In preparation for the Asset Hub Migration, parachains and dApps will need to take some mandatory action. The *transfer_assets* and *(limited_)reserve_transfer_assets* extrinsics still auto-detect the Relay Chain as the reserve, which would lead to failed transactions and potential trapped funds post-migration. This issue has been patched in the latest SDK, so parachains are advised to upgrade before the migration. In addition, parachains will need to be configured to trust Asset Hub as the reserve for DOT. DApps using the incompatible extrinsics will need to switch to alternatives, such as Paraspell SDK, *transfer_assets_using_type_and_then*, or by using XCM with the correct reserve and then passing it to *execute*.
Referendum 1102 on the OpenGov Medium Spender Track requests 14,092 DOT of retroactive funding for the Kheopswap DEX for Asset Hub. One of the first live DApps built with the Polkadot API (PAPI), Kheopswap already supports swaps, liquidity provisioning, and Asset Hub Relay Chain transfers and teleports. The requested amount would retroactively compensate approximately 480 hours of development.
This week, Hydration inadvertently discovered a 64 asset limit for registering assets from Asset Hub. While they have been assured that a fix will be in the next Asset Hub runtime upgrade, Basti has discovered that the limit can be bypassed by placing a deposit with the "assets::touch" function.
