NEAR Lake Framework

We want to remind you that we've released NEAR Lake Framework. If you don't have a hard requirement to use NEAR Indexer Framework and run nearcore node for your indexer, we encourage you to migrate to NEAR Lake Framework.

NEAR Lake Framework allows you to build a lightweight indexer which doesn't require a lot of resources. This will:

• decrease your spending on infrastructure
• don't require updates on every nearcore release

Please, reach out to us if you have questions about migration, we will be happy to help.
