What is IDEX?

IDEX is a cryptocurrency exchange that aims to offer the user experience of a centralised exchange without compromising on any of the security benefits offered by decentralised platforms. It offers a peer-to-peer trading environment and uses smart contracts to communicate transactions to the Ethereum blockchain, allowing for the order book and your account balance to be updated in real time.

At the same time, platform users always retain control of their funds. IDEX cannot access your funds until you sign permission cryptographically for it to do so, and private keys are encrypted and then destroyed to provide increased security.

IDEX is part of Aurora, a banking and finance platform made up of a collection of Ethereum-based applications and protocols. Aurora is managed by Aurora Labs S.A., a company located in the Republic of Panama.

Available countries

A global exchange platform, IDEX offers its services to users all around the world.

How much will it cost me to use IDEX?

There are no deposit or withdrawal fees on IDEX, but you will need to pay trading fees:

  • 0.2% for market takers
  • 0.1% for market makers

You should also be aware that market takers are responsible for covering the Ethereum gas fees for each trade.

Are there any transfer limits?

IDEX imposes a minimum order limit of 0.15 ETH for market makers, and 0.05 ETH (equivalent) for takers. In order to cover gas fees, a minimum withdrawal limit of 0.04 ETH applies for all tokens.

Is it safe to use IDEX?

As a decentralised exchange, IDEX offers some key security advantages over centralised platforms. It runs as a node on the Ethereum network, which means it offers all the security benefits that blockchains provide.

There’s no central point of failure which hackers can target, and IDEX doesn’t control user funds. Instead, any funds you deposit are held in smart contracts on the Ethereum blockchain, and are only transferred when you use your private key to sign a transaction.

When you unlock your wallet, your private key is encrypted in browser memory and can only be accessed inside the IDEX app. Private keys are never transmitted outside the device, and when you sign out the private key is destroyed from memory.

For further peace of mind, IDEX features Ledger Nano S hardware and MetaMask web wallet integration.
