Bridge & Funding

The polygolem bridge family wraps Polymarket’s Bridge API. Use it to discover supported chains, request a quote, and create a deposit address that the bridge will sweep into Polygon-native USDC.

Supported assets

Terminal window
polygolem bridge assets
{
  "assets": [
    { "chain": "ethereum", "symbol": "USDC", "decimals": 6 },
    { "chain": "arbitrum", "symbol": "USDC", "decimals": 6 },
    { "chain": "base",     "symbol": "USDC", "decimals": 6 }
  ]
}

Get a quote

Estimate fees and expected pUSD on the receiving side:

Terminal window
polygolem bridge quote \
  --from-chain base \
  --from-asset USDC \
  --amount 50.00
{
  "from_amount": "50.00",
  "to_amount":   "49.92",
  "fee":         "0.08",
  "estimated_seconds": 90
}

Create a deposit address

The bridge issues a one-shot address scoped to your destination wallet. Send USDC to this address from the chosen source chain, and the bridge sweeps it to Polygon:

Terminal window
polygolem bridge deposit-address \
  --address 0xYourPolygonAddress \
  --from-chain base \
  --from-asset USDC
{
  "deposit_address": "0x...",
  "expires_at":      1746628800,
  "chain":           "base",
  "asset":           "USDC"
}

Check deposit status

After you send funds, poll for sweep state:

Terminal window
polygolem bridge deposit-status --deposit-address 0x...
{
  "status": "completed",
  "tx_hash": "0x...",
  "amount":  "49.92"
}

What’s next after bridging

The deposit wallet flow is required for all trading:

Terminal window
POLYMARKET_PRIVATE_KEY="0x..." \
  polygolem deposit-wallet onboard --fund-amount 0.71
