public final class Json

  1. Object
  2. Json

A small JSON reader and writer shared by the device and the server, for the JSON-RPC framing and EIP-712 documents the crypto packages exchange.

Objects read as LinkedHashMap<String, Object> in document order, arrays as ArrayList<Object>, strings as String, true/false as Boolean, null as null, and numbers as Long when integral and in range, UInt256 when integral, positive and beyond a long, and Double otherwise – a double would silently round a chain quantity.
