What does it do?
The asset id of
pallet_asset_tx_paymentis replaced byMultiLocationfromu32. This is useful to adapt to the newest polkadot-api and polkadot-extension since their default implementation expects aMultiLocation.What important points should reviewers know?
Needs to be merged after merge of #1398 !
pallet_asset_tx_paymentwill fail for a transaction in the standalone mode. However, using thetransaction_paymentpallet,ZTGcan still be used in this case.The PR was tested against a local network forked using chopsticks. I could execute transactions using
USDCfrom AssetHub as fee payment asset.It is important to know that in case the Polkadot API team doesn't incorporate the suggested PR from us, we could still fix the issue mentioned below by using an override as implemented here.
UPDATE: It is important to use a polkadot API types version that includes this PR, otherwise we would need the override described above. This is the case for a polkadot api version higher than or equal to
15.5.2.Is there something left for follow-up PRs?
What alternative implementations were considered?
Are there relevant PRs or issues?
