# How to query USDT0 data on Stable Chain using Ormi subgraphs

## Intro

This guide shows you how to index and query USDT0 on Stable using Ormi’s 0xGraph. By the end, you’ll have a live subgraph that tracks transfers, mints, burns and related events, and you’ll be able to query USDT0 activity with GraphQL.

## Prerequisites

* [An Ormi Labs account](https://app.ormilabs.com/)
* [Graph CLI installed](https://www.npmjs.com/package/@graphprotocol/graph-cli?ref=blog.ormilabs.com)
* [node.js installed](https://nodejs.org/en)
* [Git installed](https://git-scm.com/downloads)

## 1. Create and configure your subgraph project

### 1.1 Get your Ormi API key

1. Log in to [Ormi](https://app.ormilabs.com/) and go to your dashboard.
2. From the dashboard, create an API key for deployments.

</Frame>

Keep this page open, we will need the API key to deploy a subgraph.

### 1.2 Install Graph CLI

On your local machine, run the following in your terminal:

```bash theme={null}
npm install -g @graphprotocol/graph-cli
```

### 1.3 Create a directory for your subgraph

```bash theme={null}
mkdir usdt0-stable
cd usdt0-stable
```

We will call the folder `usdt0-stable` in this example.

### 1.4 Initialize the project

Run bash in the directory folder

```bash theme={null}
npm init -y
```

### 1.5 Install dependencies

```bash theme={null}
npm install --save-dev @graphprotocol/graph-ts
npm install --save-dev assemblyscript
```

### 1.6 Create the required files

You will need:

* subgraph.yaml
* schema.graphql
* mappings/USDT0.ts
* abis/USDT0.json

After creating these files, put them in the `usdt0-stable` folder.

#### Directory layout

```
usdt0-stable/
├─ abis/
│  └─ USDT0.json
│
├─ mappings/
│  └─ USDT0.ts
│
├─ schema.graphql
│
├─ subgraph.yaml
│
├─ generated/
│  ├─ schema.ts
│  └─ USDT0/
│     └─ USDT0.ts
│
├─ build/
│  └─ USDT0/
│     └─ USDT0.wasm
│
├─ node_modules/
```

You will also see `node_modules/` after installing dependencies - that is expected.

## 2. Build the Subgraph

Generate types:

```bash theme={null}
graph codegen
```

<Frame>
  <img src="https://mintcdn.com/ormilabs/2_HuVVq5g9vs03Oa/images/0xgraph/tutorials/ormi02.png?fit=max&auto=format&n=2_HuVVq5g9vs03Oa&q=85&s=0bdb531a7639e379821bff865ce5183c" alt="Run codegen" width="1244" height="443" data-path="images/0xgraph/tutorials/ormi02.png" />

  <figcaption>Run codegen</figcaption>
</Frame>

Now run:

```bash theme={null}
graph build
```

<Frame>
  <img src="https://mintcdn.com/ormilabs/2_HuVVq5g9vs03Oa/images/0xgraph/tutorials/ormi03.png?fit=max&auto=format&n=2_HuVVq5g9vs03Oa&q=85&s=3a7be7e8067b378ef0495a6ce4ce04f9" alt="Build graph" width="1153" height="372" data-path="images/0xgraph/tutorials/ormi03.png" />

  <figcaption>graph build</figcaption>
</Frame>

## 3. Deploy the Subgraph to Ormi

Return to your [API key](https://app.ormilabs.com/dashboard/api) from the dashboard. Replace `<graph-name>` and `<API key>` with your actual values

```bash theme={null}
graph deploy <graph-name> --node  https://subgraph.api.ormilabs.com/deploy --ipfs https://subgraph.api.ormilabs.com/ipfs --deploy-key <API key>
```

<Frame>
  <img src="https://mintcdn.com/ormilabs/2_HuVVq5g9vs03Oa/images/0xgraph/tutorials/ormi04.png?fit=max&auto=format&n=2_HuVVq5g9vs03Oa&q=85&s=a30518713da3429df6c9be00653f4365" alt="Deploy graph" width="1610" height="554" data-path="images/0xgraph/tutorials/ormi04.png" />

  <figcaption>graph deploy</figcaption>

### Track sync status

You can check syncing in the dashboard by going to the Subgraphs tab:

## 4. Query USDT0

Click on the button where the red arrow is pointing.

### Sample query

Run this query to fetch the latest transfers

```graphql theme={null}
{
  transfers(first: 10, orderBy: timestamp, orderDirection: desc) {
    id
    from {
      id
    }
    to {
      id
    }
    value
    blockNumber
    timestamp
    txHash
  }
}
```
