@yaruwangway Quick question here. Is there a plan to upgrade Cosmos SDK to v0.44.1? If so, we are going to have to bump up the SDK version in liquidity module and release a new version.

Hi @kogisin yes, we bumped to 0.44.1 (sorry for the late reply). v0.44.0 is not safe to use when performing v0.42->v0.44 in-place store upgrades in vega upgrade.
