Ethereum: How to rebuild TVL and liquidity of UnivswapV3 pool through ordered events?

Reconstructing UnivswapV3 Pool TVL and Liquidity Through Ordered Events:

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

Univswap, a decentralized exchange (DEX) protocol, relies on several metrics such as TVL (Total Value Locked) and liquidity to measure its health and performance. Reconstructing these metrics requires understanding the underlying data structures and extracting them from Univswap’s API. In this article, we will show you how to reconstruct UnivswapV3 pool TVL and liquidity through ordered events.

What are the ordered events?

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

Reconstructing UnivswapV3 Pool TVL and Liquidity via Ordered Transactions

• Install Required Library: You need to install the eth-ordents' library, which provides an interface for ordering transactions on the Ethereum blockchain.

npm install eth-orders

• Create a New Ordered Transaction Query: Use the eth-ordents’ library to create an ordered transaction query that retrieves the desired data from the Univswap database.

Here is an example of how you can reconstruct UnivswapV3 pool TVL using ordered transactions:

const { eth } = require ( ' eth - order ' ) ;
const apiKey = 'YOUR_API_KEY';
const APIKeySecret = 'YOUR_API_SECRET';
// Create a new subscribed event query
async function getTvl() { .
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 TVL query for 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 liquidity query for 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 get TVL and liquidity of 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 transaction query to retrieve the desired information from the Univswap database. The results are then returned as a JavaScript object.

Conclusion

Reconstructing the TVL and liquidity of a UnivswapV3 pool using ordered transactions 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. Always remember to keep your API credentials secure and use a reputable library like “eth-orders” to ensure accurate results.
