error handling support to make transfer atomic

Open 0x8f701 opened this issue 4 years ago • 2 comments

since error handler & callback has been integrated into polkadot-v0.9.11 (xcm v2), we can try to use callback/error_handler to make the transfer atomic

some barriers will need to be opened and ResponseHandler needs also to be set to PolkadotXcm to make this work.

I didn't have a detailed idea for this yet. Maybe xTokens can inherit pallet-xcm and call report_outcome_notify before sending the xcm message?
