Just Want to Help ATA Fetch

[Relic999]

After a successful buy transaction on pump.fun, attempting to sell immediately fails with:
solana.rpc.core.RPCException: InvalidParamsMessage { message: "Invalid param: could not find account" }

This happens when calling get_token_account_balance() even though the buy transaction confirmed successfully and created the Associated Token Account (ATA).

Root Cause:

The issue occurs due to RPC node synchronization delays. When you:

Send a buy transaction that creates an ATA and deposits tokens
Transaction confirms on one RPC node
Immediately query for the token balance
The query might hit a different RPC node that hasn't synced the new account yet
The Fix:

Before (fails when ATA isn't synced):
token_balance = await self.client.get_token_account_balance(user_token_account)

After (with fallback to raw account data):
try:
token_balance = await self.client.get_token_account_balance(user_token_account)
except Exception as e:
if "could not find account" in str(e).lower():
logger.warning(f"Token account not found via RPC, checking raw account data")
try:

Fallback: Get raw account data and parse token amount manually

from solana.rpc.api import Client
client = Client(self.client.rpc_endpoint)
account_info = client.get_account_info(user_token_account)
if account_info.value and account_info.value.data:
data = account_info.value.data
if len(data) >= 72:
import struct

SPL Token account layout: owner (32 bytes), mint (32 bytes), amount (8 bytes at offset 64)

token_balance = struct.unpack('<Q', data[64:72])[0]
logger.info(f"Got token balance from raw data: {token_balance}")
else:
token_balance = 0
else:
token_balance = 0
except Exception as e2:
logger.error(f"Failed to get raw account data: {e2}")
token_balance = 0
else:
raise # Re-raise if it's a different error
Why This Works:

First attempt: Try the standard get_token_account_balance() RPC method
If account "not found": Fall back to get_account_info() which often succeeds even when the specialized method fails
Parse manually: Extract the token amount from raw bytes (SPL Token accounts store the amount as a little-endian u64 at byte offset 64)
Additional Considerations:

This is a temporary workaround for RPC inconsistency
The issue is more common with fast-paced trading where you buy and sell within seconds
Some RPC providers (like Helius) have better consistency than public endpoints
Adding a small delay (1-3 seconds) after buy can help but impacts trading speed

Thanks to the project team. I can't find this executable file in the repository, where can I find it or is there a replacement file? Thanks

Ahhh I see they made an update. I don't have the original bot file anymore. I completely rewrote the bot in Rust. It's about 20x Faster

Thanks, do you have a bot written in rust publicly available?

Wow, fast! Did it help to land a tx in the same slot with a mint? Also, could you clarify the reason you opened this issue? What's your suggestion?

Please refrain from asking the same question in multiple issues, thanks. Here it is https://github.com/chainstacklabs/pumpfun-bonkfun-bot/blob/main/learning-examples/listen-migrations/listen_blocksubscribe_old_raydium.py

Hey! I Opened the issue because the bot had an issue With the ATA I wanted to let you guys know about. If there is no ata created the sell function was not worknig so i gave you guys the fix in my OP to handle it

So, your suggestion is getting account info instead of account balance? It worked despite those syncing issues?

[Relic999]

yes it works perfectly the way the script is running now your getting error at insctuction 4 because your not getting the ATA and the tx is failing The fix is:
Add a 2-second delay for RPC sync for ATA
Implement retry logic (3 attempts)
Fix the fallback to use the async client's get_account_info directly
Add proper parsing of token balance from raw account data

Are you sure that a tx is failing? You can see errors while simulating it (it's expected behaviour since a node may not have the latest state) and it actually lands to the chain (because a leader runs it again leader's latest state). Also, your solution still requires delays. I don't think it improves the flow 🤔
