- Only EVM chains are supported. Currently no support for [Fuel](/docs/HyperIndex/fuel/fuel.md) chains.
- No [test framework](/docs/HyperIndex/testing) support.
- Only block number is provided in the block object. We'll definitely add more fields in the future.
- **Block handlers must be in or imported by a handler file referenced in `config.yaml`**. Standalone block handler files won't execute. See recommended approach below.

### Recommended Approach

To ensure your block handlers run properly, create an index handler file (e.g., `EventHandlers.ts`) and have all contracts point to this file in your `config.yaml`. Then import your other handler files, including block handler files, in this index file.

The PR should fix it, so I'm not sure whether we want to add this documentation section

@DZakh ok sweet can delete this then


#### Before
```yaml
# config.yaml
contracts:
- name: Contract1
handler: ./src/handlerFile1.ts
# ...
- name: Contract2
handler: ./src/handlerFile2.ts
# ...
```

#### After
```yaml
# config.yaml
contracts:
- name: Contract1
handler: ./src/EventHandlers.ts
# ...
- name: Contract2
handler: ./src/EventHandlers.ts
# ...
```

```typescript
// EventHandlers.ts
import "./handlerFile1";
import "./handlerFile2";
import "./blockHandlerFile";
```

This ensures that all your handlers, including block handlers, are properly registered and will execute.
