PumpSwap: Program Error: "Instruction #4 Failed - Unknown instruction error"

[vedthemaster]

I am trying to perform the manual swap, and I have enough SOL in my wallet. Do you know if the pool requires the WSOL? I performed the same swap using jup to compare : https://solscan.io/tx/AFDWJvP5W8i7jaYjej2uDV28c7QrhLR8EVpovq1BiWmHQ2X5wd5iY7yhLcTLeDxpyPyLPZivLsAiE8yVxgqNALN

I compared both and found out, the failed one does not have the 2 inner instructions for transferchecked.

Error log :

#4

Right, you need WSOL to perform swaps in PumpSwap pools.

So, do I need to handle it in the code or manually wrap the SOL?

Try to do that manually and please let me know how it goes. I will add it to our backlog 😃

Hey, I tried wrapping the SOL

`

# 1. Create wSOL ATA (idempotent)
    create_wsol_ata_ix = create_idempotent_associated_token_account(
        payer.pubkey(),
        payer.pubkey(),
        SOL,
        SYSTEM_TOKEN_PROGRAM
    )
    # 2. Transfer SOL to wSOL ATA (wrap SOL)
    wrap_amount = int(sol_amount_to_spend * LAMPORTS_PER_SOL)
    transfer_sol_ix = transfer(
        TransferParams(
            from_pubkey=payer.pubkey(),
            to_pubkey=user_quote_token_account,
            lamports=wrap_amount
        )
    )
    # 3. Sync native wSOL account after wrapping SOL
    sync_native_ix = sync_native(
        spl_token.SyncNativeParams(
            program_id=SYSTEM_TOKEN_PROGRAM,
            account=user_quote_token_account
        )
    )

`

And think this one is working as well, but still, I am getting an insufficient funds error.

I think I found the cause of the error. I am only wrapping the SOL that is needed for the swap transfer with the pool, but it does not have extra WSOL for the protocol fee. Can you please guide me on how to calculate the protocol fee as well when wrapping the SOL? Is it a fixed fee or does it vary depending on the swap amount?

Thanks

Has anyone been able to resolve this error?

There was no error when running the bot to buy new tokens that initiated on pump.fun, my buy transactions went through. But then I wasn't able to buy tokens that graduated from PumpSwap with various errors.

I see @vedthemaster seemed to resolve the error with wrapping the SOL.

Add these instructions after the compute limit and compute price instructions. This should solve the issue.

@vedthemaster Thanks! If you have time, it would be great to submit a PR with these lines :) Else I could do that a bit later too.

I believe the issue has been resolved thanks to @vedthemaster. @alextancoding please pull the latest code from the main branch.
