this is not in polkadot-sdk repo so how do we want to test it on westend?
I will also port it there. I wanted to include it in the next release if possible. People are having more and more these problems of proxies not being on AH and similar. This pallet could solve the issue without requiring a root referendum (we already had one and another is prepared AFAIK). |

I'd be more comfortable if we also did a security audit for this before adding it to live Polkadot AssetHub |
The scope of the changes is quite narrow. Doing some proper review should be fine. The only difference to the real |

There is also a TryConvert for fallible conversions

This is probably interesting for downstream proxy dApps. Going to ping this to some people.

It also means that this is the maximum time after which removal of a proxy will be visible here, or? So users will need to be aware that there is a delay of removing a proxy now.

Could use defensive_proof here to get a production error log.

I guess in the case that there are multiple proxies and no force type, it will just pick the first one?
Should not produce issues i think, just an observation.
Release 1.4.2 for: - #535 (PAH and KAH) - #614 (P Collectives) - #604 (PAH and KAH) --------- Signed-off-by: Oliver Tale-Yazdi <[email protected]>
This adds remote proxy support to AssetHub on Polkadot and Kusama. Currently it is configured only to support using proxies registered on the relay chain to work on AssetHub. In the future this can be expanded.
