What is SI?
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.
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. 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. a WBTC/USDC put is actually a USDC/WBTC call).
Tokenizing both sides of the contract allows SIREN to create secondary markets for both the long and short exposure. Under such a design in order to become a writer one purchases a wToken from the SirenSwap AMM (see below). A writer can also unwind their short exposure by selling the wToken back to the AMM. This streamlines the write-side mechanics by reducing it to essentially purchasing the underlying collateral at discount — as opposed to a typical design where the writer mints long tokens and has to then sell them in order to realize the premium.
SirenSwap AMM
Bootstrapping liquidity is core to creating a thriving market. Options are notoriously difficult when it comes to that. Not only does liquidity get fractured by combination of strike prices and expirations, it also requires sophistication on the part of liquidity providers in order to ensure fair and sustainable pricing.
To ensure liquidity on day 1 the SIREN protocol utilizes a custom SirenSwap AMM that uses a novel combination of a constant-product bonding curve and options minting to trade both bTokens and wTokens. Notably, the AMM doesn’t require any asset in the pool other than bTokens/wTokens in order to trade them against the collateral asset (e.g. WBTC). This increases LP capital efficiency and provides other benefits that we’ll expand on in further posts.
The SIREN core team believes that in these early days of Ethereum and DeFi less is more, so they designed SirenSwap to be a model-less market maker. This means there is no complex on-chain pricing formula nor oracle feed required in order for it to function. This makes it easy for anyone to become an LP to potentially earn trading fees."
SI was first tradable on 6th Mar, 2021. It has a total supply of 100,000,000. As of right now SI has a market capitalization of USD $19,879,486.07. The current price of SI is $0.199 and is ranked 3139 on Coinmarketcap and has recently surged 49.31 percent at the time of writing.
SI has been listed on a number of crypto exchanges, unlike other main cryptocurrencies, it cannot be directly purchased with fiats money. However, You can still easily buy this coin by first buying Ethereum from any fiat-to-crypto exchanges and then transfer to the exchange that offers to trade this coin, in this guide article we will walk you through in detail the steps to buy SI.
Step 1: Register on Fiat-to-Crypto Exchange
You will have to first buy one of the major cryptocurrencies, in this case, Ethereum (ETH). In this article we will walk you through in details two of the most commonly-used fiat-to-crypto exchanges, Uphold.com and Coinbase. Both exchanges have their own fee policies and other features that we will go through in detail. It is recommended that you try both of them and figure out the one that suits you best.
Select Fiat-to-Crypto Exchange for details:
- UpHold
Being one of the most popular and convenient fiat-to-crypto exchanges, UpHold has the following advantages:
- Easy to buy and trade among multiple assets, more than 50 and still adding
- Currently more than 7M users worldwide
- You can apply for UpHold Debit card where you can spend the crypto assets on your account like a normal debit card! (US only but will be in the UK later)

- There are limited buy/sell orders for more advanced users
- You can easily set up recurring deposits for Dollar Cost Averaging (DCA) if you intend to hold cryptos long term
- USDT, which is one of the most popular USD-backed stablecoins (basically a crypto that is backed by real fiat money so they are less volatile and can be treated almost as the fiat money it's pegged with) is available, this is more convenient if the altcoin you intend to buy has only USDT trading pairs on the altcoin exchange so you don't have to go through another currency conversion while you buy the altcoin.
Type your email and click 'Next'. Make sure you provide your real name as UpHold will need it for account and identity verification. Choose a strong password so that your account isn't vulnerable to hackers.
You will receive a confirmation email. Open it and click on the link within. You will then be required to provide a valid mobile number to set up two-factor authentication (2FA), it is an extra layer to the security of your account and it is highly recommended that you keep this feature turned on.
Follow the next step to finish your identity verification. These steps are a bit daunting especially when you are waiting to buy an asset but just like any other financial institutions, UpHold is regulated in most countries such as the US, the UK and the EU. You can take this as a trade-off to using a trusted platform to make your first crypto purchase. Good news is that the whole so-called Know-Your-Customers (KYC) process is now fully automated and it shouldn't take more than 15 minutes to finish.
