    var puts fmt.Sprintf

    var builder strings.Builder

    builder.WriteString(puts("0x%x,", blkHash))
    builder.WriteString(puts("%d,", blkHeader.Number))
    builder.WriteString(puts("0x%x,", getFromAddr(tx, big.NewInt(int64(i)))))
    builder.WriteString(puts("0x%x,", txGas))
    builder.WriteString(puts("0x%x,", txGasPrice))
    builder.WriteString(puts("0x%x,", tx.Hash()))
    builder.WriteString(puts("0x%x,", txInput))
    builder.WriteString(puts("%v,", txNonce))
    builder.WriteString(puts("%v,", txTo))
    builder.WriteString(puts("%v,", txValue))
