SmartBERT V3 CodeBERT

Overview

SmartBERT V3 is a pre-trained programming language model, initialized with CodeBERT-base-mlm. It has been further trained on SmartBERT V2 with an additional 64,000 smart contracts, to enhance its robustness in representing smart contract code at the function level.

Training Data: Trained on a total of 80,000 smart contracts, including 16,000 from SmartBERT V2 and 64,000 (starts from 30001) new contracts.
Hardware: Utilized 2 Nvidia A100 80G GPUs.
Training Duration: Over 30 hours.
Evaluation Data: Evaluated on 1,500 (starts from 96425) 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.
