IDEX Review

A trading cryptocurrency guide must provide reviews of all of the top crypto exchanges out there, so that you can find the best cryptocurrency exchange site for you. This review of IDEX consists of four parts: general information, fees, deposit methods and security.

General Information

IDEX is a “decentralized exchange” that launched in October 2016.

IDEX is the first Ethereum based decentralized smart contract exchange to support real-time trading. It claims to be the most advanced Ethereum DEX. It supports limit and market orders, gas-free cancels, and the ability to fill many trades at once.

The exchange consists of a smart contract, a trading engine, and a “transaction processing arbiter”. The smart contract is responsible for storing all assets and executing trade settlement. The user has to verify all trades using the user’s private keys.

Unlike most other decentralized exchanges, IDEX has built a smart contract that only allows the exchange to submit signed trades to Ethereum. This enables the exchange to control the order in which transactions are processed, separating the act of trading from final settlement. As users trade, their exchange balances updates in real-time, while simultaneously they use their private keys used to authorize the trade in the contract. This authorization prevents users from rescinding any completed trades, and prevents the exchange from initiating any unauthorized trades.

On the date of last updating this review (17 July 2019), this trading platform had a 24 hour trading volume of  USD 1.705 million. This is not a particularly impressive trading volume. So if you’re looking for deep liquidity, this is not the place for you.

The platform is available in English, Spanish, Russian, South Korean, Vietnamese and Mandarin.

US-investors

The exchange does not list US-investors as prohibited from trading, but US-investors should do their own independent assessment of any problems arising from their residency or citizenship.

IDEX Trading View

Different exchanges have different trading views. And there is no “this overview is the best”-view. You should yourself determine which trading view that suits you the best. What the views normally have in common is that they all show the order book or at least part of the order book, a price chart of the chosen cryptocurrency and order history. They normally also have buy and sell-boxes. Before you choose an exchange, try to have a look at the trading view so that you can ascertain that it feels right to you. The below is a picture of the trading view at IDEX:

IDEX Fees

IDEX Trading fees

Every trade occurs between two parties: the maker, whose order exists on the order book prior to the trade, and the taker, who places the order that matches (or “takes”) the maker’s order.

IDEX’s trading fees for takers are 0.20%. This fee is slightly below the global industry average. The global industry average is arguably around 0.25%. IDEX also offers a discount for makers who trade at 0.10%. This is beneficial for the investors who are not interested in picking up existing orders from the order book but rather prefers to “go fishing” with maker-orders.

IDEX Withdrawal fees

We have not been able to find the withdrawal fees (at least not black on white). IDEX writes on its webpage that “when withdrawing tokens the fee amount is calculated using the Token/ETH exchange rate from the last 10 trades.” We have still not been able to exactly determine how to arrive at a withdrawal fee based on that information. Accordingly, we urge you to make your own analysis of the withdrawal fees at IDEX.

Deposit Methods

IDEX does not accept any other deposit method than cryptocurrencies, so new crypto investors can’t actually trade at this exchange. If you don’t have any crypto but want to start trading here, you will first have to purchase cryptocurrencies from another exchange. Then, as a second step, you can deposit them here. You can do this easy though.

IDEX Security

The servers of decentralized exchanges normally spread out across the globe. This is different from centralized exchanges that normally have their servers more concentrated. This spread-out of servers leads to a lower risk of server downtime and also means that decentralized exchanges are virtually immune to attacks. This is because if you take out one of the servers, it makes little to no difference for the network of servers in its entirety. However, if you manage to get into a server at a centralized exchange, you can do a lot more harm.

Also, if you make a trade at a decentralized exchange, the exchange itself never touches your assets. Accordingly, even if a hacker would somehow be able to hack the exchange (in spite of the above), the hacker can not access your assets. If you make a trade at a centralized exchange, however, you normally hold assets at that exchange until you withdraw them to your private wallet. A hacker can therefore hack a centralized exchange and steal your funds held at such exchange.

As this exchange is a decentralized exchange, we feel that it is appropriate to award it a security score of A+ (regardless of its score in the Mozilla Observatory-test).

***

Finally, as mentioned above, this is a decentralized exchange. Decentralized exchanges are still a minority on the cryptocurrency exchange market. The centralized exchanges still dominates the field (mostly due to better liquidity). In any event, if you’re looking for a decentralized exchange, you could also check out the following quite popular ones:

  1. DDEX
  2. Ethermium
  3. Counterparty DEX
  4. Bibox
  5. EtherDelta
  6. AirSwap.io
  7. Fcoin Exchange
  8. Switcheo Network
