    • chain A (ibc-go v5) -> chain B (ibc-go v2)
    • chain A (ibc-go v4) -> chain B (ibc-go v5)
    • chain A (ibc-go v3) -> chain B (ibc-go v5)
    • chain A (ibc-go v2) -> chain B (ibc-go v5)
  • Failed token transfer (e.g. receiver address is not valid)
    • chain A (ibc-go v5) -> chain B (ibc-go v4)
