Transfer tech debt #8538
Description
- Internal Transfer Representation should be removed
- The denomination in the packet data should be split explicitly into the trace and base denom rather than having the trace and base denom be parsed from the denomination in the packet. This was done in the original ICS20 transfer v2 packet data and it should be brought back in some form.
- Currently the trace only allows for a single port to be specified. In IBC v2, this created problems because counterparty portIDs are no longer strictly bound to each other. If we want to allow transfer to be mapped to a non "transfer" portID. Then we need to have the portIDs from both sides represented in the trace Hop. Otherwise, we can just enforce this requirement of only using the "transfer" port forever.
Once IBC v1 is removed:
- I recommend phasing out the use of memo and simply using contract calls with multipacket data
