245-256: Excellent error handling improvement, sensei!The new error handling gracefully handles metadata fetch failures by:
- Returning an empty string instead of failing
- Properly logging warnings for debugging
- Allowing token registration to proceed
Consider adding metrics/monitoring for failed metadata fetches to track the health of external metadata services.
Consider adding the following metrics:
- Counter for failed metadata fetches
- Histogram for metadata fetch latency
- Counter for empty metadata fallbacks

106-110: Ohayo! LGTM - SQL conditions for metadata validation
The added SQL conditions properly ensure that only tokens with valid metadata are returned.
303-303: LGTM - Struct update aligns with SQL changes
The metadata field type change from Option<String> to String correctly reflects that metadata will always be present due to the SQL conditions.
241-243: Metadata parsing looks good, sensei!
The assumption that metadata is always JSON is now safe due to the SQL conditions. However, let's verify that all existing metadata in the database is valid JSON.
✅ Verification successful
Metadata parsing is safe, sensei!
Based on the codebase analysis, the assumption that metadata is always JSON is valid because:
- The metadata is properly handled across the codebase with proper JSON parsing and error handling
- The SQL schema shows metadata is stored in a dedicated column with proper constraints
- The token metadata is fetched and validated before storage, with special handling for edge cases (e.g., control characters filtering in Loot Survivor NFT)
The expect("metadata is always json") is justified as the codebase ensures JSON validity before storage.

122-126: Ohayo! Consistent metadata validation across token types
The SQL conditions mirror those in token_balance.rs, maintaining a consistent approach to metadata validation.
270-272: Consistent metadata handling, sensei!
The metadata handling changes align with those in token_balance.rs, maintaining consistency across the codebase.

Do we want to ignore the tokens without metadata? We may return them and the front will see that they are missing, or do we have an other reason?
There was a problem hiding this comment.
there are few cases like nft got burned in which case the metadata would no longer be present, but we still need them in db since the token id is foreign key in other tables.
and also in some cases contracts don't follow the spec properly or the json metadata is broken, etc... even in those cases we still want indexing to happen normally and we would just ignore those tokens

But only metadata is ignored, or the whole token? The whole token, right?

yeah whole token, because without metadata there is no attributes, images, etc... so i dont think UI can do much with the token anyways

106-109:
Ohayo sensei! Consider revising the metadata condition.
The SQL condition allows NULL metadata, but the struct BalanceQueryResultRaw expects metadata to always be present. This could lead to runtime errors if a NULL value is encountered.
Consider either:
- Updating the SQL condition to ensure metadata is always present:
- "(t.metadata IS NULL OR length(t.metadata) > 0)".to_string(),
+ "(t.metadata IS NOT NULL AND length(t.metadata) > 0)".to_string(),- Or keeping metadata as
Option<String>in the struct if NULL values are expected.
Likely invalid or redundant comment.
302-302: Verify metadata handling consistency.
The change from Option<String> to String requires that metadata is always present and valid. This needs to be enforced consistently across:
- SQL queries
- JSON parsing
- Data insertion logic
✅ Verification successful
Ohayo sensei! Based on the findings, I can now provide a final response:
Metadata field change is safe and consistent with implementation
The change from Option<String> to String for metadata is properly enforced by the system:
- The SQL schema shows metadata is handled at insertion time in
crates/torii/core/src/executor/erc.rs - The token insertion query includes metadata as a required field
- No UPDATE queries were found that could leave metadata in an invalid state
The change aligns with the system's design where metadata is always provided during token creation.

Ohayo sensei! Similar metadata condition issue as in token_balance.rs.
The SQL condition allows NULL metadata, but the struct TransferQueryResultRaw expects metadata to always be present.
Apply the same fix as suggested for token_balance.rs:
- "(t.metadata IS NULL OR length(t.metadata) > 0)".to_string(),
+ "(t.metadata IS NOT NULL AND length(t.metadata) > 0)".to_string(),269-271:
Same JSON parsing issue as in token_balance.rs.
Using .expect() for JSON parsing could cause runtime panics.
Apply the same error handling fix as suggested for token_balance.rs.

Consider using proper error handling for JSON parsing.
Using .expect() could cause runtime panics if the metadata is not valid JSON. Even if metadata is present, it might not be well-formed JSON.
Consider handling the JSON parsing error gracefully:
- let metadata: serde_json::Value =
- serde_json::from_str(&metadata_str).expect("metadata is always json");
+ let metadata: serde_json::Value = match serde_json::from_str(&metadata_str) {
+ Ok(value) => value,
+ Err(e) => {
+ warn!("Failed to parse metadata JSON: {}", e);
+ continue;
+ }
+ };Committable suggestion skipped: line range outside the PR's diff.

🛠️ Refactor suggestion
Add tests for metadata handling.
The change to non-optional metadata field requires comprehensive testing to ensure robustness.
Consider adding tests for:
- Valid metadata handling
- Invalid JSON metadata handling
- Edge cases (empty strings, very large metadata)
Would you like me to help create a test suite for these scenarios?
