vertex-protocol

Vertex Protocol Python SDK

This is the Python SDK for the Vertex Protocol API.

See SDK docs to get started.

Requirements

• Python 3.9 or above

Installation

You can install the SDK via pip:

pip install vertex-protocol

Basic usage

Import the necessary utilities:

from vertex_protocol.client import create_vertex_client, VertexClientMode
from vertex_protocol.contracts.types import DepositCollateralParams
from vertex_protocol.engine_client.types.execute import (
    OrderParams,
    PlaceOrderParams,
    SubaccountParams
)
from vertex_protocol.utils.expiration import OrderType, get_expiration_timestamp
from vertex_protocol.utils.math import to_pow_10, to_x18
from vertex_protocol.utils.nonce import gen_order_nonce

Create the VertexClient providing your private key:

print("setting up vertex client...")
private_key = "xxx"
client = create_vertex_client(VertexClientMode.MAINNET, private_key)

Perform basic operations:

# Depositing collaterals
print("approving allowance...")
approve_allowance_tx_hash = client.spot.approve_allowance(0, to_pow_10(100000, 6))
print("approve allowance tx hash:", approve_allowance_tx_hash)

print("querying my allowance...")
token_allowance = client.spot.get_token_allowance(0, client.context.signer.address)
print("token allowance:", token_allowance)

print("depositing collateral...")
deposit_tx_hash = client.spot.deposit(
   DepositCollateralParams(
      subaccount_name="default", product_id=0, amount=to_pow_10(100000, 6)
   )
)
print("deposit collateral tx hash:", deposit_tx_hash)

# Placing orders
print("placing order...")
owner = client.context.engine_client.signer.address
product_id = 1
order = OrderParams(
   sender=SubaccountParams(
      subaccount_owner=owner,
      subaccount_name="default",
   ),
   priceX18=to_x18(20000),
   amount=to_pow_10(1, 17),
   expiration=get_expiration_timestamp(OrderType.POST_ONLY, int(time.time()) + 40),
   nonce=gen_order_nonce(),
)
res = client.market.place_order({"product_id": product_id, "order": order})
print("order result:", res.json(indent=2))

Running locally

1. Clone github repo

2. Install poetry

$ curl -sSL https://install.python-poetry.org | python3 -

1. Setup a virtual environment and activate it

$ python3 -m venv venv
$ source ./venv/bin/activate

1. Install dependencies via poetry install
2. Setup an .env file and set the following envvars

CLIENT_MODE='mainnet|sepolia-testnet|devnet'
SIGNER_PRIVATE_KEY="0x..."
LINKED_SIGNER_PRIVATE_KEY="0x..." # not required

Run tests

$ poetry run test

Run sanity checks

• poetry run client-sanity: runs sanity checks for the top-level client.
• poetry run engine-sanity: runs sanity checks for the engine-client.
• poetry run indexer-sanity: runs sanity checks for the indexer-client.
• poetry run contracts-sanity: runs sanity checks for the contracts module.
