# Usage

```python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_path = "PATH_TO_THIS_REPO"

tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(
    model_path,
    device_map="auto",
    torch_dtype='auto'
).eval()

# Prompt content: "hi"
messages = [
    {"role": "user", "content": Move_Smart_Contract}
]

input_ids = tokenizer.apply_chat_template(conversation=messages, tokenize=True, add_generation_prompt=True, return_tensors='pt')
output_ids = model.generate(input_ids.to('cuda'))
response = tokenizer.decode(output_ids[0][input_ids.shape[1]:], skip_special_tokens=True)

# Model response: "-- Vulnerabilites --"
print(response)

# L3_8B_Aptos_Smart_Contract_Analyser

L3_8B_Aptos_Smart_Contract_Analyser is a cutting-edge AI model designed for comprehensive analysis and security auditing of smart contracts on the Aptos blockchain. We utilized the `ArmurAI/L3_8B` base model, enhanced it with extensive knowledge of Aptos-specific vulnerabilities and best practices, and fine-tuned it with a vast dataset of both secure and vulnerable smart contracts.

# Key Features of L3_8B_Aptos_Smart_Contract_Analyser:

## Advanced Vulnerability Detection

Identifies critical security flaws in Aptos smart contracts:

- Reentrancy vulnerabilities specific to Aptos' resource-oriented architecture
- Unauthorized access to sensitive functions or resources
- Integer overflow/underflow issues in financial calculations
- Improper error handling that could lead to unexpected contract behavior
- Resource exhaustion attacks unique to Aptos' gas model

## Move-Specific Security Analysis

Leverages deep understanding of the Move language to detect:

- Incorrect usage of Move's ownership and borrowing rules
- Potential violations of linear logic principles in resource management
- Unsafe type casting or conversions that could compromise contract integrity

## Aptos Module Interaction Auditing

Identifies risks in inter-module interactions:

- Unauthorized calls to privileged functions in other modules
- Potential front-running vulnerabilities in multi-step operations
- Inconsistent state management across module boundaries

## Tokenomics and Access Control Verification

Scrutinizes:

- Flaws in token distribution mechanisms that could lead to unfair advantages
- Weaknesses in role-based access control implementations
- Potential centralization risks in governance structures

## Smart Contract Upgrade Vulnerabilities

Detects:

- Insecure upgrade patterns that could lead to loss of funds or contract takeover
- Inconsistencies between different versions of upgraded contracts
- Potential backdoors or hidden admin functions in upgradeable contracts
By incorporating these features, L3_8B_Aptos_Smart_Contract_Analyser not only enhances the security of your Aptos smart contracts but also improves their efficiency and quality. Whether you're a seasoned Aptos developer or new to the ecosystem, our model provides invaluable support throughout your development lifecycle.
