How to get Uniswap V2 pair reserves

Step 1: Setup Moralis​

Read the article Setting Up Moralis: Getting Started and make sure to finish all the steps. Only after that you can go ahead to complete this guide.

Step 2: Get Pair Reserves of A Uniswap V2 Liquidity Pool​

In order to get pair address of a liquidity, Moralis provides you a getPairAddress endpoint to do so.

Here you'll need two parameters: pairAddress and address.

Once you've obtained the pairAddress and address, you can copy the following code:

const Moralis = require("moralis").default;
const { EvmChain } = require("@moralisweb3/common-evm-utils");

const runApp = async () => {
await Moralis.start({
apiKey: "YOUR_API_KEY",
// ...and any other configuration
});

const pairAddress = "0xa2107fa5b38d9bbd2c461d6edf11b11a50f6b974";

const chain = EvmChain.ETHEREUM;

const response = await Moralis.EvmApi.defi.getPairReserves({
pairAddress,
chain,
});

console.log(response.toJSON());
};

runApp();

Step 3: Run the script​

To run the script, enter the following command:

node index.js

In your terminal, you should see the following JSON response:

{
"reserve0": "153821290283758699698748",
"reserve1": "794388536599735508826"
}

Congratulations 🥳 You just get the pair reserves of a Uniswap V2 liquidity pool with just a few lines of code using the Moralis DeFi API!
