1/ ๐Ÿ‡ DeFi Pulse Drop #19: @sirenprotocol ๐Ÿ‡

On SIREN Protocol, both the long and short sides of an options contract are represented as ERC20 tokens.

This allows traders to swap in and out of options positions on both sides and build complex portfolio positions via SIREN's AMM.
2/ It starts off with Liquidity Providers depositing collateral into the SIREN AMM pool. So for WBTC/USDC calls, the collateral would be WBTC.

When a trader goes to buy options from the AMM, the collateral held within the pool is used to mint a pair of tokens: bToken and wToken.
3/ bTokens or buyTokens are sent to the buyer and gives the holder the right to purchase or sell the underlying asset at a predetermined strike price.

Users pay a premium to the pool in the collateral asset each time they make a trade which incentivizes liquidity providers.
4/ Meanwhile the wTokens, short for writeTokens, stay in the pool. If the option is unexercised, wTokens allow you to withdraw the collateral or withdraw the exercise payment from the contract after expiration.

LPs passively become covered option writers to meet trade demand.
5/ SIREN AMM v2 can trade up to 6 SIREN options contracts which all share collateral and payment assets in a single pool.

This enables liquidity roll over when a market expires for a seamless UX for LPs and spreads exercise risk across multiple strike prices and expirations.
6/ This design also requires no third-party settling mechanism or order matching to complete option settlement on-chain.

SIREN only trades bTokens, but not wTokens. However, trading of wTokens may become available in the future.

No one can escape time, not even options.

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.

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 SIRENโ€™s 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.

If you're new to options, you may find this helpful for becoming familiar with greeks. investopedia.com/trading/gettinโ€ฆ

Liquidity providers play a critical role in SIREN protocol as passive underwriters enabling traders to swap in and out of options positions.

Their liquidity is used to mint bTokens and wTokens, both sides of an options contract.
2/ SIREN's AMM can trade up to 6 SIREN options contracts which all share collateral and payment assets in a single pool.

As contracts expire the AMM uses its held wTokens to claim the collateral and/or payment locked inside options markets back into the pool.
3/ This means that liquidity providers are never required to manually roll over their assets when contracts expire making them passive underwriters.

SIREN is designed with a few key incentives to ensure the protocol has sufficient liquidity to meet options traders' demand.

Options trading has become popular as it becomes more accessible. On-chain options will become an important building block as DeFi matures.

SIREN has built an options trading UX catering to sophisticated users. defipulse.com/blog/siren
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.

1/ ๐Ÿ‡ DeFi Pulse Drop #15: Alpha Homora V2 ๐Ÿ‡

Meet the new Alpha Homora V2 set to launch on Feb 1st.

Improving on @AlphaFinanceLab's popular yield farming product, V2 supports more AMM protocols and yield farming with up to 9x leverage on select pools. defipulse.com/blog/alpha-homโ€ฆ
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 donโ€™t even need to have equal value of both tokens in order to yield farm. Alpha Homora V2 handles any borrowing and swapping for you.

What does the future hold for SnowSwap?

โ›„๏ธ Its self-proclaimed army of โ€œWhite Walkersโ€ is growing with new dedicated communities launched for its SnowSwap users in:
๐Ÿ‡ง๐Ÿ‡ฉBangladesh,
๐Ÿ‡ป๐Ÿ‡ณVietnam, and
๐Ÿ‡ฎ๐Ÿ‡ณIndia.
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.
3/ SnowSwap pools will likely see increased trading volume from DEX aggregators and earn more trading fees for liquidity providers as a result.

Apparently, thereโ€™s more brewing behind the scenes. SnowSwap tells us that they have 5 major partners that they plan to reveal soon.
