How create an ExtrinsicPayload and sign it on another machine.

Hello,

1. basically I just want to create the ExtrinsicPayload on machine A connected to my node
2. then send it over the network (http) to machine B which has access to my keys for signing
3. then pass again the signature to machine A for sending the transaction.

I tried to pass the signerPayload.toPayload() from A to B it works fine as it is JSON. But I’m missing the api.registry to createType(registry, "ExtrinsicPayload", payload, { version: payload.version }).sign(keys);. I tried to play with Codec to encode on A and decode on B, but same problem, I’m missing the api.registry .

Any suggestions ?

Yes. So machine A has a connection, machine B just needs a way to get access to the hex payload, it never connects to sign.

Mortals are always recommended. However, if you wish to forgo protection it provides, you can (in the above tools) pass --blocks 0 and it will create an immortal on construction.
