A proposal to move 15% of the KSM from the Moonriver sovereign account on Kusama chain to Kusama AH for liquidity has passed and been executed. This proposal came after Kusama AH became a reserve for KSM for Moonriver, meaning for KSM can be sent from Moonriver to AH and back. This is set up as a trail run for Moonbeam where a corresponding path enabling the transfer of DOT and other tokens between Polkadot AH and Moonbeam will be set up to enable one-click interactions for Snowbridge and other apps. https://moonriver.polkassembly.io/referenda/62
