# Integrating USDC into Your Application

## Overview

:::info
This guide is maintained by [Circle](https://www.circle.com).
:::

This guide walks you through how to integrate **USDC** into your application using [Viem](https://viem.sh).

We'll demonstrate how to interact with the USDC token contract to enable key functionality such as reading balances, transferring funds, approving third-party spenders, monitoring transfer events, and optimizing contract reads.

You'll be using the [Public Client](/docs/clients/public) to read blockchain state and [Wallet Client](/docs/clients/wallet) to sign and send transactions.

We'll be working on the **Sepolia testnet**, but the steps apply to any USDC-supported EVM-compatible network.

By the end of this guide, you'll know how to:

* Set up Viem clients and securely manage accounts
* Read and display USDC balances
* Send USDC between wallets
* Approve contracts (e.g., Uniswap) to spend USDC on your behalf
* Monitor on-chain Transfer events in real-time
* Optimize data loading with batched readContract calls

Each step is self-contained and modular — designed to be easily copied into your own project, whether you're building a wallet, a dashboard, a DeFi tool, or anything else powered by stable digital dollars.

Let's get started.

## Steps

::::steps

### Set up Clients

In this step, we'll configure a **Public Client** for reading blockchain data, and a **Wallet Client** for signing and sending transactions with USDC. You'll also set up your account using a private key.

We'll be using the Sepolia testnet, but you can easily swap this for any EVM-compatible chain.

### Initialize the USDC Contract

Now we'll define the **USDC token contract** by providing its address and ABI. This allows us to interact with functions like balanceOf, transfer, and approve.

You can use any USDC address from [Circle's official registry](https://developers.circle.com/stablecoins/usdc-contract-addresses), but for this guide, we're using the Sepolia testnet version.

Note: USDC uses 6 decimals — unlike ETH which uses 18. Always remember to format your values accordingly.

### Transfer USDC

Now we'll transfer USDC from your wallet to another address. This is the most common action in USDC-based apps — whether it's sending payments, tipping, or moving funds between accounts.
