How to fund Polymarket (buy USDC and deposit)
To fund Polymarket you need USDC on the Polygon network in a self-custody wallet. The fastest path: buy USDC at a crypto on-ramp (card or bank), send it to your wallet on Polygon, then deposit on Polymarket. Polymarket is non-custodial and restricted in the US — check your local rules first. Here's the full step-by-step.

Step 1 — Get a wallet
Polymarket runs on the Polygon network and uses a self-custody wallet (you control the keys). MetaMask or Coinbase Wallet both work. Install it, write down your recovery phrase, and add the Polygon network.
Step 2 — Buy USDC
USDC is a US-dollar stablecoin — $1 of USDC ≈ $1, so you're not exposed to crypto volatility between funding and trading. Buy it at an on-ramp with a card or bank transfer (options below). Buy USDC on Polygon directly if the on-ramp offers it — that saves a bridging step.
Step 3 — Send USDC to your wallet (on Polygon)
Withdraw the USDC from the on-ramp to your wallet address, choosing the Polygon network. Double-check the network — sending on the wrong chain can lose funds. Fees on Polygon are a few cents.
Step 4 — Deposit on Polymarket
Connect your wallet on Polymarket and deposit. Your USDC is now ready to trade event contracts. Start small until you're comfortable with how resolution works.
