+# SubQuery - Multi-Chain. Example project for Kava (both Ethereum and Cosmos Co-Chains)
+
+[SubQuery](https://subquery.network) is a fast, flexible, and reliable open-source data indexer that provides you with custom APIs for your web3 project across all of our supported networks. To learn about how to get started with SubQuery, [visit our docs](https://academy.subquery.network).
+
+**This SubQuery project indexes both transactions and approvals of [USDT](https://kavascan.com/token/0x919C1c267BC06a7039e03fcc2eF738525769109c/token-transfers) on Kava EVM Network and all sent transfers from Kava Cosmos Co-chain**
+
+## Start
+
+First, install SubQuery CLI globally on your terminal by using NPM `npm install -g @subql/cli`
+
+You can either clone this GitHub repo, or use the `subql` CLI to bootstrap a clean project in the network of your choosing by running `subql init` and following the prompts.
+
+Don't forget to install dependencies with `npm install` or `yarn install`!
+
+## Editing your SubQuery project
+
+Although this is a working example SubQuery project, you can edit the SubQuery project by changing the following files:
+
+- The project manifest in `project.ts` defines the key project configuration and mapping handler filters
+- The GraphQL Schema (`schema.graphql`) defines the shape of the resulting data that you are using SubQuery to index
+- The Mapping functions in `src/mappings/` directory are typescript functions that handle transformation logic
+
+SubQuery supports various layer-1 blockchain networks and provides [dedicated quick start guides](https://academy.subquery.network/quickstart/quickstart.html) as well as [detailed technical documentation](https://academy.subquery.network/build/introduction.html) for each of them.
+
+## Run your project
+
+_If you get stuck, find out how to get help below._
+
+The simplest way to run your project is by running `yarn dev` or `npm run-script dev`. This does all of the following:
+
+1.  `yarn codegen` - Generates types from the GraphQL schema definition and contract ABIs and saves them in the `/src/types` directory. This must be done after each change to the `schema.graphql` file or the contract ABIs
+2.  `yarn build` - Builds and packages the SubQuery project into the `/dist` directory
+3.  `docker-compose pull && docker-compose up` - Runs a Docker container with an indexer, PostgeSQL DB, and a query service. This requires [Docker to be installed](https://docs.docker.com/engine/install) and running locally. The configuration for this container is set from your `docker-compose.yml`
+
+You can observe the three services start, and once all are running (it may take a few minutes on your first start), please open your browser and head to [http://localhost:3000](http://localhost:3000) - you should see a GraphQL playground showing with the schemas ready to query. [Read the docs for more information](https://academy.subquery.network/run_publish/run.html) or [explore the possible service configuration for running SubQuery](https://academy.subquery.network/run_publish/references.html).
+
+## Query your project
+
+For this project, you can try to query with the following GraphQL code to get a taste of how it works.
+
+```graphql
+query {
+  transactions {
+    nodes {
+      id
+      value
+      to
+      from
+      contractAddress
+    }
+  }
+  approvals {
+    nodes {
+      id
+      value
+      owner
+      spender
+      contractAddress
+    }
+  }
+  transfers {
+    nodes {
+      id
+      blockHeight
+      txHash
+      fromAddress
+      toAddress
+      amount
+      denomination
+    }
+  }
+}
+```
+
+You can explore the different possible queries and entities to help you with GraphQL using the documentation draw on the right.
+
+## Publish your project
+
+SubQuery is open-source, meaning you have the freedom to run it in the following three ways:
+
+- Locally on your own computer (or a cloud provider of your choosing), [view the instructions on how to run SubQuery Locally](https://academy.subquery.network/run_publish/run.html)
+- By publishing it to our enterprise-level [Managed Service](https://managedservice.subquery.network), where we'll host your SubQuery project in production ready services for mission critical data with zero-downtime blue/green deployments. We even have a generous free tier. [Find out how](https://academy.subquery.network/run_publish/publish.html)
+- [Coming Soon] By publishing it to the decentralised [SubQuery Network](https://subquery.network/network), the most open, performant, reliable, and scalable data service for dApp developers. The SubQuery Network indexes and services data to the global community in an incentivised and verifiable way
+
+## What Next?
+
+Take a look at some of our advanced features to take your project to the next level!
+
+- [**Multi-chain indexing support**](https://academy.subquery.network/build/multi-chain.html) - SubQuery allows you to index data from across different layer-1 networks into the same database, this allows you to query a single endpoint to get data for all supported networks.
+- [**Dynamic Data Sources**](https://academy.subquery.network/build/dynamicdatasources.html) - When you want to index factory contracts, for example on a DEX or generative NFT project.
+- [**Project Optimisation Advice**](https://academy.subquery.network/build/optimisation.html) - Some common tips on how to tweak your project to maximise performance.
+- [**GraphQL Subscriptions**](https://academy.subquery.network/run_publish/subscription.html) - Build more reactive front end applications that subscribe to changes in your SubQuery project.
