PumpZone.funJito Bundles
To get a transaction for signing and sending, you need to make a POST request to the REST API entry point
https://pumpzone.fun/api/v2/trade
The request body contains an array of JSON payloads, each of them is describing its own transaction. You can create up to 5 transactions in one array
Examples
import requests
import base58
from solders.keypair import Keypair
from solders.transaction import VersionedTransaction
from solders.message import from_bytes_versioned
from solders.commitment_config import CommitmentLevel
from solders.rpc.requests import SendVersionedTransaction
from solders.rpc.config import RpcSendTransactionConfig
user_keypairs = [
Keypair.from_base58_string('Your base58 private key here'), # First
Keypair.from_base58_string('Your base58 private key here'), # Second
]
res = requests.post('https://pumpzone.fun/api/v2/trade',
headers = {"Content-Type": "application/json"},
json = [
{
'pub_key' : str(user_keypairs[0].pubkey()),
'mint' : '6WsLDhrc3hURPx5Rn3e12rBoRiXnj4F13K27uVn6stMF', # Token address
'action' : 'buy', # 'buy', 'sell' or 'create'
'amount_sol' : 0.5, # The amount of SOL
# 'amount_tokens' : 10**6, # or the amount of tokens to buy
'slippage' : 25, # The percent slippage allowed (1 .. 100)
'priority_fee' : 0.0005 # Amount to use as priority fee
},
{

'mint' : '6WsLDhrc3hURPx5Rn3e12rBoRiXnj4F13K27uVn6stMF', # Token address
'action' : 'sell', # 'buy', 'sell' or 'create'
