Hello guys i am trying to get the metadata as a 0x${string} type. I am calling the api endpoint state_getMetadata with await api.rpc.state.getMetadata() however this returns an object of Metadata and i am trying to do offline singing of transctions.

I have followed the github examples where they are doing same thing however when i try to sign the transaction it wants the metadata to be of type 0x${string} how do i properly convert or implement this?

thanks in advance

In order to have the return value of await api.rpc.state.getMetadata() be a type of 0x${string} all you need to do is call .toHex() on the return type.

So:

const metadata = await api.rpc.state.getMetadata();
const metadataHex = metadata.toHex();
