Zero address appearing as sender in testnet when minting IBC tokens

[Farhad-Shabani]

Context

While testing a sample token transfer on testnet, it was observed that the sender address appears as 0x00…0. This occurs because ICS-20 directly mints the token into the recipient’s account, making the sender address zero, instead of showing the actual ICS-20 contract as the sender.

Proposal

We can first mint the tokens to the ICS-20 contract itself and then perform the transfer. This ensures that the ICS-20 address is correctly reflected as the sender.

Remark

(Since token creation happens only once, this approach should not introduce any significant overhead.)
It actually should be observed for the minting (not just token creation) process as well.

This is fixed for mint.

But we forgot to do the same for burn.
