⚠️ Potential issue

Ohayo sensei! Please address SQL injection and input validation concerns.

The implementation needs several security and robustness improvements:

  1. SQL Injection vulnerability: Using string formatting for SQL query construction
  2. No validation of input contract addresses
  3. No limit on number of addresses that can be queried

Consider this safer implementation:

async fn retrieve_tokens(
    &self,
    contract_addresses: Vec<Felt>,
) -> Result<RetrieveTokensResponse, Status> {
+    const MAX_ADDRESSES: usize = 100;
+    if contract_addresses.is_empty() {
+        return Err(Status::invalid_argument("No contract addresses provided"));
+    }
+    if contract_addresses.len() > MAX_ADDRESSES {
+        return Err(Status::invalid_argument(
+            format!("Too many addresses. Maximum allowed: {}", MAX_ADDRESSES)
+        ));
+    }
+
+    let placeholders = contract_addresses
+        .iter()
+        .map(|_| "?")
+        .collect::<Vec<_>>()
+        .join(", ");
+
+    let query = format!("SELECT * FROM tokens WHERE contract_address IN ({})", placeholders);
+
+    let mut query_builder = sqlx::query_as(&query);
+    for address in contract_addresses {
+        query_builder = query_builder.bind(format!("{:#x}", address));
+    }

-    let query = format!(
-        "SELECT * FROM tokens WHERE contract_address IN ({})",
-        contract_addresses

💡 Codebase verification

⚠️ Potential issue

Handle serialization errors gracefully in Token conversion

Ohayo sensei! Looking at the codebase, I can confirm this is a critical issue. The serde_json::to_string(&value.metadata).unwrap() call in the Token conversion could indeed panic. While there are other unwrap usages in the codebase, this one is particularly risky since it's in a type conversion that could be called frequently in production code.

Here's a suggested improvement:

 impl From<Token> for proto::types::Token {
     fn from(value: Token) -> Self {
+        // Serialize metadata, using empty JSON object as fallback
+        let metadata = serde_json::to_string(&value.metadata)
+            .unwrap_or_else(|_| "{}".to_string());
+
         Self {
             contract_address: value.contract_address,
             name: value.name,
             symbol: value.symbol,
             decimals: value.decimals as u32,
-            metadata: serde_json::to_string(&value.metadata).unwrap(),
+            metadata,
         }
     }
 }

The change ensures that even if metadata serialization fails, we'll get a valid JSON object rather than a panic. This is a safer approach for production code.

🔗 Analysis chain

Handle potential serialization errors gracefully

Ohayo sensei! While the implementation is generally good, the unwrap() call on line 27 could panic if the metadata serialization fails. Consider handling this error case gracefully.

Here's a suggested improvement:

 impl From<Token> for proto::types::Token {
     fn from(value: Token) -> Self {
+        // Serialize metadata, using empty JSON object as fallback
+        let metadata = serde_json::to_string(&value.metadata)
+            .unwrap_or_else(|_| "{}".to_string());
+
         Self {

Let's verify if there are similar unwrap patterns in other type conversions:


Let me search for similar patterns in the codebase to verify if this is a common issue or an isolated case.
