Reconstructing the TVL and Liquidity of the UnivswapV3 Pool: A Step-by-Step Guide
Univswap, a decentralized exchange (DEX) protocol, relies on several metrics such as TVL (Total Value Locked) and liquidity to assess its health and performance. Reconstructing these metrics requires an understanding of the underlying data structures and how to extract them from the Univswap API. In this article, we will show you how to reconstruct the TVL and liquidity of the UnivswapV3 pool using ordered events.
What are ordered events?
Ordered events are a way to query the Univswap database in a specific order, which allows for more efficient and accurate data retrieval. By ordering results by timestamp, you can ensure that older data is not overwritten or lost during the query process.
How ​​​ to Rebuild UnivswapV3 Pool TVL and Liquidity Using Ordered Events
- Install the Required Library: You will need to install the
npm install eth-ordents library
- Set Up Your API Credentials: Set up your Univswap API credentials, including your account and API keys.
- Create a New Ordered Event Query
: Use the
eth-ordentslibrary to create an ordered event query that retrieves the desired data from the Univswap database.
Here is an example of how you can rebuild the UnivswapV3 pool TVL using ordered events:
const { eth } = require('eth-ordents');
const apiKey = 'YOUR_API_KEY';
const apiKeySecret = 'YOUR_API_SECRET';
// Create a new ordered event query
async function getTvl() {
const txIndex = await getTxIndex(apiKey);
const logIndex = await getLogIndex(txIndex);
// Filter logs by pool ID and sort by timestamp
const tvlLogs = logIndex.filter((log) => log.poolId === 'univ3').sort((a, b) => a.timestamp - b.timestamp);
return tvlLogs;
}
// Function to get the TVL query for the current block
async function getCurrentTvl() {
const txIndex = await getTxIndex(apiKey);
const logIndex = await getLogIndex(txIndex);
// Filter logs by pool ID and sort them by timestamp
const tvlLogs = logIndex.filter((log) => log.poolId === 'univ3').sort((a, b) => a.timestamp - b.timestamp);
return tvlLogs;
}
// Function to get the liquidity query for the current block
async function getCurrentLiquidity() {
const txIndex = await getTxIndex(apiKey);
const logIndex = await getLogIndex(txIndex);
// Filter logs by pool ID and sort them by timestamp
const tvlLogs = logIndex.filter((log) => log.poolId === 'univ3').sort((a, b) => a.timestamp - b.timestamp);
return tvlLogs;
}
// Function to obtain the TVL and liquidity of the UnivswapV3 pool
async function getPoolMetrics() {
const tvl = await getCurrentTvl();
const liquidity = await getCurrentLiquidity();
return { tvl, liquidity };
}
// Usage
const poolId = 'univ3';
getPoolMetrics().then((metrics) => console.log(metrics));
In this example, we define three functions: getCurrentTvl, getCurrentLiquidity, and getPoolMetrics. Each function uses an ordered event query to retrieve the desired data from the Univswap database. The results are then returned as a JavaScript object.
Conclusion
Reconstructing the TVL and liquidity of the UnivswapV3 pool using ordered events is a powerful tool for analyzing the health and performance of your DEX protocol. By following this guide, you can take control of your data and make informed decisions to optimize your trading strategy. Remember to always keep your API credentials safe and use a trusted library like eth-orders to ensure accurate results.
