            createAssociatedTokenAccountIdempotentInstruction(payer.publicKey, user_quote_token_account, payer.publicKey, NATIVE_MINT),
            SystemProgram.transfer({
                fromPubkey: payer.publicKey,
                toPubkey: user_quote_token_account,
                lamports: Number(quote_amt),

            createSyncNativeInstruction(user_quote_token_account)
        );
        
    buyTx.add(
        await pSwap.getBuyInstruction(base_amt, quote_amt, {
            pool,
            baseMint: base_mint,
            quoteMint: NATIVE_MINT,
            baseTokenProgram: TOKEN_PROGRAM_ID,
