Solidity metrics

This project is a static analysis based metric calculator tool for Solidity smart contract programs. It is a Work In Progress, supporting the following metrics

Parameter	Description	Data Type
Address	The smart cotract Address on the ethereum blockchain	address (20 bytes)
CV	Compiler Version	String
FS	The First time the smart contract has been Seen on the blockchain	Date
LS	The Last time the smart contract has been Seen on the blockchain	Date
NA	Number of Asserts	Number
NC	Number of contracts	Number
NCL	Number of Comment Lines	Number
NF	Number of Functions	Number
NFM	Number of function modifiers	Number
NM	Number of Mapping types	Number
NP	Number of modifier Payable	Number
NRq	Number of requires	Number
NRv	Number of reverts	Number
NSCL	Number of Source Code Lines	Number
McCC	McCabe’s cyclomatic complexity	Number

User instructions

Download and compute the metrics

cd examples
python3 smartcontracs-from-etherscan.py

Data Analysis with Pandas and Python

cd examples
jupyter notebook &

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt

df = pd.read_csv('solmetant.csv', sep=';')
df.sort_values(by=['CV'], inplace=True)
df.head()

plt.figure(figsize=(20,5))
sns.swarmplot(x = 'CV',y='SLOC',data=df, size=5)
plt.show()
