SmartBERT V2 CodeBERT

Overview

SmartBERT V2 CodeBERT is a pre-trained model, initialized with CodeBERT-base-mlm, designed to transfer Smart Contract function-level code into embeddings effectively.

• Training Data: Trained on 16,000 smart contracts.
• Hardware: Utilized 2 Nvidia A100 80G GPUs.
• Training Duration: More than 10 hours.
• Evaluation Data: Evaluated on 4,000 smart contracts.

Preprocessing

All newline (\n) and tab (\t) characters in the function code were replaced with a single space to ensure consistency in the input data format.

Base Model

• Base Model: CodeBERT-base-mlm

Training Setup

from transformers import TrainingArguments

training_args = TrainingArguments(
    output_dir=OUTPUT_DIR,
    overwrite_output_dir=True,
    num_train_epochs=20,
    per_device_train_batch_size=64,
    save_steps=10000,
    save_total_limit=2,
    evaluation_strategy="steps",
    eval_steps=10000,
    resume_from_checkpoint=checkpoint
)
