How to get Uniswap V3 pair address

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 Address of A Uniswap V3 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:

index.js (JavaScript)

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({
    token0Address,
    token1Address,
    chain,
    exchange: "uniswapv3",
  });

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

runApp();

index.ts (TypeScript)

import Moralis from "moralis";
import { EvmChain } from "@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({
    token0Address,
    token1Address,
    chain,
    exchange: "uniswapv3",
  });

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

runApp();

index.py (Python)

from moralis import evm_api

api_key = "YOUR_API_KEY"

params = {
    "exchange": "uniswapv3",
    # token 0 address, e.g. WETH token address
    "token0_address": "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2",
    # token 1 address, e.g. LINK token address
    "token1_address": "0x514910771AF9Ca656af840dff83E8264EcF986CA",
    "chain": "eth"
}

result = evm_api.defi.get_pair_address(
    api_key=api_key,
    params=params,
)

print(result)

Step 3: Run the script

To run the script, enter the following command:

Shell (JavaScript)

node index.js

Shell (TypeScript)

ts-node index.ts

Shell (Python)

python index.py

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

{
  "token0": {
    "address": "0x514910771af9ca656af840dff83e8264ecf986ca",
