+# Goldsky subgraphs
+Subgraphs have been migrated to Goldsky, more contracts may follow (we may need to evaluate which subgraphs are still needed).
+For old subgraphs please refer to the [legacy repository](https://github.com/bobanetwork/boba/tree/develop/packages/boba/subgraph).
+
+## Install GoldSky
+`curl https://goldsky.com | sh`
+
+or refer to the official documentation: https://docs.goldsky.com/introduction
+
+Hint: You can also directly migrate your already deployed subgraphs from The Graph to GoldSky.
+
+## Configuration
+With GoldSky you only need to add your ABI into the `./abi` folder and create a configuration file (refer to `lightbridge.json`).
+
+Here is also some official [GoldSky documentation](https://docs.goldsky.com/subgraphs/introduction).
+
+To deploy your subgraphs execute:
+`goldsky subgraph deploy {NAME_OF_SUBGRAPH}/v{VERSION} --from-abi ./{YOUR_CONFIG_JSON}.json`
+
+Here is an example:
+`goldsky subgraph deploy light-bridge/v1 --from-abi ./lightbridge.json`
+
+## API / Account
+We already have a GoldSky account. As of 18. Dec 23 following people have already access that you can reach out to for access:
+- Boyuan
+- Souradeep
+- Kevin
+
+## Online dashboard
+You can view your subgraphs [here](https://app.goldsky.com/dashboard/subgraphs).
+This dashboard also gives you access to your subgraphs directly, so that you can test out queries.
+
+## Queries
+GoldSky already generates GraphQL types for, that you can use in your queries (which make your querying much more powerful and easier).
+
+An example:
+
+```graphql
+query Teleportation($wallet: String!, $sourceChainId: BigInt!) {
+  assetReceiveds(
+    where: {and: [{emitter_contains_nocase: $wallet}, { sourceChainId: $sourceChainId }]}
+  ) {
+    token
+    sourceChainId
+    toChainId
+    depositId
+    emitter
+    amount
+    block_number
+    timestamp_
+    transactionHash_
+  }
+}
+```
+
+- `emitter_contains_nocase` is a non-standard operation, most GraphQL providers don't support case insensitive querying.
+- `block_number`, `timestamp_`, `transactionHash_` and many others are indexed/queryable as well, despite not being part of the on-chain event.
