Onboarding Checklist

Please complete the following:

1. Set up a subquery indexer (e.g. Goldsky Subgraph)
   1. Follow the docs here: https://docs.goldsky.com/guides/create-a-no-code-subgraph
   2. General Steps
      1. create an account at app.goldsky.com
      2. deploy a subgraph or migrate an existing subgraph - https://docs.goldsky.com/subgraphs/introduction
      3. Use the slugs linea-testnet and linea when deploying the config
2. Prepare Subquery query code according to the Data Requirement section below.
3. Submit your response as a Pull Request to: https://github.com/delta-hq/l2-lxp-liquidity-reward
   1. With path being /<your_protocol_handle>
4. Submit your contract addresses through this Form

Data Requirement

Goal: Hourly snapshot of TVL by User by Asset

For each protocol, we are looking for the following:

1. Query that fetches all relevant events required to calculate User TVL in the Protocol at hourly level.
2. Code that uses the above query, fetches all the data and converts it to csv file in below given format.

Teams can refer to the example we have in there to write the code required.

Output Data Schema

Data Field	Notes
block_number
timestamp
user_address
token_address
token_symbol (optional)	Symbol of token
token_balance	Balance of token (If the token was borrowed, this balance should be negative)
usd_price (from oracle)	Price of token (optional)

Sample output row will look like this:

blocknumber	timestamp	user_address	token_address	token_symbol (optional)	token_balance
2940306	2024-03-16 19:19:57	0x4874459FE…d689	0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2	WETH	100

Note: Expect multiple entries per user if the protocols has more than one token asset

Query Example (DEX - CL MM)

Below is the query being used in the example we have in the repo link. For querying like this, please create a subgraph that has this data for your respective protocol. This data should be further transformed to get the data as per required Output schema.

Adapter Example

In this repo, there is an adapter example. This adapter aims to get data positions from the subrgaph and calculate the TVL by users. The main scripts is generating a output as CSV file.

Adapter Example

How to execute this project?

npm install // install all packages
npm run watch //other terminal tab
npm run start // other terminal tab

By this, we'll be able to generate the output csv file.
