Industry Best Practices
Ethfinex’s security is based on the significant expertise gained by Bitfinex’s over it’s 4 year experience operating as one of the oldest cryptocurrency exchanges. As well as organizational and systems security best practices, there are 2 central themes for Ethfinex’s cryptocurrency specific security:
Cryptocurrency Offline Storage
The overwhelming majority of system funds are stored in offline, ‘cold’ wallets. Only approximately 0.5% of crypto assets are accessible in ‘hot’ wallets for day-to-day platform operations. As an added protection, the cold wallets are not available from the platform or the platform servers. The funds in offline cold storage require manual intervention by several members of our management to access.
User Account Protection
Some of the security measures highlighted below are in place by default, and others can be activated based on the security level you need. Please visit to check the security status of your account and see recommendations.
  • Two-factor authentication (2FA)
  • Advanced verification tools to monitor suspicious behaviour and the integrity of your account
  • Withdrawal Protection
  • Advanced API key permissions
  • Email Encryption with OpenPGP

Go Trustless
In the spirit of achieving ultimate security and transparency for users, and minimising every possible attack surface, the ultimate aim of Ethfinex is to be decentralised, settling transactions using blockchain based technology.
Currently a first step towards this is goal is available via the Ethfinex Portal, allowing you to choose to take your security into your own hands, instead of trusting our security systems with your funds.
The Ethfinex Portal allows you to view the Ethfinex order book and trade without needing to first deposit your funds to your Ethfinex account. The portal operates using decentralised exchange protocols, allowing the trades to be completed by smart contracts on the Ethereum blockchain. The current implementation uses only the 0x protocol, but in the future this will be technology agnostic and opened up to allow any other decentralised exchange protocol to connect with Ethfinex.
Because of the cost associated with every order being settled over the Ethereum blockchain this solution initially has a minimum order size of $200 equivalent. This is to prevent the current limited capacity of the blockchain becoming over-saturated with orders. For smaller orders it is still required for now to trust your funds to Ethfinex’s industry-best security practices.
