WETH is a large-cap asset that represents the protocol's native governance or utility token. This asset is exposed to the underlying risks of Polygon PoS bridge, a protocol rated as Watch out.
WETH has an uncapped supply but has inflation control or burn mechanisms in place. ETH on Polygon is backed 1:1 by ETH locked in the Polygon PoS bridge protocol on Ethereum. ETH is "wrapped" to make it compatible with DeFi smart contracts. 1 Wrapped ETH is always equal to 1 ETH.
