Create deposit addresses

Generate unique deposit addresses for depositing assets to your Polymarket wallet.

How it works:

1. Submit your Polymarket wallet address
2. Receive deposit addresses for each blockchain type (EVM, Solana, Bitcoin)
3. Send assets from any supported chain to the appropriate deposit address
4. Assets are automatically bridged and swapped to USDC.e on Polygon
5. USDC.e is credited to your Polymarket wallet for trading

Supported Assets: Use /supported-assets to see all available chains and tokens you can deposit from.
