# Deposit for Polymarket

> Find the one address that funds your Polymarket trading, learn which coin it takes, and fill it from an exchange or from the money already in your wallet.

Polymarket orders do not use your main wallet. They draw on a separate **Polymarket deposit wallet** that belongs to your account, and it accepts one thing only: **pUSD on Polygon**. Get that right and funding takes a couple of minutes.

## Find your Polymarket deposit address

**1. Open the Deposit sheet**

Click **Deposit** in the top bar, then **Deposit** under your wallet total.

**2. Choose the Polymarket tab**

The sheet shows your Polymarket deposit address, a QR code and the line "Send pUSD on this network: Polygon".

**3. Copy the address**

Use the copy button rather than retyping it. You can also ask the chat "What is my Polymarket deposit address?".

The Polymarket tab of the Deposit sheet

If the tab says "Set up your agent first to get a Polymarket deposit address", your account key is still being created, which happens on its own right after sign-up. Close the sheet and open it again in a moment; [External AI](https://docs.openfinance.tech/product/external-ai.md) shows the key once it is ready.

## Fund it

There are two ways in, depending on where your money is now.

> [tab] From an exchange or another wallet
>
> Send **pUSD on Polygon** to the Polymarket deposit address. Nothing else: not USDC on another chain, not USDT. Funds on the wrong network or token cannot be recovered.

> [tab] From your OpenFinance wallet
>
> Ask the agent to move funds you already hold, for example:
>
> ```text theme={"system"}
> Fund my Polymarket deposit wallet with 50 dollars from my wallet. Show me the summary first.
> ```
>
> The agent routes and converts as needed and shows a summary. Nothing is sent until you confirm. If some funds arrive as USDC.e, ask it to convert them to pUSD; the conversion is 1 to 1.

## Check it arrived

Ask "What is my Polymarket balance?". The agent reports what is ready to trade in your deposit wallet. Then head to [Polymarket](https://docs.openfinance.tech/markets/polymarket.md) to place your first order.

The agent confirms what is ready to trade

> [!NOTE]
>
> The first time you open External AI, a one-time notice reminds you to send only pUSD to Polymarket. It is the same rule as above, shown once so it sticks.
