Riskophobe Subgraph

This repository contains the Graph Protocol subgraph for the Riskophobe protocol. The subgraph indexes on-chain data related to Riskophobe's decentralized options trading, making it easily queryable via GraphQL. It provides a backend data layer for seamless integration with the Riskophobe dApp.

---

Overview

The Riskophobe Subgraph is designed to index and expose critical data points, including:

• Offer Creation: Tracks new option offers created on-chain.
• Token Transactions: Logs token purchases, returns, and collateral events.
• Fee Collection: Captures fees accrued by offer creators.
• Event History: Provides a comprehensive history of protocol interactions.

By leveraging The Graph, this repository ensures a fast and reliable way to fetch and display data for users of the Riskophobe dApp.

Prerequisites

Ensure you have the following installed:

• Node.js (version 16 or higher)
• npm or yarn
• Graph CLI

---

Installation

Clone the Repository

# Clone the repository
$ git clone https://github.com/BenAzlay/riskophobe-subgraph.git

# Navigate into the project directory
$ cd riskophobe-subgraph

Install Dependencies

# Using npm
$ npm install

# Or using yarn
$ yarn install

---

Development

Code Generation

The Riskophobe Subgraph uses the ABI of the Riskophobe smart contract to generate GraphQL schema types. To generate the necessary files, run:

# Generate code for the subgraph
$ npm run codegen

# Or using yarn
$ yarn codegen

Build the Subgraph

To compile the subgraph and ensure there are no errors:

# Build the subgraph
$ npm run build

# Or using yarn
$ yarn build

Deploy the Subgraph

1. Update the subgraph.yaml file with the appropriate network and contract address.
2. Authenticate with The Graph using the Graph CLI:

   $ graph auth --product hosted-service <ACCESS_TOKEN>

3. Deploy the subgraph:

   # Deploy to The Graph's hosted service
   $ npm run deploy
   
   # Or using yarn
   $ yarn deploy

Querying the Subgraph

After deployment, you can query the subgraph using any GraphQL client. For example, with graphql-request:

import { request, gql } from 'graphql-request';

const endpoint = 'https://api.studio.thegraph.com/query/27003/riskophobe-base/version/latest';

const query = gql`
  {
    offers {
      id
      creator
      collateralToken
      soldToken
      soldTokenAmount
      exchangeRate
    }
  }
`;

request(endpoint, query).then((data) => console.log(data));
