The Graph Foundation has set dates for Base, the second phase of moving Subgraphs that live only in Subgraph Studio onto The Graph Network. They were given in the summary of Graph Office Hours #283, posted on The Graph's forum on 10 November 2026.
Phase 1 covered BNB Smart Chain and Polygon (earlier post). According to the summary, more than 860 BSC and Polygon Subgraphs moved from Studio to the network with no major problems, and that infrastructure has been removed from the upgrade Indexer.
Timeline for Base
- 17 November 2026: the announcement goes to developers, and the curation bot used in Phase 1 starts signalling on Base Subgraphs.
- 1 December 2026: deadline for developers to publish Base Subgraphs that exist only in Studio.
- 1 to 15 December 2026: the Foundation keeps adding signal for late publishers, then ends Base support on the upgrade Indexer.
- By 15 December 2026: all Base Subgraphs should be on the network.
What it means
Builders: a Base Subgraph that exists only in Studio should be published to the network by 1 December. After 15 December the upgrade Indexer will no longer serve Base.
Indexers: the Foundation asks Indexers to plan Base infrastructure now, because Base is a large chain and has raised its block rate. It asks them to contact the Foundation before scaling up. The list of Subgraphs to cover will be posted in the #indexer-announcements channel after launch. New, curated Base Subgraphs give Indexers more to index, which matters while the reward eligibility rule raises the number of Subgraphs larger Indexers must serve.
Delegators: nothing to do directly. How well an Indexer handles the new Base load may affect its rewards.
Indexers and their stake are on BitBasic's The Graph dashboard.
