Create Balance Transfer using a Proxy

Question

I am trying to initiate a balance transfer call using a proxy with the 'Any' type. I'm using the Python API, which allows me to create and submit the transaction successfully. However, it fails (https://westend.subscan.io/extrinsic/17455468-2). I am able to create the transaction using a wallet for the wallets.

# Compose the transfer call using the balances module
    transfer_call = substrate.compose_call(
        call_module='Balances',
        call_function='transfer',
        call_params={
            'dest': recipient_address,
            'value': transfer_amount,
        },
    )

    # Compose the proxy call to execute the transfer via the proxy
    proxy_call = substrate.compose_call(
        call_module='Proxy',
        call_function='proxy',
        call_params={
            'real': proxy_account,
            'call': transfer_call,
        },
    )

    nonce = substrate.get_account_nonce(keypair.ss58_address)
    signature_payload = substrate.generate_signature_payload(call=call, nonce=nonce)

    signature = keypair.sign(signature_payload)

    extrinsic = substrate.create_signed_extrinsic(
        call=call, keypair=keypair, signature=signature
    )

    print(extrinsic)

    result = substrate.submit_extrinsic(extrinsic=extrinsic, wait_for_finalization=False)

Also, the transaction is listed under the 'Extrinsics' tab in the explorer, rather than the 'Transfers' tab. Any advice on this would be greatly appreciated.

Thank you

The error is clearly visible here.

If this succeeds, it means you can transfer someone's money without their permission.

You must set up the proxy first. Use proxy.add_proxy.
