A Note for Python Devs

Python developers are able to interact with Whirlpool through Whirlpool Essential library!

Whirlpool Essentials library contains almost functions provided by SDK for Typescript.

From the following code, you will find many common codes.

import asyncio

from solana.rpc.async_api import AsyncClient
from solders.pubkey import Pubkey
from solders.keypair import Keypair

from orca_whirlpool.constants import ORCA_WHIRLPOOL_PROGRAM_ID
from orca_whirlpool.context import WhirlpoolContext
from orca_whirlpool.utils import PriceMath, DecimalUtil

SOL_USDC_8_WHIRLPOOL_PUBKEY = Pubkey.from_string("7qbRF6YsyGuLUVs6Y1q64bdVrfe4ZcUUz1JRdoVNUJnm")

async def main():
    connection = AsyncClient(RPC_ENDPOINT_URL)
    ctx = WhirlpoolContext(ORCA_WHIRLPOOL_PROGRAM_ID, connection, Keypair())

    # get SOL/USDC(ts=8) whirlpool
    whirlpool_pubkey = SOL_USDC_8_WHIRLPOOL_PUBKEY
    whirlpool = await ctx.fetcher.get_whirlpool(whirlpool_pubkey)
    decimals_a = (await ctx.fetcher.get_token_mint(whirlpool.token_mint_a)).decimals  # SOL_DECIMAL
    decimals_b = (await ctx.fetcher.get_token_mint(whirlpool.token_mint_b)).decimals  # USDC_DECIMAL

    print("whirlpool token_mint_a", whirlpool.token_mint_a)
    print("whirlpool token_mint_b", whirlpool.token_mint_b)
    print("whirlpool tick_spacing", whirlpool.tick_spacing)
    print("whirlpool tick_current_index", whirlpool.tick_current_index)
    print("whirlpool sqrt_price", whirlpool.sqrt_price)
    price = PriceMath.sqrt_price_x64_to_price(whirlpool.sqrt_price, decimals_a, decimals_b)
    print("whirlpool price", DecimalUtil.to_fixed(price, decimals_b))
