FAQS

What format should my private key be in?

The private key should be in the base58 string format, not bytes.

Why are my transactions being dropped?

You get what you pay for. Don't use the main-net RPC, just spend the money for Helius or Quick Node.

How do I change the fee?

Modify the unitbudget and unitprice values.

Does this code work on devnet?

No.

Example

from solana.rpc.api import Client
from solders.keypair import Keypair  # type: ignore
from poolutils import fetchpairfromrpc from pump_swap import buy
Configuration
privkey = "base58privstrhere"
rpc = "rpcurlhere"
mintstr = "pumpswap_address"
sol_in = 0.1
slippage = 5
unitbudget = 150000
unitprice = 1000_000
Initialize client and keypair
client = Client(rpc)
payerkeypair = Keypair.frombase58string(privkey)
Fetch pair and execute buy
pairaddress = fetchpairfromrpc(client, mint_str)
if pair_address:
    buy(client, payerkeypair, pairaddress, solin, slippage, unitbudget, unit_price)
else:
    print("No pair address found...")
