Investigation of stuck IBC transactions

[KamuelBob]

From previous times when IBC transfers weren't as user friendly in the Cosmos Ecosystem and the IBC module did not have the protections in place that it has today, a number of IBC transfers were made to expired clients that never properly failed and as a result the user funds have not been returned.

In particular, Keplr IBC transfers would default to channel-0 if no channel was entered and this was an expired channel to the Cosmos Hub.

You can see at the above link that recent transactions attempted to this channel have failed, however a number of earlier transactions were reported as successful however were reported as never having arrived at the destination.

Is there a method such as migration of the expired channel (such as recently done on the Chihuahaua blockchain) that would return the user funds?

Hi @KamuelBob

Could you please provide us with at least a single TX ID of such IBC transfer so we can first and foremost - verify whether the IBC transfer has really stuck (i.e. never arrived nor returned back). ?

PM sent.

after looking at the TX, it looks like the funds indeed stuck.

I think we should revive the expired channel as suggested
