About Siren

What Siren is, how it works, and how to read its market figures.

What is Siren (SI)?

SIREN is a distributed protocol for creating, trading, and redeeming fully-collateralized options contracts for any ERC-20 token on Ethereum. About SIREN 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.

How does Siren work?

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. With SIREN, both the long and short side of the contract are tokenized.

What is Siren used for?

The buyer’s side (bToken) gives the holder the right to purchase or sell the underlying asset at a predetermined strike priceThe seller’s/writer’s side (wToken) allows the holder to withdraw the collateral (if the option was not exercised) or withdraw the exercise payment (if the option was exercised) from the contract after expiration. When a trader buys a put the on-chain token amount is multiplied by the strike. For example, a 1 WBTC $20K PUT will result in 20,000 bTokens. For the same reason, a put is just a reversed-assets call (e.g.

Where can you buy Siren?

Siren (SI) is traded on a wide range of centralized and decentralized exchanges. The most liquid markets for SI sit on tier-1 venues - the sort of exchanges where institutional desks and professional market makers rebalance continuously - which is what keeps the spread tight and the last price tied closely to fair value.

The price and 24-hour volume on this page combine the exchanges ReadPrices tracks for SI. Before you trade, compare the fee schedule and the order-book depth on the venue you plan to use: the same coin can cost noticeably more to buy on a thin market.

What is the daily trading volume of Siren (SI)?

The reported 24-hour trading volume of Siren is $4.71. Volume is a live reading of how much SI changed hands across all tracked exchanges in the past day and tends to rise during periods of price discovery and fall during consolidation.

For traders, the ratio between volume and market cap is often more informative than either number on its own: a high vol-to-mcap ratio indicates liquid, actively traded supply, while a low ratio suggests that most holders are sitting on the asset.

What is the highest and lowest price for Siren (SI)?

Siren reached an all-time high of $4.37 on March 6, 2021, and an all-time low of $0.002824 on July 6, 2026. It is currently trading -99.92% from its peak and +22.19% from its bottom.

The distance from ATH is a useful gauge of recovery potential during a bear market and of stretched positioning during a bull market. Combined with the all-time-low figure it provides a quick statistical frame for thinking about where SI sits in its long-run price range.

What is the market cap of Siren (SI)?

Siren's market capitalization is currently $230.69K, and it is ranked #9999 by market cap on ReadPrices. Market cap is calculated as the current price multiplied by the circulating supply (66.86 million SI are actively circulating today).

Market cap is a common but imperfect measure. It reflects the theoretical value of every circulating token at the current market price, but it doesn't capture how thin the top of the order book might be - an important caveat for tokens with low floats or illiquid cap tables.

What is the fully diluted valuation of Siren (SI)?

The fully diluted valuation (FDV) of Siren is $345.04K. FDV is a projection of what the market cap would be if every token that will ever exist - including those that have not yet been unlocked, mined or issued - were in circulation at the current price.

FDV is a useful second reading alongside market cap. A large gap between mcap and FDV signals that future token emissions could dilute current holders, while a small gap indicates that supply is already mostly out.

How does the price performance of Siren compare against its peers?

Over the past 24 hours, Siren has moved -. Over the past seven days, the change is -7.34%. Comparing these figures to the change in the whole crypto market cap (shown in the line at the top of this page) tells you whether SI is leading, lagging or tracking the broader market.

For deeper analysis, the Categories page groups coins by theme - Layer 1, Meme, DePIN, AI, RWA and so on - and lets you compare Siren against its closest peers. Each category page lists its coins with their seven-day price lines in a single view.

How to store Siren?

Like any crypto asset, the right way to store SI depends on how often you plan to use it. Long-term holders typically self-custody using a hardware wallet such as Ledger or Trezor, which keeps private keys offline and immune to most remote attacks.

For active traders, a reputable custodial exchange wallet can be appropriate, especially one with clear proof-of-reserves attestations. Whatever approach you choose, the most important rule is to keep your recovery phrase offline, never share it, and never enter it into a web form or attached to a DM - no legitimate support agent will ever ask for it.
