Hello,

First of all, thank so much for the work.

I had the following issue

Subscribed to blocks mentioning program: 6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P

I used below in config file

from solders.pubkey import Pubkey

PUMP_PROGRAM = Pubkey.from_string("6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P")
PUMP_GLOBAL = Pubkey.from_string("4wTV1YmiEkRvAtNtsSGPtUrqRYQMe5SKy2uB4Jjaxnjf")
PUMP_EVENT_AUTHORITY = Pubkey.from_string("Ce6TQqeHC9p8KetsN6JsjHK7UTZk7nasjjnr7XxXp9F1")

SOL = Pubkey.from_string("So11111111111111111111111111111111111111112")
LAMPORTS_PER_SOL = 1_000_000_000

RPC_ENDPOINT = "https://api.mainnet-beta.solana.com"
WSS_ENDPOINT = "wss://api.mainnet-beta.solana.com"

I saw that someone had the same issue on ticket #13 but except the message "RPC was the problem" I don't know how he solved it

Could you please help me ?

Thank you

You are using the free public RPC endpoints. Those are used by thousands of users for one-off actions like a token transfer etc. They won't work for heavy production usage. I suggest you start by getting a node eg on the free Chainstack developer plan or a paid one. Just make sure you are aware of the requests per second limits (RPS) and handle them in your script too.

• Chainstack Solana nodes
• All limits to consider
