It is possible to transpose the first data frame and then transform it by pivoting.

import pandas as pd
import numpy as np
import io

data = '''
QTY EUR
timestamp 1610116649 1610116649
transactions 12 30
'''

df = pd.read_csv(io.StringIO(data), delim_whitespace=True)
df = df.T
pd.pivot(df, index='timestamp', columns='index', values='transactions')

index   EUR     QTY
timestamp       
1610116649  30  12
