Some examples of highly rated ones that are also operational (NEX is still very much a work in progress at the moment) include IDEX, Stellar, and Waves. The advantages that NEX intends to offer over the current crop of decentralized exchanges are performance, usability, and the aforementioned capability to use fiat to enter the exchange. The final feature of the template is the implementation of NEP5 compliant methods that will be required for advanced token interaction needed by exchanges or other dApps.

  • Some examples of highly rated ones that are also operational (NEX is still very much a work in progress at the moment) include IDEX, Stellar, and Waves.
  • In these instances, the whole transaction will be rejected along with any funds sent.
  • The engine is also able to ‘batch’ matched orders back to the blockchain, improving scalability.
  • In the second method, the user can specify a preferred asset type, with NEX performing an automatic conversion.

Once the trades are matched with the other party, they are signed off-chain and committed back on-chain to the user accounts. For cross-chain exchanges, since the engine is off-chain, it will be able to communicate with smart contracts on any number of chains. NEX is billed as a ‘high performance trade and payment platform’ that is built on the NEO blockchain. Its key value proposition is that it allows both cross chain exchanges and fiat-crypto exchanges. Crucially, it intends to achieve this while also delivering the highest standard of trading performance.

Key to NEX’s performance promises is its unique off-chain matching engine. While NEX has yet to release technical specifics on its matching engine (its Github is still relatively empty), it has explained how this engine would work. The ICO smart contract has several methods, some of which have to be invoked by the owner and some which can be called by everyone.

Where Does Neon Exchange Fit In?

Holders of the NEX token will be allowed to share in the revenues generated by the fees charged on NEX. The minimum revenue share will be 25%, with the potential to be increased to 75% if a user decides to stake his or her NEX tokens for up to 2 years. Some solutions other decentralized exchanges implement to attempt to get around this include state channels and off-chain relay. Many think that NEO could eventually unseat Ethereum as the premier smart contracts platform, mainly due to scalability. Right now, Ethereum does only about 15 transactions per second whereas NEO has a theoretical limit (emphasis on theoretical) of 10,000 transactions per second. There are also questions concerning the amount of centralization involved in NEO’s smart contract compared to other blockchains, such as Ethereum and Bitcoin.

In this case, the ICO smart contract has the hash 70b3f7098a9a3f2361a1f0c312e9842ec4ca6dc6, which we will need to use for all the method invocations. You can confirm that the private network is running with “docker ps”. Alternatively you can also manually crypto greed and fear index compile the Python smart contract code, you can read more about this in the template README. If you want to disable the KYC process, simply remove the KYC check at crowdsale.py#149 (“if not self.get_kyc_status(attachments.sender_addr, storage)”).

This post dives into the neo-ico-template of the Neon Exchange (NEX), and how to use it as an ICO developer to configure, compile, deploy and test the ICO smart contract. After all, how would a user know whether the engine is matching trades fairly? For one, NEX ensures that the engine never has access to the full balance of a user’s account; how to get crypto price alerts only active orders. Second, the deterministic algorithm that it uses to match trade will be made public. Third, NEX will also offer bounties for spotting errors in the engine. The way that NEX will allow users to use fiat currencies to enter into the exchange is through a partnership network with various financial institutions.

Reduced performance means a lack of capability to execute more complex trades as well as giving up arbitrage opportunities. NEO, the smart contracts platform sometimes called the ‘Chinese Ethereum’ (as it is backed by the Chinese government), has been rising fast. At the time of this writing, it is the 11th most x11 coins valuable cryptocurrency with a market capitalization of about $5.5 billion. This guide uses neo-python, therefore set that up as first step. Clone the repository, setup a virtualenv and install the requirements. The whole process is covered as a detailed step-by-step guide in the neo-python README.

As for the fees themselves, NEX operates on the market maker/price taker model. Market makers will pay no fees while price takers pay a fee ranging from 0.13% to 0.25%, depending on trade volume. Another defining component of NEX is its web extension for improved usability.

Now let’s dive into the configuration of the smart contract, in particular the name, symbol, ownership, supply and amount of tokens a participant gets for sending NEO or GAS. With a maximum of $25 million for its ICO, NEX is far from a ‘mega ICO.’ It doesn’t even have a Discord or Telegram group. There is a NEX subreddit but it is apparently unaffiliated with the official NEX team, and there have been warnings that it is a scam; it has since been made private. Yet, there is a good chance that the full 25 million will be sold out within the first round of the ICO.

ICO Drops is an independent ICO (Token Sale) database and is not affiliated with any ICO project or company. Our Interest Level does not constitute financial or investment advice. We publish guides, reviews and news on tech, cryptocurrency, Bitcoin, blockchain & privacy. Our content is updated regularly to keep our privacy-minded readers safe, informed & up to date. Out of the 50 million NEX tokens, 25 million will be made available for sale. There will be no private sales, and while Chinese citizens can participate, US citizens, despite NEX’s best efforts, will not be able to.

We performed all the steps needed to run an ICO with the NEX ICO template. This step also compiles the Python code to NEO bytecode, producing a file with the name “ico_template.avm” (located in the template directory, next to the ico_template.py file). It seems that the NEX project is operating slightly behind its planned schedule. It’s already one month into the second quarter of 2018, yet a couple of milestones designated for the first quarter have yet to be achieved. NEX’s roadmap plans for the mainnet release and start of trading operations to begin in the third quarter, however, it looks like there’s a decent chance that it may fall behind schedule.

In the second method, the user can specify a preferred asset type, with NEX performing an automatic conversion. Unlike most blockchain projects nowadays, the NEX token will not be a utility token. Instead, the NEX token will function more as a stake in the entire NEX.

ICO Drops receives a fee for advertising certain token sales, in which case such listing will be designated accordingly. As it is with the entire concept of blockchain and decentralization in general, the problem with the decentralized model comes down to performance. One of the main advantages of centralization is efficiency and scalability; this is a key reason why blockchain is still far from mainstream use. An oft-mentioned statistic is Ethereum’s 15 transactions per second compared to Visa’s 40,000 to 50,000 transactions per second. This will allow projects to avoid the issues that occurred during the RPX token sale, which required Red Pulse to process many manual refunds.
