v2.3.0

Minor Changes

• 40589c2: Add non-blocking variants for signing Batch payloads. xrpl.signBatchPayload proposes the raw sign intent and returns a serializable handle without waiting for the manifest signature, and xrpl.getBatchSignature fetches the signature (single-shot by default, optional polling) for that handle once the custody instance operator has approved it. Use these when operator approval happens out-of-band; signBatchPayloadAndWait remains for the synchronous case.

  signBatchPayload (and therefore signBatchPayloadAndWait) now validates signerAddress with isValidAddress and throws a CustodyError if it is not a valid XRPL address.
