Authenticators in python v2 client

[konichuvak]

Hi team, any plans on supporting authenticators for enabling permissioned keys functionality?
It looks like v4-proto >=7 already has the right protobufs for it.

I upgraded protobuf==5.29, grpcio==1.70.0 and v4-proto==7.0.5 and tried with the following example, but the transaction fails with "Out Of Gas" error every time.

import asyncio
import base64
import json
import os

from dotenv import load_dotenv
from dydx_v4_client.network import make_mainnet
from dydx_v4_client.node.client import NodeClient
from dydx_v4_client.wallet import KeyPair, Wallet
from v4_proto.dydxprotocol.accountplus.tx_pb2 import MsgAddAuthenticator


load_dotenv()

NODE_URL = 'dydx-grpc.publicnode.com:443'


async def setup_key():

    # Set up a node connection to broadcast transactions to
    network = make_mainnet(
        rest_indexer='',
        websocket_indexer='',
        node_url=NODE_URL
    )
    node: NodeClient = await NodeClient.connect(network.node)

    # Set up the primary wallet for which we want to add authenticator
    wallet = await Wallet.from_mnemonic(
        node,
        mnemonic=os.environ['DYDX_MNEMONIC'],
        address=os.environ['DYDX_ADDRESS'],
    )

    # Derive the public address of the signer wallet from its private key
    key_pair = KeyPair.from_mnemonic(os.environ['DYDX_SIGNER_MNEMONIC'])
    signer_public_key = key_pair.public_key_bytes

    sub_authenticators = [
        {
            'type': 'SignatureVerification',
            'config': base64.b64encode(signer_public_key).decode(),
        },
        {
            'type': 'MessageFilter',
            'config': base64.b64encode(b'/dydxprotocol.clob.MsgPlaceOrder').decode(),
        },
    ]
    request = MsgAddAuthenticator(
        sender=wallet.address,
        authenticator_type="AllOf",
        data=json.dumps(sub_authenticators).encode(),
    )

    transaction = await node.send_message(wallet, request)
    print(transaction)


if __name__ == '__main__':
    asyncio.run(setup_key())

GH-101 Authenticators in python v2 client

The solution was to bump the GAS_MULTIPLIER from 1.4 to 1.6 in the config.py.
Thanks @v0-e for the suggestion in #322
