IDEX Cryto Exchange Review



What is IDEX Crypto Exchange?

IDEX is an Ethereum based Dapp designed to operate as a token exchange. It provides the users to perform real-time trading of Ethereum and ERC20 tokens. Their focus on ETH, means you will not find a single BTC exchange pairs on the platform.

IDEX Crypto Exchange Workflow

The workflow of IDEX completes in three steps.

  • Smart Contract
    The Smart contract stores the assets and Execute the trade settlement. All these trades need to be authorized by the user’s private keys. The design of the IDEX smart contract authorizes only exchanges to submit the signed trades to Ethereum and this helps IDEX to keep a track of processed transactions and separate trades from the final settlement.
  • Trading Engine
    IDEX update the trade details in real time. These trades have the authority to use private keys. The authorization process stops the initiation of unauthorized trades and disallows users to quash any completed trades.
  • Transaction Processing Arbiter
    The Arbiter manages the pending transaction queue and dispatches them in sequence. It also manages the synchronization of a smart contract with the exchange balances. As a decentralized exchange, IDEX provides security and auditability along with the speed and user experience of centralized exchanges.

Real-time Exchange

IDEX provides an experience of a centralized exchange along with the security of the blockchain. It is the only decentralized exchange with high-throughput trading in real time.

IDEX supports:

  • Continuous trading across multiple markets.
  • Placing true market orders.
  • Fulfilment of multiple orders at once.
  • Immediate cancellation of orders without any gas costs.

How IDEX Exchange Works?

This IDEX exchange review details how IDEX works. Do not forget to read about IDEX Ecosystem to understand IDEX working. On IDEX platform, the smart contract manages all the funds. The funds cannot be altered unless one is having the private key.

To begin, users need to deposit funds into the exchange’s smart contract.
Users can create or integrate a new wallet by using the dropbox of the account placed in the top right corner of the exchange.

The exchanges provide a private key and a Wallet Keystore File.

How to open a wallet?

Users can open up a wallet or can access an existing wallet in four ways.

  • Keystore File:
    They can directly upload their private keys to ethereum address by using a keystore file.
  • Manually Entered Private Key:
    Users can manually enter their private key to unlock an Ethereum address. By the way, Manual entering of private keys acts as an invitation to phishers, which is the most vulnerable option for accessing funds. The EtherDelta DNS hack is a live example of this.
  • MetaMask:
    They can unlock their MetaMask wallet and can access it through the exchange. The MetaMask provides protection against phishing, but not against malware.
  • Ledger Nano S:
    Users can directly deposit their funds by integrating the Ledger Nano S into the exchange. The use of ledger for trading insulates the risk of malware and phishing.

As a rule, Traders need to deposit the funds into the exchange’s smart contract. The Quick Balances tab at the top of the page enables you to deposit the funds from the wallet into the exchange.

To summarise, Users can start trading, once the fund gets deposited on the exchange. Moreover, Users can create a market or limits without paying any gas fees.

Ethereum IDEX Ecosystem

  1. The maker and taker deposit their tokens into the IDEX contract.
  2. The updated IDEX database includes the customer addresses and token balances.
  3. Maker creates and submits a signed order that includes the relevant trade data.
  4. IDEX confirms that the maker’s account has sufficient funds and that the signed transaction matches what they submitted to IDEX.
  5. If all checks in part 4 pass, IDEX add the order to the order-book.
  6. The taker submits a matching order, signing a transaction with the same price as the target order and an amount less than or equal to it.
  7. IDEX confirms that the maker’s account has sufficient funds and that the signed transaction matches what was submitted to IDEX.
  8. If all checks in part 7 pass, the trade is marked as matched and the order book is updated.
  9. The IDEX database is updated to reflect the new balances, and both traders can continue to make new trades based these updates. Simultaneously, Traders add the signed order to the queue to  broadcast to the Ethereum network for processing.
  10. After all dependent trades have mined, the transaction is dispatched to the blockchain.
  11. The transaction is mined and the contract balances update to reflect the trade.
  12. Once the transaction has mined the maker and taker are able to withdraw their funds.

As the exchange itself executes the trade, users can cancel trades on IDEX with no extra payment. The smart contract of exchange is responsible to broadcast trades on the network. So, until the transaction is broadcasted users can cancel the trade.


IDEX Account Security

IDEX Exchange review will be incomplete without mentioning the Security part. The decentralized exchange offers many security features not supported by centralized exchanges. This platform offers all the security because the exchange itself runs as a node on the Ethereum network.

The smart contract of IDEX exchange keeps the funds locked-in until it gets any sign of transaction by the private key. Additionally, Integrating the Ledger Nano S with the platform makes it the most secure trading exchange.

Account Verification

IDEX divides user verification into tiers.

  • Tier 1 –
    It is the minimum requirement for IDEX account. Hence, users of Tier 1 are limited to $5000 USD worth of withdrawals per day
  • Tier 2 –

The crypto exchange recently enforced this verification. Users required to verify the accounts at least to Tier 1 within Aug 26, 2019. Not verifying the account led users to lose previous trade access.
