Priority fees

[iLewisMC]

How do I add priority fees. Ive made a test file to try and see which parmeter it needs ive even been through the whole src and I cant seem to get it working. Swaps are working fine when I dont try to define priority fee.

CODE: `import asyncio import base58 from solders.keypair import Keypair from solana.rpc.async_api import AsyncClient from jupiter_python_sdk.jupiter import Jupiter import json import os import logging

Set up logging

logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s: %(message)s') logger = logging.getLogger()

async def test_priority_fee_parameters(): """Test different parameter names for priority fee"""

# Load your wallet
wallet_path = 'wallets.json'  # Update this path if needed

with open(wallet_path, 'r') as f:
    wallet_data = json.load(f)

# Get private key from wallet
private_key_bytes = base58.b58decode(wallet_data['private_key'])
keypair = Keypair.from_bytes(private_key_bytes)

# Initialize RPC client
rpc_endpoint = "https://api.mainnet-beta.solana.com"
async_client = AsyncClient(rpc_endpoint)

# Initialize Jupiter
jupiter = Jupiter(
    async_client=async_client,
    keypair=keypair,
    quote_api_url="https://quote-api.jup.ag/v6/quote?",
    swap_api_url="https://quote-api.jup.ag/v6/swap"
)

# Get a quote first (small amount to avoid actual swaps)
logger.info("Getting quote...")
quote = await jupiter.quote(
    input_mint="So11111111111111111111111111111111111111112",  # SOL
    output_mint="EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",  # USDC
    amount=100000  # 0.0001 SOL - very small amount
)

if not quote:
    logger.error("Failed to get quote")
    return

logger.info("Quote received successfully")

# Test different parameter names
test_params = [
    'prioritization_fee',
    'prioritizationFee',
    'prioritization_fee_lamports',

for param_name in test_params:
    try:
        logger.info(f"Testing parameter: {param_name}")
        
        # Create parameters dictionary dynamically
        params = {

            'slippage_bps': 100,
            param_name: 10000  # 10,000 lamports priority fee
        }
        
        # Try to get swap transaction data (but don't execute it)
        transaction_data = await jupiter.swap(**params)
        
        # If we get here, it worked!
        logger.info(f"✅ SUCCESS with parameter: {param_name}")
        return param_name
        
    except Exception as e:

return None

async def main(): result = await test_priority_fee_parameters() if result: print(f"\n✅ The correct parameter name is: {result}") else: print("\n❌ Could not determine the correct parameter name")

Same problem here, anyone got a way to use priority fees ?

Solved it, project on Pypy is an older version that doesn't have the priority fees implemented. Solved it by downloading the zip on github and using it locally
