ETH on Polygon exists as Wrapped ETH (wETH) — an ERC-20 representation of Ether on the Polygon network. Relay lets you acquire wETH on Polygon from any starting asset — no account, no KYC, settling in seconds.

What Is ETH on Polygon?

Polygon PoS uses MATIC/POL as its native gas token, but ETH is available as wETH (Wrapped ETH) — a tokenised version used in DeFi. wETH on Polygon is used in:

• QuickSwap — Polygon's native DEX with wETH trading pairs
• Uniswap on Polygon — wETH/USDC pools with deep liquidity
• Aave on Polygon — Use wETH as collateral for borrowing
• Cross-chain composability — Hold ETH value on a low-fee chain

If you want ETH exposure on Polygon at low cost, wETH is the standard.
