Résumé court : If you search for “siren crypto” right now, you’ll probably find two totally different projects sharing a variant of the same name. Siren Protocol (SI) is a 2021 Ethereum-based DeFi options protocol that trades at 0,003884 $ with a capitalisation de 87 000 $. The other — $SIREN on BNB Chain — is an AI meme coin that reached $3.83 before falling 93% to $0.26 in one week. This article discusses Siren Protocol of origin and explains why this name confusion is important.
The increase in “siren crypto” searches this week has nothing to do with Siren Protocol (SI). This peak of interest is linked to token $SIREN sur BNB ChainÂ: a meme coin linked to AI having experienced a spectacular increase of 6800% then a fall of 93% in less than a week, sparking debates on social networks and numerous information seekers.
In this confusing context, many end up on Siren Protocol (SI) — a totally separate project — and confuse them. This name overlap creates a real risk: some investors wishing to learn about the same viral coin could buy the wrong token, and vice versa.
This article clarifies the situation on Siren Protocol (SI) — the DeFi options protocol on Ethereum.
What is the Siren Protocol (SI)?
Siren Protocol is a Centralized options trading platformlaunched on Ethereum in 2021. It allows the creation, exchange and settlement offully collateralized options on any ERC-20 token Рwithout an oracle, without an intermediary, and with each side of the contract tokenis̩ on-chain.
How Siren options work
Traditional options offer the right (without obligation) to buy or sell an asset at a defined price on a future date. Siren transposes this mechanism onto the blockchain:
- And writer creates an option contract by depositing the entire security (no partial collateral)
- The contract generates two tokens: one bToken (buyer side) and a wToken (seller side)
- These tokens are tradable on secondary markets – so you can buy or sell either side of the contract before expiration
- At settlement, contracts are executed on-chain according to the final price of the asset
The fully collateralized design eliminates counterparty risk: collateral is locked into the smart contract, ensuring that the writer can still honor the contract if the option is exercised. This represents a structural advantage compared to centralized options platforms, where solvency depends on trust.

Main observations
Market cap de 87 000 $Â: it’s a micro-cap, the total circulating value of the project is less than the price of a mid-range car. For comparison, theother SIREN (BNB) reached 2.8 billion FDV before falling.
TVL of 284Â 000Â $Â: although modest, the existence of a Total Value Locked (TVL) (capital actually deposited in smart contracts) distinguishes Siren Protocol from the same pure coins. This means that the protocol is actually used.
22.4 M out of 100 M offered in circulationÂ: only 22.4% of the maximum offer. Future releases could result in dilution if activity increases.
Comparison of SI vs. $SIREN (BNB Chain): The real differences
| Characteristic | Siren Protocol (SI) | $SIREN (BNB Chain) |
|---|---|---|
| Blockchain | Ethereum | BNB Chain |
| Launch | 2021 | Fin 2025 |
| Type | DeFi Options Protocol | Meme coin IA |
| Functional product | Yes (on-chain options) | Announced (DEX IA not launched) |
| TVL | 284Â 664Â $ | None |
| Market Cap | 87Â 190Â $ | 193Â 367Â 488Â $ |
| Prix | 0,003884Â $ | 0,2632Â $ |
| Distribution | Répartie | 88.5% held by whales |
| Variation 7j | −7 % (stable) | −83.9Â% (shot) |
| GitHub | Active | No audience |
The observation is striking: the Siren Protocol original — real product, TVL, open source code — has a market cap of $87K. THE same BNB coin with similar name — sans produit, 88,5 % contrôlé par des baleines, chute de 93 % — a atteint 2,8 milliards $ et reste valoriseé 193 M $ après crash.
This is a reflection of the crypto market: virality and narrative sometimes weigh much more than fundamentals – until that changes.
The SIÂ token: Governance and utility
The IS has two main functions in the Siren ecosystem:
1. Governance
SI holders can vote on on-chain governance proposals that determine the future parameters of the protocol: supported assets, fee structure, development priorities. Standard functionality in DeFi, similar to UNI or AAVE. To find out more, see: veToken, future of central governance.
2. Cost distribution
Fees collected via Siren options are redistributed in SI to active contributors. This generates a theoretical demand: the more activity there is, the more costs are generated, the more IS are distributed as rewards.
In practice: with $284,000 in TVL and a minimal daily volume (less than $20 on the most active Uniswap pair), the generation of fees remains negligible currently.
Why is Siren Protocol relevant (even with a micro-cap)?
The gap on DeFi options
On-chain options trading remains an underdeveloped sector of DeFi. While spot DEXs (Uniswap, Jupiter) achieve significant daily volumes and perpetual DEXs (Hyperliquid, dYdX) capture more than 10% of the CEX derivatives volume, options on-chain represent less than 1% of the global options market.
This sector represents a market of over $1 trillion in traditional finance, with very little DeFi penetration. Siren Protocol – one of the first fully collateralized on-chain options protocols – is positioned in a niche with potential, even if adoption remains limited.
Optimistic scenario for SI (theoretical)
If adoption of DeFi options accelerates (institutional demand, regulatory clarity, L2 integration…), pioneering protocols like Siren could benefit from a re-evaluation. A token with a market cap of $87K theoretically has strong potential if the protocol captures a significant share of the market – but this remains highly speculative and depends on adoption still lacking after five years of existence.
Bearish scenario for SI (realistic)
Siren Protocol has been around since 2021 without significant adoption. Less than $300,000 TVL and almost no daily volume after five years are signs of market fit difficulties. Other options protocols, with more capital, better UX and deployed on L2, are competing. The SI at $0.003884 likely reflects its actual utility – close to zero.

Name Collision Issue: Caution for Traders
The popularity of the term “crypto siren” illustrates the real risk of name collisions :
- Trader sees $SIREN BNB buzz on social media
- He searches for “siren crypto” on Google or an aggregator
- He finds Siren Protocol (SI) — un token différent à 0,003 $
- He buys IF thinking of buying the same coin
- He realizes too late that he acquired a $87K DeFi protocol instead of the same coin at $193K
Worse: he thinks he is buying $SIREN “on sale” without understanding that these are two assets on two different blockchains.
Always check the contract address and blockchain ahead of a token. Siren Protocol (SI)Â : Ethereum, 0xD23Ac271...5093de. The $SIREN BNBÂ: different contract and blockchain.
For traders wishing to avoid any risk of name collisions, there are established and very liquid tokens on Phemex: BTC, ETH, SOL, XRPas well as 300+ verified pairs, spot trading, perpetual contracts (up to 100x leverage), grid bots, automated DCA, and Earn products. All tokens listed are verified and contract addresses confirmed – minimizing the risk of confusion.
FAQ
Q: Is Siren Protocol (SI) the same as $SIREN on BNB Chain? No. Siren Protocol (SI) is a DeFi options protocol on Ethereum, launched in 2021 at $0.003884 and valued at $87K. $SIREN on BNB Chain is an AI meme coin, launched in 2025, having reached $3.83 then falling 93%. These are two separate projects.
Q : Que fait Siren Protocol ? Siren enables trading of fully collateralized on-chain options on ERC-20 tokens via Ethereum. Users create, buy and sell tokenized options contracts (bTokens for buyers, wTokens for writers). The protocol shows $284K in TVL but very little daily activity.
Q: Why is “siren crypto” trending? This term is creating a buzz because of the spectacular performance of $SIREN on BNB Chain: increase of 6,800%, fall of 93% in less than a week, concentration of 88.5% of the supply, and announcement of a major platform having generated $700 million in daily volume. This search volume spills over into Siren Protocol (SI), creating confusion.
