Siren is a decentralized options trading protocol with a full-featured trading experience that allows traders to maintain custody of their crypto. Siren supports options trading on multiple currencies, including ETH calls and puts, MATIC, Sushi, Uni, and more.
Siren is currently in the process of developing a new version of the protocol. The new Siren will have a testnet launch in Q2 2023.
Options
Options are a financial primitive from which one can build many different more complex financial instruments. At their core, options give a trader the choice to buy or sell an asset at a predetermined price at a known time in the future. This is useful for protecting one's self (also known as hedging) against possible price changes in the asset, as well as speculating on these price changes.
Core Protocol Mechanics
Siren uses a fully-collateralized approach to writing options that doesn’t require any oracles to function. A single MarketsRegistry contract creates and coordinates individual markets. Once a Market contract is created anyone can interact with it in a permissionless manner. The solvency of a position is ensured at all times by the collateral locked in the smart contract.
