Attention Indexers,

As part of the transition to the [Timeline Aggregation Protocol (TAP)](https://forum.thegraph.com/t/mainnet-release-of-tap-and-indexer-service-rs/6038), Indexers are being asked to migrate from Indexer Service (TypeScript) to Indexer Service (Rust).

**📅 The TypeScript version will be deprecated at the gateway level on December 4, 2024, at 9:00 AM (PST).**

This upgrade is essential for [enabling TAP](https://x.com/graphprotocol/status/1836094113978159457), among future protocol improvements. It will bring enhanced performance, scalability, and security to the indexing stack. Please complete the migration to the Rust-based Indexer Service before the deadline. Indexers who do not update before the December 4th deadline will not be eligible to serve queries.

📄 For more information and detailed instructions, access the [TAP migration guide](https://thegraph.com/docs/en/tap/), the [GitHub repository](https://github.com/graphprotocol/indexer-rs), or view the [Launchpad support documentation](https://github.com/graphops/launchpad-charts/blob/0f34816d7cafb132bdb755e646d2d659b174cbff/charts/graph-network-indexer/README.md).

If you have any questions or encounter any issues during the process, please visit the #indexer-software channel or message @gustavo on The Graph [Discord](https://discord.com/invite/graphprotocol) for assistance.

Thank you for your cooperation as we continue to improve The Graph ecosystem.