Step 2: Buy ETH with fiat money
Once you finished the KYC process. You will be asked to add a payment method. Here you can either choose to provide a credit/debit card or use a bank transfer. You may be charged higher fees depending on your credit card company and the volatile prices when using cards but you will also make an instant purchase. While a bank transfer will be cheaper but slower, depending on the country of your residence, some countries will offer instant cash deposit with low fees.
Now you are all set, on the 'Transact' screen under the 'From' field, select your fiat currency, and then on the 'To' field choose Ethereum, click preview to review your transaction and the click confirm if everything looks good... and congrats! You've just made your first crypto purchase.
Step 3: Transfer ETH to an Altcoin Exchange
But we are not done yet, since SI is an altcoin we need to transfer our to an exchange that SI can be traded. Below is a list of exchanges that offers to trade SI in various market pairs, head to their websites and register for an account.
Once finished you will then need to deposit ETH to the exchange from UpHold. After the deposit is confirmed you may then purchase SI from the exchange view.
Apart from the exchange(s) above, there are a few popular crypto exchanges where they have decent daily trading volumes and a huge user base. This will ensure you will be able to sell your coins at any time and the fees will usually be lower. It is suggested that you also register on these exchanges since once SI gets listed there it will attract a large amount of trading volumes from the users there, that means you will be having some great trading opportunities!
Gate.io
Gate.io is an American cryptocurrency exchange that launched 2017. As the exchange is American, US-investors can of course trade here and we recommend US traders to sign up on this exchange. The exchange is available both in English and Chinese (the latter being very helpful for Chinese investors). Gate.io’s main selling factor is their wide selection of trading pairs. You can find most of the new altcoins here. Gate.io also demonstrates an impressive trading volume. It is almost every day one of the top 20 exchanges with the highest trading volume. The trading volume amounts to approx. USD 100 million on a daily basis. The top 10 trading pairs on Gate.io in terms of trading volume usually have USDT (Tether) as one part of the pair. So, to summarize the foregoing, Gate.io’s vast number of trading pairs and its extraordinary liquidity are both very impressive aspects of this exchange.
BitMart
BitMart is a crypto exchange from the Cayman Islands. It became available to the public in March 2018. BitMart has a truly impressive liquidity. At the time of the last update of this review (20 March 2020, right in the middle of the crisis with COVID-19), BitMart’s 24 hour trading volume was USD 1.8 billion. This amount placed BitMart on place no. 24 on Coinmarketcap’s the list of exchanges with the highest 24 hour trading volumes. Needless to say, if you start trading here, you will not have to worry about the order book being thin. Many exchanges does not allow investors from USA as customers. As far as we can tell, BitMart is not one of those exchanges. Any US-investors interested in trading here should in any event form their own opinion on any issues arising from their citizenship or residency.

If you are planning to keep("hodl" as some may say, basically misspelt "hold" which get popularised over time) your SI for a considerable long time, you may want to explore ways of keeping it safe, although Binance is one of the safest cryptocurrency exchange there had been hacking incidents and funds were lost. Because of the very nature of the wallets in exchanges, they will be always online("Hot Wallets" as we call them), therefore exposing certain aspects of vulnerabilities. The safest way of storing your coins to date is always putting them into a type of "Cold Wallets", where the wallet will only have access to the blockchain(or simply "go online") when you send out funds, reducing the chances of hacking incidents. A paper wallet is a type of free cold wallet, it's basically an offline-generated pair of public and private address and you will have it written somewhere, and keep it safe. However, it is not durable and is susceptible to various hazards.
Hardware wallet here is definitely a better option of cold wallets. They are usually USB-enabled devices that store the key information of your wallet in a more durable way. They are built with military-level security and their firmware are constantly maintained by their manufacturers and thus extremely safe. Ledger Nano S and Ledger Nano X and are the most popular options in this category, these wallets cost around $50 to $100 depending on the features they are offering. If you are holding your assets these wallets are a good investment in our opinion.
