Export xpub from public key

POST 

/v1/xpub/export

Export xpub based on a EC public-key (secp256k1) with chaincode, network, depth, parentFingerprint and childnumber.

You can derive the public-key directly by specifying a derivation-path in the 'label' like: key-name/1/2/3

Note: Hardened derivation paths (noted by the ' symbol) require access to the private key. This is by design in the BIP-32 specification for hierarchical deterministic (HD) wallets.

  • Normal (non-hardened) derivation: You can derive child public keys from an xpub.

  • Hardened derivation: You must use the private key (i.e., xprv) to derive these child keys.
