Reconstructing the TVL and Liquidity of a UnivswapV3 Pool: A Step-by-Step Guide

Univswap, a decentralized exchange (DEX) protocol, relies on various metrics such as TVL (Total Value Locked) and liquidity to assess its health and performance. Reconstructing these metrics requires understanding 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 a UnivswapV3 pool using ordered events.

What are ordered events?

Ordered events are a way of querying the Univswap database in a specific order, allowing for more efficient and accurate data retrieval. By sorting the results by timestamp, you can ensure that older data is not overwritten or lost during the query process.

How ​​to reconstruct UnivswapV3 Pool TVL and liquidity via ordered events

• Install the required library: You will need to install the eth-ordents library, which provides an interface for ordering events on the Ethereum blockchain.

npm install eth-ordents

• Configure your API credentials

  : Set up your Univswap API credentials, including your account and API keys.

• Create a new ordered event query: Use the eth-ordents library to create an ordered event query that retrieves the desired data from the Univswap database.

Here is an example of how you can reconstruct the TVL of a UnivswapV3 pool using ordered events:

const { eth } = require('eth-ordens');
const apiKey = 'YOUR_API_KEY';
const apiKeySecret = 'YOUR_API_SECRET';
// Create a new query on the edited event
asynchronous function getTvl() {
const txIndex = await getTxIndex(apiKey);
const logIndex = await getLogIndex(txIndex);
// Filter the records 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 TVL query for the current block
asynchronous function getCurrentTvl() {
const txIndex = await getTxIndex(apiKey);
const logIndex = await getLogIndex(txIndex);
// Filter the records 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
asynchronous function getCurrentLiquidity() {
const txIndex = await getTxIndex(apiKey);
const logIndex = await getLogIndex(txIndex);
// Filter the records 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 TVL and liquidity of UnivswapV3 pool
asynchronous 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 a structured 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 structured 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 reputable library like eth-ordens to ensure accurate results.
