The Bridge API supports deposits from multiple chains and tokens. All deposits are automatically converted to USDC.e on Polygon, which is used as collateral for trading on Polymarket.

Minimum Amounts

Each asset has a minCheckoutUsd value—the minimum deposit amount in USD equivalent. Deposits below this threshold may fail to process. Most L2 chains (Polygon, Arbitrum, Base, Optimism) have low minimums of 2,whileEthereumdepositsrequire2, while Ethereum deposits require 7 minimum. Bitcoin and Tron have $9 minimums due to higher bridging costs.
