There was a problem hiding this comment.
@claravanstaden Do we have any trapped funds in Polkadot? If so, do we need some migration?

The inbound-queue v2 message converter falls back to the Snowbridge sovereign account on AssetHub as the asset claimer when no explicit claimer is supplied. Previously this fallback used
AccountId32 { network: None, .. }, which did not match the location AssetHub's signed-origin converter produces (it setsnetwork: Some(LocalNetwork)). The trap-key hash stored onAssetsTrappedtherefore could not be matched by a signedpolkadotXcm.claim_assetscall, making default-claimer trapped funds effectively unrecoverable without a runtime upgrade.This PR sets
network: Some(LocalNetwork::get())on the fallback claimer so itsLocationagrees with whatSignedToAccountId32<_, _, LocalNetwork>yields on AssetHub, and adds a test covering the no-claimer-supplied path.
