Description

This project is a subgraph designed to query the USDC/USDM Liquidity pool using Curve Finance on Polygon. It is built using The Graph protocol, a decentralized protocol for indexing and querying data from blockchains. This is deployed in Polygon Mainnet

Installation

To install and set up the project, follow the steps below:

1. Clone the repository:

   git clone https://github.com/Tropykus/tropykus-v2-usdm-c-curve-pool
   cd tropykus-v2-usdm-c-curve-pool

2. Install the dependencies:

   yarn install 

3. Authenticate with The Graph Studio:

   graph auth --studio <your-auth-key>

4. Generate the code and build the project:

   graph codegen && graph build

5. Deploy the project:

   graph deploy --studio tropykus-v2-usdm-c-curve-pool

Usage

Once the project is installed and deployed, you can run queries like the one below:

query SwapsByUser($user: String) {
    tokenExchanges(where: { buyer: $user }) {
        tokens_sold
        tokens_bought
        transactionHash
        blockTimestamp
        buyer
        sold_token{
          id
          symbol
          decimals
        }
       bought_token{
        id
        decimals
        symbol
      }
    transactionHash
    blockTimestamp
    }
}

To get the bruteDeposits of a user you can use:

query UserActivity($user: String)  {
  userActivities(where: {id: $user}) {
    id
    bruteDeposits
    cleanDepositsTimestamp
    depositsAfterCleanTimestamp
    withdrawsAfterCleanTimestamp
  }
}

The variables should be like this:

{
  "user": "0x1234..."
}

Updating liquidity pools

In order to update the liquidity pools go check the parameters of networks.staging.json (or production.staging.json)

{
  "network": "matic",
  "address": "0xcD4e41382940F46c2ba7291364b43FdA0F5C2B02",
  "startBlock": 52486279
}

Then run the command npm run build:staging

It should update the subgraph.yaml file automatically

# ...
dataSources:
  - kind: ethereum
    name: CurveStableSwapNG
    network: matic
    source:
      address: "0xcD4e41382940F46c2ba7291364b43FdA0F5C2B02"
      abi: CurveStableSwapNG
      startBlock: 52486279

Authenticate with The Graph Studio: graph auth --studio <your-auth-key>

Generate the code and build the project: npm run build:staging

Deploy the project: npm run deploy:staging
