What is OKX?
OKX is a major global centralized exchange spanning spot and derivatives trading, plus a self-custody Web3 wallet and multi-chain ecosystem. In our dataset it carries the largest reported reserve figure of any exchange we tracked, at roughly $29.9B, which speaks to the scale of assets moving through the platform. It is a common venue for both retail and professional traders, and its Web3 wallet lets users step from a custodial account into on-chain DeFi without leaving the OKX interface.
Scale and reach
OKX supports around 20 chains for deposits and withdrawals and has operated for about 9.6 years. It regularly publishes proof-of-reserves data, and the reserve figure we recorded reflects on-chain holdings where available. Combined with a decade of operation, that gives it strong scale and track-record marks and places it among the higher-volume exchanges globally.
Where it falls short in our scoring
Two things pulled OKX down. First, we did not find a dedicated public status page, so real-time incident transparency is weaker than at venues that publish one. Second, our single-location API probe returned in about 319 ms, toward the slower end of the exchanges we measured. Latency is measured from one location only, so treat it as indicative rather than definitive, but it is a real signal on responsiveness from where we tested.
What we assess
We score reserves where published, operating history, transparency signals and our own latency probe. We do not rate fees or customer support, and we make no claims about them here.
Who is OKX for?
- Active traders who want deep liquidity across spot and derivatives.
- Users who want an integrated Web3 wallet alongside a centralized account.
- People comfortable relying on proof-of-reserves rather than a live status page.
It is less suited to users who prioritise real-time status transparency, those who want the fastest possible responsiveness, or people in jurisdictions where OKX restricts access. As a custodial exchange, the usual counterparty risk applies whenever your assets sit on the platform, and published reserves are a useful but not complete safeguard, so review the exchange's own disclosures yourself before committing any significant funds.
