Key.

Input

• BIP39 mnemonic (12, 15, 18, 21 or 24 words) with optional passphrase
• BIP32, BIP49 or BIP84 extended public key (xpub, ypub, zpub)
• BIP32, BIP49 or BIP84 extended private key (xprv, yprv, zpprv)

Derivation paths

• BIP32 private (starting with "m") and public (starting with "M") derivation path

Derivable keys and addresses

Public

• Public key
• Bitcoin address (P2PKH)
• Bitcoin address (P2SH-P2WPK)
• Bitcoin address (P2WPKH)
• Extended public key (xpub)
• Extended public key (ypub)
• Extended public key (zpub)
• Ethereum address
• Tron address
• Kaspa address

Private

• Private key
• Private key (WIF)
• Extended private key (xprv)
• Extended private key (yprv)
• Extended private key (zprv)

File export

• ChainXS allows encrypted file export and import of mnemonic or extended key and derivation path
