OKX uses secure online and offline storage systems with multisig protection and multiple backups.

Secure online storage design

Offline asset storage — cold wallets — are the safest vaults for cryptocurrency. But crypto exchanges require ready access to some funds to deposit and withdraw funds for users. It’s possible thanks to online storage known as hot wallets.

Since hot wallet systems are connected to the internet, operating them safely is a bigger challenge. OKX has created its own semi-offline multi-signature mechanism. It supports quick, secure, and convenient deposits and withdrawals.

OKX's hot wallets use multiple technical solutions for greater convenience and security. OKX has semi-offline multi-signature mechanisms, online and semi-offline risk management systems based on big data. Multiple risk management methods verify deposits and withdrawals before sending them to the blockchain.

It’s impossible to compromise OKX's semi-offline servers even via a physical attack. Private keys are stored in RAM instead of permanent memory.

OKX doesn’t use the typical TCP/IP protocol for network communication. Instead, the exchange uses a semi-offline signature service that makes online attacks virtually impossible.

The multi-signature system requires several confirmations from authorized employees who are geographically separate and have backups in place.

OKX is prepared for various emergency scenarios with multiple backups and extensive redundancy plans.

Core features of the security protocol

  • The private key management system integrates decentralized storage
  • Each private key has a backup.
  • OKX has many emergency scenarios that allow them to enable backups.
  • It keeps private keys in its semi-offline signature devices’ RAM, preventing both online and offline attacks.
  • It has multiple risk detection and management mechanisms to prevent suspicious assets flows.

Benefits of the security protocol

  • OKX's security systems are designed to keep private keys safe against both online and offline attacks.
  • OKX's extensive backup and contingency plans aim to minimize withdrawal downtime due to emergencies and unforeseeable circumstances.
  • OKX's risk management systems flag and prevent suspicious deposits and withdrawals.

Secure offline storage design

Cryptocurrencies are innovative digital assets. They’re a great way to participate in trustless financial ecosystems. However, asset security that’s based on cryptographic functions and data protection is one of the major challenges for the industry.

Cryptography leverages extensively tested and widely accepted encryption standards (SHA-256 hash and ECDSA encryption). But data security, including private keys and passwords, remains the weakest link. Offline asset storage, also known as cold wallet systems, (not connected to the internet at all) are designed to counter these concerns.

How does OKX's cold wallet system work?

The security program encompasses all aspects: platform, assets, data, and access security. OKX is transparent and public with its protocols that guarantee the complete protection of funds on OKX. Multiple backups, bank vaults, and storage limits are only some of the measures taken.

Anything connected to the internet is inherently vulnerable. That’s why OKX keeps 95% of all funds on its offline, cold wallet system.

Even offline USB drives aren’t entirely safe from viruses and malware. That’s the reason why OKX's cold wallet system doesn’t interact with USBs and external memory devices.

A single point of failure is a critical threat. Access to OKX's cold wallet system requires confirmation from at least two authorized personnel.

Unexpected and unforeseeable events may happen. OKX's architecture offers protection by incorporating contingency plans, including the use of multiple backups.

Security threats to authorized employees can alter any system. As a countermeasure, OKX stores sensitive data in secure bank vaults requiring in-person access.

Core features of the security protocol

  • Each cold wallet address can store no more than 1,000 BTC.
  • OKX private keys never interact with the internet or USBs.
  • OKX private key backups are stored in secure bank vaults.
  • Access to decryption passwords and key backups is divided among four authorized employees.
  • Any cold wallet is no longer used for deposits after the first withdrawal occurs.
  • Employees who have access to passwords and backups live in different locations.
  • Private keys are moved online only once and never used again after.

Benefits of the security protocol

  • All assets in cold storage are spread across multiple addresses, with no single point of failure.
  • Access to cold wallets requires at least two authorized employees, preventing hacks and malware attacks.
  • Backups are stored in geographically different locations, providing additional security for potential unforeseeable scenarios.
  • Key retrieval from bank vaults requires in-person access, bypassing scenarios where authorized employees may be compromised.
  • Only one withdrawal per cold wallet address is possible, which reduces unauthorized access risks.


OKX's trading fees are different for regular and VIP users. Regular users are divided into tiers by total OKB holding. VIP users are divided by 30-day trading volume. Tiers update daily.

You always get trading fees of the highest tier among all markets. Let’s say, your 30-day trading volume for spot is 10,000,000 USD (tier VIP 2), volume for futures is 200,000,000 USD (VIP 3), and volume for options is 5,000,000 USD (VIP 1). Hence, your tier would be VIP 3 for spot, futures, options, and perpetual swaps. It means that you’d get trading fees of this tier for all markets.

OKXChain is a set of open-source public chain projects developed by OKX, which achieved both high performance and decentralization. It aims to promote the development of trading services based on blockchain technology.

As an open-source public chain ecosystem, OKXChain allows users to launch a variety of decentralized applications, issue their digital assets, create their own digital asset trading pairs, and trade freely. Any user can campaign for a network validator, participating in community development. Meanwhile, it introduced Ethereum Virtual Machine and OKX cross-chain gateway, and will also be compatible with IBC cross-chain solution of Cosmos.

Users can convert their tokens, and interact with others in various decentralized apps on OKXChain to make joint efforts to build a value-added ecosystem.

High performance

While OKXChain supports all types of DApps, it is specially designed for high-performance scenarios and high-volume transactions typical of trading activities and financial services.

Decentralized governance

OKX Review: Verdict

OKX is a well-established cryptocurrency exchange offering lots of features to its users.

OKX's security features are some of the best in the industry and they take lots of care into keeping users' assets safe.

Both desktop and app versions of the exchange are very intuitive and easy to use, there are no deposit fees and trading fees are very low.

One of OKX's biggest advantages is the fact that accepts PayPal deposits, making it one of the only exchanges accepting this method of deposit.

The biggest drawback to OKX is the fact that it does not accept U.S. citizens, there are also some limitations when withdrawing funds, hopefully, both these flaws will be corrected in the near future.

I'm a filmmaker with extensive training in multiple sectors of content creation whose films have been shown all over the world. I have also served as a speaker and jury member in multiple events. Nonetheless, in recent years, I became extremely disappointed with the course of the art world in general, and as consequence, I've developed an interest in topics I believed would become crucial for the future, namely, cybersecurity, self-education, web design, and investing in various assets, such as cryptocurrencies. All those events have driven me to launch RushRadar.
