Siren is the 'big boss' token in the decentralized options protocol, specifically innovating in on-chain derivatives trading. In this project, users have an 'unlimited pass,' allowing them to create and trade various asset options contracts on their own without needing anyone's approval. Whether it's cryptocurrencies, stocks, or the currently popular NFTs, all can become trading targets, making the gameplay incredibly rich!

Its core mechanism relies on automated market makers (AMM) to provide liquidity to the market. Users here have flexibility; they can act as option buyers, insuring their assets and hedging risks, or they can transform into sellers, earning premium income while they relax. This trading is quite advantageous.

The utility of this token is significant, mainly focusing on governance voting, fee discounts, and liquidity incentives. Holding it is like having 'decision-making power,' allowing participation in protocol parameter adjustments and contributing ideas for project development.

Now with the V2 version launched, there's even a 'partial collateral' model, which is like a 'timely rain' for option sellers, significantly lowering the capital threshold.

Siren's biggest highlight is the perfect combination of traditional financial derivatives and DeFi, bringing the market non-custodial hedging tools. However, the derivatives sector is highly competitive, and whether the protocol's liquidity and risk management can withstand this is the key challenge!
