 No. Once a subgraph is created, the name cannot be changed. Make sure to think of this carefully before you create your subgraph so it is easily searchable and identifiable by other dapps.

+## 4. Am I still able to create a subgraph if my smart contracts don't have events?
 
 It is highly recommended that you structure your smart contracts to have events associated with data you are interested in querying. Event handlers in the subgraph are triggered by contract events and are by far the fastest way to retrieve useful data.
 
-If the contracts you are working with do not contain events, your subgraph can use call and block handlers to trigger indexing. Although this is not recommended, as performance will be significantly slower.

+## 5. How are templates different from data sources?
 
 Templates allow you to create data sources on the fly, while your subgraph is indexing. It might be the case that your contract will spawn new contracts as people interact with it, and since you know the shape of those contracts (ABI, events, etc) upfront you can define how you want to index them in a template and when they are spawned your subgraph will create a dynamic data source by supplying the contract address.
 
 Check out the "Instantiating a data source template" section on: [Data Source Templates](/developing/creating-a-subgraph#data-source-templates).

+## 10. What is the recommended way to build "autogenerated" ids for an entity when handling events?
 
 If only one entity is created during the event and if there's nothing better available, then the transaction hash + log index would be unique. You can obfuscate these by converting that to Bytes and then piping it through `crypto.keccak256` but this won't make it more unique.

 Within a subgraph, the events are always processed in the order they appear in the blocks, regardless of whether that is across multiple contracts or not.

 Yes. Sepolia supports block handlers, call handlers and event handlers. It should be noted that event handlers are far more performant than the other two handlers, and they are supported on every EVM-compatible network.

 Yes. `dataSources.source.startBlock` in the `subgraph.yaml` file specifies the number of the block that the data source starts indexing from. In most cases, we suggest using the block in which the contract was created: [Start blocks](/developing/creating-a-subgraph#start-blocks)

 Yes! Try the following command, substituting "organization/subgraphName" with the organization under it is published and the name of your subgraph:

 You have to redeploy the subgraph, but if the subgraph ID (IPFS hash) doesn't change, it won't have to sync from the beginning.

 Federation is not supported yet, although we do want to support it in the future. At the moment, something you can do is use schema stitching, either on the client or via a proxy service.

 By default, query responses are limited to 100 items per collection. If you want to receive more, you can go up to 1000 items per collection and beyond that, you can paginate with:
 
 ```graphql

+## 22. If my dapp frontend uses The Graph for querying, do I need to write my query key into the frontend directly? What if we pay query fees for users – will malicious users cause our query fees to be very high?
 
 Currently, the recommended approach for a dapp is to add the key to the frontend and expose it to end users. That said, you can limit that key to a hostname, like _yourdapp.io_ and subgraph. The gateway is currently being run by Edge & Node. Part of the responsibility of a gateway is to monitor for abusive behavior and block traffic from malicious clients.

-If you’re a subgraph developer, you can deploy a new version of your subgraph to Subgraph Studio using the CLI. It’ll be private at that point, but if you’re happy with it, you can publish to the decentralized Graph Explorer. This will create a new version of your subgraph that Curators can start signaling on.

+## 24. In what order are the event, block, and call handlers triggered for a data source?
 
 Event and call handlers are first ordered by transaction index within the block. Event and call handlers within the same transaction are ordered using a convention: event handlers first then call handlers, each type respecting the order they are defined in the manifest. Block handlers are run after event and call handlers, in the order they are defined in the manifest. Also these ordering rules are subject to change.
