 # SmartBERT V2 CodeBERT
@@ -37,6 +39,9 @@ SmartBERT V2 can be used for tasks such as:
 - Smart contract classification
 - Code embedding and retrieval
 
+SmartBERT V2 is a pre-trained model specifically developed for **[SmartIntent V2](https://github.com/web3se-lab/web3-sekit)**. It was trained on **16,000 smart contracts**, with no overlap with the SmartIntent V2 evaluation dataset to avoid data leakage.  
+For production use or general smart contract representation tasks, we recommend **SmartBERT V3**: https://huggingface.co/web3se/SmartBERT-v3

 ## Training Data
@@ -45,6 +50,9 @@ SmartBERT V2 was trained on a corpus of approximately **16,000 smart contracts**
 
 To better model smart contract behavior, contracts were processed at the **function level**, enabling the model to learn fine-grained semantic representations of smart contract functions.
 
+For benchmarking purposes in the **SmartIntent V2**, the pretraining corpus was intentionally limited to this **16,000-contract dataset**.  
+The **evaluation dataset (4,000 smart contracts)** was strictly held out and **not included in the pretraining data**, ensuring that downstream evaluations remain unbiased and free from data leakage.
