Polymarket uses pUSD (Polymarket USD) on Polygon as collateral for all trading. The Bridge API lets you deposit assets from Ethereum, Solana, Bitcoin, and other chains—they’re automatically converted to pUSD on Polygon.

​
How It Works

  1. Request bridge addresses for your Polymarket wallet
  2. Send assets to the appropriate address for your source chain
  3. Assets are bridged and swapped to pUSD automatically
  4. pUSD is credited to your wallet for trading

​
Create Bridge Addresses

Generate unique bridge addresses linked to your Polymarket wallet. See Create bridge addresses for the full request and response schemas.
Builders: attach your code. If you route user funds through this endpoint, pass your builder code via the optional X-Builder-Code header (bytes32 hex; 0x + 64 hex chars). It lets our bridge provider attribute traffic to your app, so stuck or delayed transfers can be traced and prioritized. The header is optional. Requests without it still succeed but return a missing_builder_code warning, and a malformed code returns 400. Get your code at Settings → Builder.
The response returns one bridge address per address type (evm, svm, btc, tvm). Send from the matching source chain to the matching address.

​
Address Types

Each address is unique to your wallet. Only send assets from supported chains to the correct address type.

​
Deposit Flow

1

Get Your Bridge Address

Call POST /deposit with your Polymarket wallet address to get bridge addresses.
2

Check Supported Assets

Verify your token is supported and meets the minimum deposit amount via /supported-assets.
3

Send Assets

Transfer tokens to the appropriate bridge address from your source chain.
4

Track Status

Monitor your deposit progress using /status/{address}.

​
USDC vs pUSD

You can deposit either USDC (native) or USDC.e (bridged) as the source asset to your Polymarket wallet. Either way, the incoming USDC or USDC.e is wrapped into pUSD via the Collateral Onramp, and pUSD is what you hold and trade with on Polymarket.

​
Large Deposits

For deposits over $50,000 originating from a chain other than Polygon, we recommend using a third-party bridge to minimize slippage: Bridge directly to your Polymarket USDC (Polygon) bridge address. Polymarket is not affiliated with or responsible for any third-party bridge.

​
Minimum Deposits

Each asset has a minimum deposit amount. Deposits below the minimum will not be processed. Check /supported-assets for current minimums.

​
Deposit Recovery

If you deposited the wrong token, use this tool to recover your funds: recovery.polymarket.com
Sending unsupported tokens may cause irrecoverable loss. Always verify your token is listed in Supported Assets before depositing.
