I heard that there is software for cross chain transfer. Have you used it before?
The only way probably is the huobi exchange. I used safepal before and its one of the best cross chain platform that can easily teade different coins and blockchains. But Im not sure whether they already supporting the hecochain.
Try evodefi, heard they already supported hecochain. Only few or none yet are into hecochain except those dedictaed platform for them.
