# Create withdrawal addresses

> Generate unique deposit addresses for withdrawing USDC.e from your Polymarket wallet to any supported chain and token.

<Card>
**⚠️ Important:** Do not pre-generate withdrawal addresses. Only generate them when you are ready to execute the withdrawal. Each address is configured for a specific destination.
</Card>

**How it works:**
1. Specify your Polymarket wallet address, destination chain, token, and recipient address
2. Receive deposit addresses for each blockchain type (EVM, Solana, Bitcoin)
3. Send USDC.e from your Polymarket wallet to the appropriate deposit address
4. Funds are automatically bridged and swapped to your desired token
5. Funds arrive at your destination wallet

**Supported Destinations:**
Use `/supported-assets` to see all available chains and tokens you can withdraw to.
