How to get Uniswap V2 pair address


Before getting started, make sure you have the following ready:

  • Node v.14+ or Python
  • NPM/Yarn or Pip

Step 1: Setup Moralis

First register your Moralis account and get your Moralis API Key.

Once you have your Moralis API Key, install the Moralis SDK in your project.

npm install moralis @moralisweb3/common-evm-utils

Step 2: Get Pair Address 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 three parameters: token0, token1 and address.

Once you've obtained all three parameters, 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 chain = EvmChain.ETHEREUM;

// token 0 address, e.g. WETH token address
const token0Address = "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2";

// token 1 address, e.g. LINK token address
const token1Address = "0x514910771AF9Ca656af840dff83E8264EcF986CA";

const response = await Moralis.EvmApi.defi.getPairAddress({



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:

"token0": {
"address": "0x514910771af9ca656af840dff83e8264ecf986ca",
"name": "Chain Link",
