# Deposit Funds

> Fund your wallet from any of 10 supported chains.

PolyWin accepts deposits from ten major chains. Send to your unique address and PolyWin auto-bridges and swaps to USDC on Polygon (where Polymarket lives) — no manual bridging on your side.

**Polygon is recommended.** It's the only direct-deposit option — no bridge fees, fastest settlement. Everything else is bridged and swapped automatically to Polygon USDC.

## How to deposit

<Steps>
  <Step title="Open the Wallet hub">
    Tap **🏦 My Wallets** from the main menu.
  </Step>

  <Step title="Tap Deposit and pick a network">
    PolyWin shows your unique deposit address for that chain.
  </Step>

  <Step title="Send from your source wallet">
    Send any amount of a supported asset above the network minimum.
  </Step>

  <Step title="Get notified">
    You'll receive a notification the moment the deposit lands and is credited as USDC on Polygon.
  </Step>
</Steps>

<Note>
  PolyWin charges **\$0** on deposits and withdrawals. Bridge providers may charge a small fee for non-Polygon networks — that's why Polygon is recommended.
</Note>

<Warning>
  Always double-check the chain before sending. Cross-chain transfers cannot be reversed.
