# XCM Issue
Almost all parachains on Polkadot have already upgraded to XCM V3, however in some cases the Polkadot Relay Chain StorageMap believes that they are still on XCM v2. Teams should validate the following, however on a first analysis by Parity's Data Team, these appear to be the action items by team:
- Teams that need to notify the Polkadot Relay Chain that they are on XCM v3
- Darwinia.
- Unique Network.
- Teams that need to upgrade to XCM v3
- Clover.
- Crust.
- Manta Network.
- Teams that need to review their configuration (accepts both XCM v2 and XCM v3)
- Composable Finance.
In order to know how to notifiy the Polkadot Relay Chain of the right XCM version, we recommend checking out this [tweet thread by Bryan Chen from Acala](https://twitter.com/XiliangChen/status/1722546359071609103), as well as [this discussion on the Moonbeam Community](https://forum.moonbeam.network/t/proposal-mr38-hotfix-for-kusama-fails-to-convert-xcm-from-v3-v2/1366).
It's highly recommended to the community to check and execute the above accordingly before the runtime upgrade is executed on Polkadot.

## Message for teams that need to signal to the Relay Chain
The latest upgrade on Kusama introduced `setTopic` on to XCM, therefore teams need to be on XCM v3 for messages to be passed successfully.
On our investigation you have successfully upgraded to XCM v3, however unfortunately the Relay Chain is not aware of that. In order to check it for yourself, you need to query on the Relay Chain `xcmPallet.supportedVersion` with the parameter `3` and then you can find your paraID and check with version the Relay Chain believes is supported on your parachain.
Response looks something like this:
```
[
[
3
{
V3: {
parents: 0
interior: {
X1: {
Parachain: 2,092 -> your paraID number
}
}
}
}
]
2 -> Version the relay chain believes your parachain has
]
```
**From our investigation, we believe that in your case the Relay Chain believes you are running version 2, therefore a fix is needed.**
The fix is quite straightforward, and it needs you to send a message from your chain to the relay chain notifying it of the right XCM version you are running. This needs to be send via Root from your parachain.
[Here's Moonriver's example message](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fmoonriver.unitedbloc.com#/extrinsics/decode/0x670003010003040379290303000000000000) which you need to replicate, with one change: You need to find the right `queryID` for your chain. In order to do that, please query on the Kusama Relay Chain `xcmPallet.queries` and find your paraID.
Following the example above for `paraID 2,092`, response looks like this:
```
[
[
2,653 -> queryID
]
{
VersionNotifier: {
origin: {
V3: {
parents: 0
interior: {
X1: {
Parachain: 2,092 -> paraID
}
}
}
}
isActive: true
}
}
]
```
Do let me know if anything!

## Finding failed TXs
### Methodology
1. Find all sovereign accounts for parachains on Kusama.
2. Look for all the transfers happening between block 20465806 and the block of the fix for each team.
3. Read into the events associated with the extrinsic in which the transfer happened. We should identify the `xcmpallet (Attempted)` and see whether `Unroutable: Null` is in the response. Example: https://kusama.subscan.io/extrinsic/20466525-4
4. Validate this with Keith.
5. Share this info.
