## <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Token - collateral

<mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Token (s) are **synthetic claims** on the future price movements of the supported cryptocurrencies, embedded as value *smart contracts* exe over the <mark style="color:blue;">Qtum</mark> Virtual Machine. <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Token uses QRC20 programming standard, smart contracts are settled algorithmically using **Synthetic Exchange** blockchain as a service (utility).

When user interacts with Synthetic Chain QRC20 smart contracts, we provide two instances of hashing the *contract data* over the blockchain. \
\
1`]`User contract variables are hashed as bytedata at `contract initiation`\
\
`2]`User input variables are evaluated for profit / loss at   `contract settlement`

The blockchain interworking with tokenized <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> series trading pairs, are dependent on the amount of deposit of <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Token used each trade, equivalent to USD nominal value, at block duration zero and selected execution price.

<mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Tokens are unequivocally **fungible** for all contract series provided on Synthetic Exchange. <mark style="color:green;">Cryp</mark><mark style="color:yellow;">to</mark><mark style="color:red;">ken</mark> is a derivatives contract following a synthetic representation of the underlying holdings, not trading of the underlying spot position.

Hashing of the smart contract is done via <mark style="color:blue;">Qtum</mark> **bytedata transmission** and is fast and 100 dependable without any downtimes. Transaction fees for CRT Token trading are executed in Qtum cryptocurrency, affordable equating to 10 cents and propagated over 32 second <mark style="color:blue;">Qtum</mark> blockchain. Synthetic Chain only requires single block confirmation, before the trade is visible on the [Qtum ledger](https://qtum.info).&#x20;

## <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Token - input variables

Depending on a set of smart contract variable, and their outcomes expressed over time, the Users are able to make trades and review pending trades by expressing the following criteria: <br>

📍 SUPPORTED CRYPTOCURRENCIES

Users **select** a Contract Series `crtBTC , crtETH , crtBNB,  crtNANO, crtLTC, crtQTUM, crtSOL, crtPAXG`\
\
📍 SUPPORTED DELTA

Users **select** both Types of Contracts `LONG` vs `SHORT`&#x20;

📍 SUPPORTED TRADE PRICE ORACLE

Users **select** the future `fPRICE` \
\
📍 SUPPORTED TRADE DURATION&#x20;

Users **select** a time before `tEXPIRATION`&#x20;

A difference between the `Spot Price` and `fPRICE` is the amount of <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Collateral required for each <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> traded, plus additional amount of <mark style="color:blue;">Qtum</mark> cryptocurrency used as cost to process the transaction on-chain, hashed and secured.

## <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Token - balance

Synthetic Chain is a TypeScript programming language application, build on Vue JS (+Nuxt) UX. The Electrum based <mark style="color:blue;">Qtum</mark> wallet, supporting <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> smart contract wallet addresses enabling users easy access and safe storage of their <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> token holdings.&#x20;

## <mark style="color:blue;">Qtum</mark> Coin - balance

Once users add <mark style="color:blue;">Qtum</mark> coin balance to Synthetic Exchange wallet, it enables the account holder to pay for <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> transactions. We encourage all users to transfer 1 <mark style="color:blue;">Qtum</mark> coin to our application to 1 qualify for our Token AirDrops, and to have sufficient funds to make <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> trades.

Example 1 - is an excerpt of our <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> application displaying bot <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> account address as well as <mark style="color:blue;">Qtum</mark> cryptocurrency account address. This account has around 1.2077514 <mark style="color:blue;">Qtum</mark> and 79,993.35 <mark style="color:green;">C</mark><mark style="color:yellow;">R</mark><mark style="color:red;">T</mark> Token.
