Options traders have come to rely on tools in traditional finance that were refined over decades.
And with options being fairly new to DeFi, SIREN aims to fill a niche by building a platform suited for sophisticated options traders.
2/ To make full use of SIRENโs design which allows traders to easily swap options in and out in order to build complex positions, options traders need the necessary information to properly assess those positions.
This is why SIREN's UI displays the greeks for each option.
3/ Option "Greeks," named after the Greek letters that denote them, measure risks associated with a position.
4/ The greeks are calculated from the price of the underlying asset, strike price of the option, estimate of volatility of the underlying asset, time to expiration, current interest rate and any dividends payable on the underlying asset before the option's expiration date.
5/ Full explanations are a bit long for Twitter so we'll give you the TLDR on greeks:
Delta - measures the ratio comparing the difference between the underlying asset price relative to the price of the option
Gamma - if delta is an options speed, gamma is acceleration
6/ Theta - measures the rate of decline in the value of an option due to the passage of time sometimes referred to as time decay. Theta is indirectly proportional to gamma.
Vega - measures how much the value of an option changes when the implied volatility of that option changes
7/ The more time there is until expiration, the higher the vega is for an option.

Theta or time decay refers to the reduction in value of an option as the time to the expiration date nears.
SIREN AMM v2 mitigates theta decay loss using a Black-Scholes model for pricing.
2/ Two factors determine the price of each trade: spot price and slippage.
The spot price is determined using a Black-Scholes model, taking into account parameters like underlying price, time to expiration, option strike and implied volatility, coupled with a Chainlink oracle.
3/ Similar to other AMMs, trades will be impacted by slippage based on the size of the trade and available assets in the pool.
In other words, the larger the trade relative to the size of the pool, the higher the slippage. This slippage benefits liquidity providers of the pool.
2/ This nautical-themed on-chain options marketplace launched its alpha release in December 2020 and is about to embark on the next chapter of its journey with SIREN Markets launching on mainnet today.
3/ SIREN protocol tokenizes both the long and short sides of an options contract as ERC20 tokens which enables options to be traded via its AMM.
In other words, SIREN doesn't require a third-party settling mechanism or order matching to complete option settlement on-chain.
2/ Gone are the days when yield farming AMM pools with leverage meant managing loans across several lending protocols in a risky position that was difficult to unwind.
Using Alpha Homora V2 makes this process a lot simpler and helps minimize the risks involved.
3/ With Alpha Homora V2, users can borrow multiple assets, re-leverage, and deleverage their positions easily in just a few clicks.
You donโt even need to have equal value of both tokens in order to yield farm. Alpha Homora V2 handles any borrowing and swapping for you.
โ๏ธ Its self-proclaimed army of โWhite Walkersโ is growing with new dedicated communities launched for its SnowSwap users in:

2/ SnowSwap continues to make strides towards major partnerships having had Quantstamp review its smart contracts.
Many in the SnowSwap community are also excited about the recent announcement that 1inch is integrating SnowSwap's liquidity pools.
