Hi @vishal-kanna. Thank for your interest. There issues for ICS20 v2 are on hold for now. The team has done a PoC and investigation of the required work, but we will pick up this feature most probably during Q2. Until then we need to focus on other priorities. If you're interested, we can contact you later on and then you can help us with some of the issues.

Sure @crodriguezvega .Thank for the reply

Note: the defer telemetry statements are commented out the PoC, but should instead be refactored to account for multi denoms being received.
