`execute` and `send` try to decode the xcm in the parameters before reaching the filter line. The new extrinsics decode only after the filter line. These should be used instead of the old ones. ## TODO - [x] Tests - [x] Generate weights - [x] Deprecation issue -> https://github.com/paritytech/polkadot-sdk/issues/3771 - [x] PRDoc - [x] Handle error in pallet-contracts This would make writing XCMs in PJS Apps more difficult, but here's the fix for that: https://github.com/polkadot-js/apps/pull/10350. Already deployed! https://polkadot.js.org/apps/#/utilities/xcm Supersedes https://github.com/paritytech/polkadot-sdk/pull/1798/ --------- Co-authored-by: PG Herveou <pgherveou@gmail.com> Co-authored-by: command-bot <> Co-authored-by: Adrian Catangiu <adrian@parity.io>

title: "pallet-xcm: deprecate execute and send in favor of execute_blob and send_blob"

pallet-xcm's extrinsics `execute` and `send` have been marked as deprecated.
|
|
Please change their usage to the new `execute_blob` and `send_blob`.
|
|
The migration from the old extrinsic to the new is very simple.
|
|
If you have your message `xcm: VersionedXcm<Call>`, then instead of passing in
|
|
`Box::new(xcm)` to both `execute` and `send`, you would pass in
|
|
`xcm.encode().try_into()` and handle the potential error of its encoded length
|
|
being bigger than `MAX_XCM_ENCODED_SIZE`.
|
|
|
|
pallet-contracts takes the XCM encoded now as well. It follows the same API as
|
|
`execute_blob` and `send_blob`.

pallet-xcm has a new pair of extrinsics, `execute_blob` and `send_blob`.
|
|
These are meant to be used instead of `execute` and `send`, which are now deprecated
|
|
and will be removed eventually.
|
|
These new extrinsics just require you to input the encoded XCM.
|
|
There's a new utility in PolkadotJS Apps for encoding XCMs you can use:
|
|
https://polkadot.js.org/apps/#/utilities/xcm
|
|
Just pass in the encoded XCM to the new extrinsics and you're done.
|
|
|
|
pallet-contracts takes the XCM encoded now as well. It follows the same API as
|
|
`execute_blob` and `send_blob`.
