JOYSO is a hybrid-decentralized exchange (HEX)

Fast and fully-featured like a centralized exchange, and secure, like a decentralized exchange. Watch demo video

What problem does this solve?

Centralized Exchange

  • With a centralized exchange you need to trust them to protect your private key from hackers. Your privacy and your crypto are at risk if the exchange is hacked.

Decentralized Exchange

  • Fully decentralized exchanges are expensive in gas fees and don't do order matching as well as centralized databases. You risk not getting the best price. Users wait for confirmations and in some cases transactions fail.

The Solution: Hybrid-decentralized exchange (HEX)

The future is hybrid. Centralize for speed, decentralize for security. With JOYSO we decentralize access. You don't need to trust a central exchange with your private key or personal information. But we centralize order management, improving speed, matching and user experience compared to decentralized exchanges, and reducing costs.

Key components

How do we generate profit?

Income will be generated from trading fees in ETH or JOY effective from the beta launch; June 2018. These will be set around 0.1% for order makers and 0.2% for order takers.

Our price strategy is to attract users with a 50% discount for JOY token use. We will generate transactions and advertising by offering free and frictionless listings to ICOs.

Advertising on JOYSO through the JoySelect program will also be competitive, with a 50% discount for ICOs paying with JOY.

Hybrid Decentralized Token Exchange

The Future is Hybrid


1. What is Blockchain?
A blockchain is a distributed, cryptography-powered database that maintains a list of records, timestamped and chained together to prevent revision or tampering.
2. What is Ethereum?
Ethereum is an open-source, public, blockchain-based computing platform featuring smart contracts - contracts which are written in to the code and execute automatically when specified conditions are met.
3. What is an ERC20 Token?
ERC20 is an Ethereum token standard, which guides developers in programing how a token will function on the Ethereum blockchain. It is the most widely used token.
4. What is an ICO?
An ICO is an ‘Initial Coin Offering’. It is a way for startups to do crowdfunding using cryptocurrency as the investment medium. In an ICO, a percentage of the newly-issued tokens is sold to early backers of the project in exchange for specified privileges.
5. What is a centralized exchange?
It’s an exchange which holds and controls the customers’ funds on their behalf. Their strength is that they are fast and their centralized database supports sophisticated order matching, hence good prices. Their weakness is that they are vulnerable to hacking and governance problems. Hundreds of millions of dollars worth of contributor funds has been stolen or hacked.
6. What is a decentralized exchange?
A decentralized exchange is one without a third party service holding the customers’ funds. Instead, trades occur directly between users, cutting out the need for the customer to trust the exchange and their security practices. However, fully decentralized exchanges put orders and order-matching on the blockchain, risking sub-optimal prices and creating delays that frustrate users and create security/arbitrage risks. Poor liquidity is another issue.
7. What is a hybrid exchange (HEX)?
A hybrid exchange comprises a decentralized architecture for control of funds and a centralized database for dynamically matching market transactions. Only when a deal is done and tokens are confirmed available is the transaction published on the blockchain. Users do not relinquish control of their assets and have the benefit of a dynamic market where trades are processed sequentially, in near real-time.
8. How does JOYSO work?
JOYSO is a hybrid exchange, combining centralized and decentralized design for efficient off-chain order matching while ensuring privacy and security through smart contracts. The user deposits into the smart contract, then sends an order to JOYSO, where the order is matched. When a match is found, the smart contract verifies the user’s signature and publishes the transaction on the blockchain. For further detail, see the white paper.
9. In what regions will JOYSO operate?
JOYSO serves the global market except countries where cryptocurrency or ICOs are prohibited. It is a requirement that you check your local regulatory environment.
10. On what exchanges will JOY be traded?
JOY will be traded on any exchange supporting the ERC20 standard.
11. What is the point of the JOY Token?
Using the JOY token while trading will entitle users to a 50% transaction fee discount. The discount does not apply to gas fees. Also, JOY token holders will have the right to vote on various governance and operational issues, for example; which new tokens should be listed on the exchange.
12. How does JOYSO make profit?
JOYSO generates income from transactions fees, approximately 0.1% commission for the order maker and 0.2% for the order taker. Our price strategy is to attract users with a 50% discount for JOY token use. JOYSO also generates transactions and advertising by offering free and frictionless listings to ICOs.
13. How does JOYSO save users gas (transaction costs)?
The efficiencies of the HEX structure mean a low cost operation with an attractive feature set. Because JOYSO does not store the private keys of users, we do not required expensive hardware and software systems to segregate and protect them. We mitigate the higher gas fees associated with decentralized exchanges by zipping the input arguments and optimizing gas consumption.
14. What is the total number of JOY?
200 million JOY will be issued; 50% in the crowdsale, 25% via private placement and 25% as incentives for the JOYSO team.
15. Are JOY tokens securities?
No. JOY is deemed a utility token, as it provides discounted transaction fees in the JOYSO environment. It is not a type of security.
16. Can I buy tokens using fiat (USD or another national currency)?
Currently JOYSO does not support fiat currency. In order to participate in the JOYSO ICO you require Ethereum (ETH) which you can buy through any fiat exchange. If you need help on this, contact us through [email protected]
17. Can I send ETH to the ICO directly from an exchange?
We do not support transfers made directly from exchange platforms for security reasons. The secure way to participate in the ICO is to send from an Ethereum wallet address. These would include My EtherWallet, Metamask, Parity, Mist and Ledger.
18. Is JOY transferable?
JOY will be transferable upon purchase, and will be tradable after the ICO ends in late March, 2018.
19. What will happen with unsold tokens?
Unsold tokens will either be transferred back to the JOYSO exchange system, or be reserved for the next ICO. All generated but unsold tokens will be released over future years at a rate no higher than 15% per annum.
20. What risks are involved in the ICO?
In all cases including this one, the purchase of tokens in an ICO represents a high risk to any contributor.
There is a risk that in some jurisdictions that the JOY Token and related digital assets may be deemed by regulators to be a security, or that it may be judged to be a security in the future.
The token offering involves new software and leading edge technologies that may not meet the objectives laid out in the white paper.
There are security risks during the ICO. Attack vectors include the JOYSO website, your wallet software, the Ethereum network, Internet infrastructure, the JOY token source code and associated software, infrastructure or smart contract.
21. What’s the development roadmap?
Immediately after the ICO, we will migrate the Order Matching Engine, the trading engine and the smart contracts to the Ropsten Test Network so that we can prove all functions executable. Proof-of-concept has been done on the testnet for deposits, withdrawals, order matching and order cancellations. Server-side is operational but further testing will occur up to and after the ICO. Face-to-face user testing and independent auditing will be done in March/April and in May the application will be migrated to the mainnet. We will scale the service over the subsequent months and aim to reach $20M daily trading volume by December 2018. Using a trading API we aim to be capable of cross-centralized exchanges by December 2018. We will deliver margin trading by March 2019 and have an off-chain payment service by June. Mobile payment and mobile wallet are currently scheduled for September 2019.
