2 weeks ago Hi @pascaloberle! The data variable contains a payload, input data for the instruction. In this case, we specify the amount of tokens we're willing to buy and the max amount of SOL we're happy to spend (including slippage).
10**6 means converting the amount into microunits. SLP tokens usually have 6 decimal places.
Hi all and thanks for the great code and support! I just see my transactions are confirmed

1 Pump.fun instruction
I am not sure if I can be missing anything from the instructions { amount:{ type: "u64" data:"29994001" } maxSolCost:{ type:"u64" data:"13500000" } }
From the code below in the transaction
data = discriminator + struct.pack("<Q", int(token_amount * 10**6)) + struct.pack("<Q", max_amount_lamports)?are you able to derive a bit more what the token_amount * 10**6 is supposed to represent? is it just the amount of token to buy offset to million for some reasons? I just suspect (just a guess at this stage) that there could be some problem with the amount but not too sure
