How to query for All Pallets StorageVersions

Question

Is there an easy way to get a list of all pallets storage versions? An output like this: [ Palletname, StorageVersion ]

Is it possible to query using curl and the rpc for the storage version of all pallets or does anyone have some commandline fu that can do this?

Thanks!

Answer 1

Getting the pallet version from polkadot-js-api is as simple as:

await api.query.system.palletVersion()

You can wrap this in a script to give you all of the pallet versions:

Answer 2

the way to do it with js is to loop the pallets and query storageVersion and validate the returned payload:

api.query.$pallet.storageVersion
