Opyn

Opyn is a European DeFi options trading protocol that lets users buy, sell, and create Ethereum-based options.

These are derivatives contracts that give the holder the right to buy or sell an asset at a predetermined price on the option’s expiration date.

DeFi users rely on Opyn’s smart contracts and interface to hedge against risk or to speculate on cryptocurrencies.

The platform offers free limit orders by using a specialized off-chain relay paired with on-chain settlement.
