AI-POWERED INSIGHTS FOR DECENTRAlIZED FINANCE
Ensemble multi-label machine learning solidity smart contract vulnerability detection model
Blockchain technology has revolutionized digital financial transactions and asset ownership by enabling decentralized and automated operations through smart contracts. Solidity smart contracts, used in the Ethereum blockchain network, facilitate secure and trustless execution of agreements. However, like any code, smart contracts are prone to vulnerabilities. Considering the assets and value of currency these smart contracts handle, their exploitation leads to severe financial losses and loss of operations. Such exploits have resulted in billions of dollars in stolen or locked assets. In this paper, we present an ensemble multilabel classifier model approach for the automated detection of vulnerabilities in Solidity smart contracts using a real smart contract dataset, with a detailed methodological process that includes processing the dataset. The proposed model stack achieves excellent results with F1 scores ranging from 82.0% to 99.9% for each vulnerability dataset. The proposed model is also compared with common static analyzer tools and models proposed in the literature following a similar approach. Moreover, we package the models into a web application, demonstrating deployment and functionality.
Key Outcome: The proposed model stack achieves excellent results with F1 scores ranging from 82.0% to 99.9% for each vulnerability dataset.

Understanding Smart Contract Security Flaws
Common vulnerabilities include reentrancy attacks, integer overflows/underflows, arbitrary memory access, bad randomness or block dependency among other logical vulnerabilities. Exploiting these weaknesses can result in loss of funds, contract manipulation, or destructive unintended behavior.
Leveraging AI for Enhanced Detection
In recent years, machine learning (ML) techniques have also grown in popularity for tasks such as data classification, anomaly detection, and automated decision-making. ML algorithms learn from data and identify patterns that can help in predicting outcomes or detecting irregularities. Within the blockchain and smart contract domain, ML may be employed to detect suspicious transactions, classify. This includes the use of models like Support Vector Machines (SVM), Random Forest Classifiers (RFC), Decision Trees, K-Nearest Neighbors (KNN), Long Short-Term Memory (LSTM) networks, and Convolutional Neural Networks (CNNs).
Deep Dive into Bytecode Analysis
Opcode and pattern analysis-based techniques take a lower-level approach, focusing on analyzing compiled bytecode instructions to detect vulnerabilities. This method is particularly useful in cases where source code is unavailable, as it allows researchers to inspect deployed smart contracts directly. This approach provides high explainability, as detected vulnerabilities can be traced to specific opcode sequences.
