What Is OKX? Scale, Proof of Reserves, Safety and Use Cases

What is OKX, and when was it founded?

OKX is a crypto platform founded in 2017. It previously operated under the OKEx brand and changed its name to OKX in 2022. Two different products now sit under that brand:

Product	How it works	Control and principal risks
OKX centralized exchange	Users trade spot, eligible derivatives and conversions through an account	OKX custody and account rules control balances and withdrawals; users bear account, venue, counterparty and regional-access risk
OKX Web3 wallet	Users sign transactions and interact with onchain applications	Users bear seed phrase, signing, smart-contract, bridge and token risk; exchange-account protections do not automatically apply

In practical terms, OKX is a long-running centralized trading venue with APIs and a publicly checkable reserve process, plus a separate self-custody wallet product.

How large is OKX today?

The figures below come from different evidence classes and should not be blended into one marketing number:

Metric	Value when checked	Evidence type	What it means
Reported user scale	120M+	OKX Europe company statement	Brand reach; not audited monthly active or funded accounts
24h spot volume	About $1.38B	CoinGecko rolling snapshot	Current trading activity; it changes with the market
CoinGecko Trust Score	10/10	Third-party model	A methodology score, not government insurance or insolvency protection
45th report primary assets	$23.12B	July 2026 OKX PoR	A dated asset snapshot, not valuation or revenue
Covered reserve assets	22	OKX PoR	Assets listed in that report; it says nothing automatic about omitted items

For execution, total venue volume is less useful than volume, spread and depth in the exact market you intend to trade. A venue can report high aggregate turnover while a long-tail pair remains expensive to enter.

Why do traders use OKX?

The recurring reasons are:

1. Product breadth: spot, conversion and region-dependent derivatives in one account.
2. Execution: active books in major pairs, subject to pair-level depth and spread checks.
3. APIs: V5 account and trading APIs for dashboards, reconciliation and automated execution.
4. Checkable reserves: liabilities inclusion, wallet addresses, signatures and open-source verification tools provide more evidence than a generic solvency claim.
5. A Web3 entry point: a separate wallet covers onchain tasks, though its risk model differs from the exchange.

This does not make OKX the right choice for everyone. A user who only needs long-term self-custody, or cannot access a required product in their region, may have little reason to leave funds on the exchange.

Is OKX safe? Examine evidence and limits

No single score establishes absolute safety. A more honest review places positive evidence beside its boundary:

Check	Current evidence	What it does not prove
Proof of reserves	45th report covers 22 assets, $23.12B in primary assets, zk-STARK liability checks and address verification	Every liability, asset quality, internal control or future liquidity
Account security	Strong authentication, anti-phishing and withdrawal controls are documented	Elimination of phishing, SIM swaps, device compromise or user error
Regional entities	EEA entity discloses MiCA/MFSA CASP authorization; US entity discloses FinCEN MSB and NMLS registrations	Global access to every product or deposit insurance
Enforcement history	US DOJ records a 2025 guilty plea and more than $504M in penalties involving an OKX entity	A complete description of every current regional service
Live withdrawals	Users can test a small withdrawal through the current route	Permanent availability for every asset, network and future date

OKX’s US disclosure explicitly says customer accounts are not FDIC- or SIPC-insured. That limitation is more decision-useful than a universal “safe” badge.

What does the current reserve report show?

Selected figures from the July 2026 45th report:

Asset	Reserve ratio	User account assets	Wallet assets	Reading
BTC	105%	128,589 BTC	135,414 BTC	Disclosed wallet assets exceeded corresponding account assets at the snapshot
ETH	103%	—	—	Above 100%; open the full report for its exact scope
USDT	112%	—	—	Higher coverage does not remove issuer or chain risk
USDC	101%	—	—	Close to 100%, making future report changes worth monitoring
XRP	109%	—	—	A report-specific ratio, not a permanent guarantee

The BTC section also separates exchange-controlled assets from third-party custody. That distinction matters because a wallet total can contain more than one custody arrangement.

How to verify OKX reserve addresses yourself

1. Open the official Proof of Reserves page and note the report date and asset scope.
2. Select the latest report in the download center. The 45th report checked here had ID 499955235 and a July 7, 2026 UTC+8 snapshot.
3. Run the in-account liability check to verify that your balances are included in the zk-STARK proof.
4. Download the public address file and check the address, asset and report block height or timestamp.
5. Verify address-ownership signatures. A valid signature proves control of an address, not that funds can never move.
6. Inspect the evidence and scope for assets held by third-party custodians.
7. Preserve the report date: an old report answers an old snapshot.

What proof of reserves cannot answer

PoR is not a full financial audit. On its own it usually cannot establish:

• the absence of liabilities outside the process;
• whether assets are pledged, borrowed or subject to legal claims;
• the quality of internal controls, related-party activity or operating cash flow;
• the ability to meet a simultaneous stress withdrawal;
• customer priority in an insolvency proceeding.

The stronger workflow is to combine PoR with the regional entity, account controls, conservative custody size and a real withdrawal test.

Why does OKX differ by country?

Region example	Public boundary	User action
EEA	OKX Europe Limited discloses MiCA/MFSA CASP authorization	Read EEA terms, available products and the regional fee schedule
United States	OKX US offers restricted spot, buy, sell and convert services; some jurisdictions are unavailable	Use only the US products allowed for the account
Other regions	Contracting entity and derivatives eligibility may differ	Rely on the verified account and current terms, not a global tutorial

A global feature page does not prove that the same feature is available to your account.

A practical first-use checklist

1. Enter through the OKX registration page, then identify the contracting entity and confirm the products available in your region. The referral offer provides 20% off trading fees.
2. Complete verification, then inspect the products actually enabled in the account.
3. Configure strong authentication, anti-phishing and withdrawal protections.
4. Confirm asset and network, then make a small deposit.
5. Place a small trade and record the actual maker/taker fee and slippage.
6. Withdraw a small amount to an address you control.
7. Keep the exchange balance proportional to the current task, not the platform limit.

For dashboards or bots, use the OKX API key security guide. For execution costs, enter the account’s actual rate in the OKX fee and slippage calculator.
