AI Summary

The XCM execution fee is intended to be paid in HDX from Bifrost’s sovereign account on Hydration. Unused HDX is returned to that sovereign account.

The recovery call was tested using Chopsticks against a snapshot of chain state. The test verified that the BNC was delivered to the beneficiary and that the other checked trapped assets were unaffected.

The proposal preimage is whitelist.dispatchWhitelistedCallWithPreimage, with hash:

0x914edf13833eacbcb9787210f6b9d2aed114d1760b2d026aca81360687c3d66b
