Bridge API

Production Bridge API: https://bridge.polymarket.com.

The Bridge API is HTTP-only in polygolem. It does not sign messages and does not use CLOB L2 or relayer credentials. The bridge converts incoming supported assets into pUSD credited to the destination Polymarket wallet.

Polygolem Surface

Surface	Coverage
`pkg/bridge`	Supported assets, deposit addresses, deposit status, quotes
`polygolem bridge assets`	`GET /supported-assets`
`polygolem bridge deposit address`	`POST /deposit`

pkg/bridge exposes more than the current CLI. Quote and status polling are SDK-only until CLI commands are added.

REST Mapping

Polygolem method	REST path	Auth	Notes
`GetSupportedAssets`	`GET /supported-assets`	Public	Returns chains, token contracts, decimals, and minimum checkout USD
`CreateDepositAddress`	`POST /deposit`	Public	Body: `{ "address": "0x..." }`; response includes EVM, SVM, and BTC deposit addresses
`GetDepositStatus`	`GET /status/{address}`	Public	Polls bridge-observed transactions for a deposit address
`GetQuote`	`POST /quote`	Public	Estimates output and fees for a source token/chain and destination token/chain

Request Shapes

Create a deposit address:

{
  "address": "0xYourPolymarketWallet"
}

Quote a bridge move:

{
  "fromAmountBaseUnit": "50000000",
  "fromChainId": "8453",
  "fromTokenAddress": "0x...",
  "recipientAddress": "0xYourPolymarketWallet",
  "toChainId": "137",
  "toTokenAddress": "0xC011a7E12a19f7B1f670d46F03B03f3342E82DFB"
}

toTokenAddress should be pUSD for the canonical V2 flow. pUSD is the token the CLOB reads as buying power for deposit wallets.

Current Gaps

Gap	Current state
Bridge quote CLI	SDK-only via `pkg/bridge.GetQuote`
Bridge status CLI	SDK-only via `pkg/bridge.GetDepositStatus`
Quote acceptance	Not wrapped by polygolem; the deposit address flow is the supported CLI path
