Lock an HD Account Type

To avoid errors related to POST xpub and SegWit derivation type, this endpoint allows locking of the type of an xpub in the database.

POST /xpub/:xpub/lock

Parameters must be passed in the body of the request as url encoded arguments.

Parameters

• address - string - The first address of the internal chain for this xpub, derivation path M/1/0. Use compressed P2PHK address regardless of HD derivation scheme.
• message - string - Either "lock" or "unlock"
• signature - string - The base64-encoded signature of the double SHA256 hash of [varuint length of message string, message string]. Signature scheme follows bitcoinjs-message with a message prefix matching the coin type. Use the ECPair associated with the M/1/0 address to sign.
