USDC

USDC (USD Coin) is a regulated, USD‑backed stablecoin used widely across centralized and decentralized finance. Each USDC token is intended to represent one U.S. dollar of custodial reserves, and the token is issued under regulatory frameworks that vary by jurisdiction.

In context

On Polymarket you fund trading by moving USD value on‑chain as USDC on Polygon. Polymarket uses a wrapped form of USDC called pUSD for trading, so users bridge or transfer USDC on Polygon and interact with the Relayer and CTF contracts using pUSD balances. You’ll typically see balances, orders, and settlement denominated in pUSD on the platform; USDC is the underlying stable asset.

Because Polymarket runs on Polygon, use the Polygon (chain ID 137) USDC token when on‑chain transfers are required. Wallet connectors supported by Polymarket (for example MetaMask, Phantom, Rabby, Bitget, OKX, Coinbase) can hold and transfer USDC on Polygon; the Relayer sponsors gas so you don’t need MATIC to execute trades.
