IBC transfer 应用模块会保存该模块所绑定端口的状态，以及面额追踪信息。
  • PortKey: 0x01 -> ProtocolBuffer(string)
  • DenomTraceKey: 0x02 | []bytes(traceHash) -> ProtocolBuffer(Denom)
  • DenomKey : 0x03 | []bytes(traceHash) -> ProtocolBuffer(Denom)
The IBC transfer application module keeps state of the port to which the module is binded and the denomination trace information.
  • PortKey: 0x01 -> ProtocolBuffer(string)
  • DenomTraceKey: 0x02 | []bytes(traceHash) -> ProtocolBuffer(Denom)
