| This pull request has been automatically generated by downloading chain | |
| specifications from various JSON-RPC endpoints and extracting their checkpoints. | |
| Keep in mind that introducing a malicious checkpoint can redirect users to the wrong | |
| chain. If this pull request looks suspicious, please be cautious. | |
